THE TWENTY-YEAR DEATH

A breathtaking first novel written in the form of three separate crime novels, each set in a different decade and penned in the style of a different giant of the mystery genre.

The body found in the gutter in France led the police inspector to the dead man’s beautiful daughter—and to her hot-tempered American husband.

A hardboiled private eye hired to keep a movie studio’s leading lady happy uncovers the truth behind the brutal slaying of a Hollywood starlet.

A desperate man pursuing his last chance at redemption finds himself with blood on his hands and the police on his trail…

Three complete novels that, taken together, tell a single epic story, about an author whose life is shattered when violence and tragedy consume the people closest to him. It is an ingenious and emotionally powerful debut performance from literary detective and former bookseller Ariel S. Winter, one that establishes this talented newcomer as a storyteller of the highest caliber.

Amazon Exclusive: Essay by Author Ariel S. Winter

It is impossible to say when a book begins. Did it start at birth, or when I learned to read, or when I set out the first words that grew into a novel?

I am inclined to say that The Twenty-Year Death began when I took two university courses: Hardboiled Fiction and Film Noir, and Faulkner, Fitzgerald, and Hemingway, even though I wrote it many years later.

But perhaps the truer answer lies with that Chandler send-up, Who Framed Roger Rabbit?, my favorite movie of childhood…and still today?

What I do know is that The Twenty-Year Death is not the book I set out to write.

That ambitious book was meant to be David Mitchell’s Cloud Atlas as written by W.G. Sebald. There would be a straightforward first-person narrator, a close approximation of myself, and there would be the books the narrator read. These books would appear in full, so the reader of the novel would read the reading of the narrator—mysteries, romances, westerns, sci fi, and “literary” fiction, his taste would be catholic.

I began the frame narrative, and then I wrote the Georges Simenon pastiche Malniveau Prison, a one-hundred and fifty page replica of an Inspector Maigret mystery.

I didn’t stop there. Next up was a romance, a love story between the full-sized daughter of retired circus midgets and a newcomer to their island home. Oh, I was ambitious.

And the book failed.

Still I clung to Malniveau Prison. No writer, especially one young and unpublished, can bear to see his hard-earned work go to utter waste. I didn’t have my novel, but I had a novella, and I knew it was good.

I sent it to an agent. It was January 1st when he got back to me. Or that is how I remember it at least, and it has the poetic ring that appeals to me as a novelist.

“I liked it a lot,” he said. “But it feels like a half-novel.”

That was all the encouragement I needed. I attacked Malniveau Prison, and it doubled in size.

There was talk of a series, but I didn’t want to write a series. Unless…unless…what if the recurring character in the novel was not the detective, but some other side character…

The American writer Shem Rosenkrantz seemed the obvious choice. And where would a great American novelist go after France…

Hollywood, of course. And Hollywood meant Chandler. After all, I had one pastiche on my hands. Why not two?

Before I even began on the Chandler pastiche, I had conceived of the Jim Thompson book as the novel’s logical conclusion. So, like a movie studio that green lights two sequels after the success of the first film, I went into The Falling Star knowing how Police at the Funeral would end.

Is this how all novelists work? Do their books rise like the phoenix from the ashes of their mistakes? I have known several novelists in my lifetime, yet only one to call friend, and still I do not know. It is how this book came to be.

Or is it? Do I really know how I came to write The Twenty-Year Death? Does any novelist know how he came to write a book?

False Negative Blood Home Pregnancy test, Reason or Causes and How Common is it

How common is a false negative pregnancy test

There are several reasons for false negative pregnancy test to take place. On the other hand, it is important to know that it is rather rare for false negative pregnancy test to happen. Most pregnancy tests have high success rates, mostly 97%-99% precision range. It is also rarer for a false negative blood pregnancy test to occur. Here are some of the common reasons that can cause false negative pregnancy test results.

Reasons or causes for false negative pregnancy test

Taking pregnancy test to earlyPossible have false negative blood pregnancy test

One of the most usual reasons for a false negative home pregnancy test result is making an early detection attempt. Pregnancy tests differ in sensitivity, meaning how soon they’ll be able to detect the hCG or Human Chorionic Gonadotropin in the urine. There’s a possibility that even though your ovum is already fertilized, your body has not yet started to secret the hCG for the pregnancy test to measure, giving a pregnancy test wrong result. Your body needs some time for the hormone to rise in a level high enough to be detected in the pregnancy test.

It is possible that drinking lots of water and then testing late in the day can affect the test’s accuracy and can be the reason for you to get false negative pregnancy test . Most manufacturers recommend testing in the morning to avoid getting false negative pregnancy test results. However, this must only be an issue in the first few days after missing your period. After that, having a test even late in the day should provide a positive result.

Errors in using the pregnancy test

Another reason for you to obtain a false negative pregnancy test is if you make some errors while using the test strip. You may not be putting enough urine on the test that’s why even if you are pregnant but negative test result showed in the strip.

To make sure that you will not get false negative pregnancy test, it is important to read the test results in the specified reaction time. If you’ll let the test sit longer than the stipulated reaction time, the pregnancy test is invalid. This can cause the test to show false negative pregnancy test results.

If you got negative results in your pregnancy test but you think that you are pregnant, then wait a few more days and try again. Moreover, if you got different test results on several pregnancy tests, it is better to undergo a blood test to obtain an accurate result.

7 Causes for a False Positive Pregnancy Test

Home pregnancy tests are a common tool used to find out if you’re expecting. Most at-home pregnancy tests are dip sticks, which are placed into the urine stream. The stick is then able to detect human chorionic gonadotropin (hCG), a hormone produced during early pregnancy.

Some pregnancy tests detect hCG very early in pregnancy. Reputable home pregnancy tests can be highly accurate, but they aren’t foolproof. False positives and negatives can occur for a variety of reasons. It’s also important to remember that once you have a positive pregnancy test, see your doctor to begin early prenatal care.

Read on to learn more about false positives on home pregnancy tests.

It’s possible to have a positive pregnancy test even if you aren’t technically pregnant. This is called a false positive, and is sometimes caused by a chemical pregnancy. A chemical pregnancy occurs if a fertilized egg, known as the embryo, is unable to implant, or grow, very early on. This can happen for a wide range of reasons.

Early pregnancy loss doesn’t occur because of anything the woman has done. It may be the result of issues within the uterus, such as fibroids, scar tissue, or a congenital uterine anomaly which causes the uterus to have an irregular shape.

Low amounts of certain hormones, such as progesterone, can reduce the likelihood of implantation and embryo growth.

Some causes of chemical pregnancy are unknown.

Chemical pregnancies are thought to be very common, but they typically go undetected if a pregnancy test is not taken. These early test results, when wrong, can be emotionally draining. For that reason, it is recommended that you wait to use an at-home pregnancy test until one week after you expected your period to start.

Sometimes a fertilized egg can implant itself outside of the main cavity of the uterus. This causes an ectopic pregnancy to occur. Ectopic pregnancies usually happen if a fertilized egg gets stuck in a fallopian tube during its journey to the uterus. This can happen if the tube has scar tissue, inflammation, is misshapen, or if there is a history of past uterine infections. This type of ectopic pregnancy is also known as a tubal pregnancy.

Ectopic pregnancies can also occur in the cervix, ovary, or abdominal cavity. An ectopic pregnancy cannot continue to become a normal pregnancy. The embryo is not viable because there’s no place for it to grow or thrive outside of the uterus.

The embryo will still produce hCG, even though it has implanted in the wrong place. That can cause a false-positive reading on an at-home pregnancy test.

Ectopic pregnancies are medical emergencies. Ectopic pregnancies can be damaging to the woman if left untreated, causing extreme blood loss or loss of the reproductive organs. Symptoms of ectopic pregnancy include:

  • nausea and sore breasts, which are also symptoms of a normal pregnancy
  • sharp waves of pain in the abdomen, pelvis, shoulder, or neck
  • severe pain on one side of the abdomen
  • light to heavy vaginal spotting or bleeding
  • dizziness or fainting
  • pressure on your rectum

Seek immediate medical help if you suspect an ectopic pregnancy.

You may continue to test positive for pregnancy following the loss of a pregnancy, either through miscarriage or abortion. During pregnancy, hCG levels continue to rise as the placenta grows, doubling every few days and peaking at around 10 weeks. When a pregnancy ends, hCG levels begin to recede, but it’s a slow process. The hormone can remain in your blood and urine for up to six weeks following the loss of your pregnancy. It’s possible to have a false-positive test until your hCG levels return to their prepregnancy state.

If the miscarriage was spontaneous, it’s also possible that not all of the pregnancy-related tissue was eliminated. This will cause hCG levels to remain elevated. When this occurs, a minor surgical procedure called a dilation and curettage is often required to remove the tissue.

Like most things in life, at-home pregnancy tests aren’t foolproof. It’s important to follow package directions exactly and to check the expiration date prior to use. Even with these safeguards, user error can occur. One of the most common mistakes is taking the test too early during your cycle. This can cause either a false negative or a false positive.

It’s also important to use the test when your urine is not diluted excessively with water and is very concentrated, such as when you first wake up in the morning.

Leaving the dipstick in your urine stream for the exact amount of time allotted is also important. Considering setting a timer on a stopwatch or your phone. That can help you track how long the dipstick has been in your urine stream. You’ll want to use a timer again while you wait for your results. Checking your results during the result time frame is also important.

Sometimes an evaporation line can be mistaken for a positive pregnancy test. Some at-home tests show two lines when hCG is detected and one line when hCG is not detected. The lines are usually a bright color, such as pink, red, or blue. Sometimes, a faint-colored second line will appear. This line may represent an early pregnancy or it may be an evaporation line. It’s probably an evaporation line if the line is completely colorless.

Evaporation lines may show up on a test you view after your urine has evaporated completely. Sometimes they’re caused by hormonal levels which don’t represent pregnancy. The best way to avoid being confused by an evaporation line is to follow the test’s timing directions exactly as they are given.

If you’re trying to become pregnant under a doctor’s care, you may be taking fertility medications. One of these is the synthetic hCG trigger shot, sold under the brand names Novarel, Pregnyl, Ovidrel, and Profasi. The hCG shot helps follicles release mature eggs. It may cause a false-positive reading on an at-home pregnancy test, particularly if the test is taken too early.

Other medications can also cause false-positive pregnancy tests. They include but are not limited to:

  • antianxiety medications, like diazepam (Valium) or alprazolam (Xanax)
  • antipsychotics, such as clozapine or chlorpromazine
  • anticonvulsants, like phenobarbital or other barbiturates
  • Parkinson’s disease medications, including bromocriptine (Parlodel)
  • diuretics, like furosemide (Lasix, Diuscreen)
  • antihistamines, including promethazine
  • methadone (Dolophine)

Rarely, certain medical conditions can cause a home pregnancy test to give a false positive. These include:

  • a urinary tract infection
  • kidney disease that causes blood or white blood cells in the urine
  • ovarian cysts, particularly corpus luteum cysts
  • more serious diseases such as ovarian cancer
  • pituitary problems (very rarely)

A positive at-home pregnancy test result should always be followed up with a doctor’s appointment. Your doctor may give you a urine or blood test to confirm the results and monitor your hCG levels. You may also get a transvaginal ultrasound to look for the gestational sac as confirmation that the pregnancy is proceeding normally.

If you have received a false positive, your doctor’s visit will determine that. It might be an incredible relief to find out you are not pregnant. But if you were excited by your early results, it can be very upsetting. It’s important to remember that false positives do happen and are not an indication that you will never get pregnant.

If you’ve been trying unsuccessfully to get pregnant for some time, particularly if you are over the age of 35, consider working with an infertility specialist. There are also support groups where you can find inspiration and obtain knowledge from women who have been through the same thing. Working one-on-one with a therapist, clergy member, family member, or trusted friend can also be beneficial.

False Negative Pregnancy Test

Jump to Article Section

A false negative result on a pregnancy test means that the test has told you you’re not pregnant when in fact you are. This can sometimes be frustrating, as your anxiety is already apt to be heightened if you’re taking a pregnancy test. There are plenty of choices that confront you when you arrive at the store to buy a pregnancy test. It’s important that you choose one with a high sensitivity to decrease the chances of a false negative test result. Most experts say to wait to take a test until you’ve missed a period, or 14 days after conception, to get accurate results. Many OB/GYNs recommend against testing before a missed period.

Causes of a False Negative Pregnancy Result

There are numerous reasons why false pregnancy test results happen. The most common cause of these results is a missed reaction time. It’s so important that you follow the directions on the box, which indicate reaction time — the time required for the test to give you accurate results. Some pregnancy tests, such as the digital EPT Pregnancy Test, take three minutes, while other tests may take as long as four minutes, or even up to 10 minutes. Reading the directions before starting can prevent you from missing the reaction time. Allowing a test to sit for too long can also produce false negative results.

Another common mistake women make is testing too early in their cycle, within a couple of days after suspected conception. Even blood tests don’t work that quickly. It’s important you wait until you’ve missed a period — or 14 days after conception. Prior to this, levels of the pregnancy hormone hCG (human chorionic gonadotropin) are too low to be detected. Home pregnancy tests vary in their ability to detect small amounts of hCG in the urine, and hCG levels rise at different speeds in different women. Despite a negative test result, it’s very possible that you are pregnant, but the hCG levels are too low for a test to accurately detect it.

Another cause of false-negative pregnancy test results is erratic or improper testing techniques. Most test sticks need to be saturated in urine to get accurate results. If you do not leave your test strip in the urine long enough, it could give you false negative or false positive pregnancy test results.

Check the date on the pregnancy test before purchasing it. Out-of-date tests will not give you results you can trust. Also remember that certain fertility medications and rare medical conditions may affect the results of pregnancy tests, and false negatives could be more common in these situations.

What Do You Do About False Negative Results?

The best thing you can do is to make an appointment with your doctor. He or she will be able to determine whether or not you’re pregnant. Your doctor will test you by examining a sample of your blood. Blood pregnancy tests are able to detect much lower levels of hCG, providing better results and reducing the chances of false negatives.
