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 early
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.

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 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.
False Negative Pregnancy Test With Mirena?
A long term birth control option, Mirena is popular with women who want to space out their pregnancies or avoid becoming pregnant without actually having to undergo a tubal ligation. This brand of IUD has proven to be more 99 percent effective and has demonstrated no long lasting ill side effects found with other forms of birth control, including bleeding, infection, or extreme weight gain. However, women who use Mirena and feel like they may be pregnant may wonder if their IUD is causing them to get a false negative result when they take an over-the-counter pregnancy test. Doctors insist that Mirena does not cause false negative test results, however, and in most cases prevents pregnancy from occurring in the first place.
In fact, studies have shown that Mirena does not inhibit or mask the presence of hCG in the bloodstream. If a woman has this IUD and believes she is pregnant, yet gets a negative test result, it more than likely can be assumed that she is not pregnant at all. Even in the unlikely event that she is pregnant while using Mirena, she may be testing too early to get an accurate test result. If she is very early on in the pregnancy, particularly before six or seven weeks, she may not have enough hCG in her urine for the test to detect with accuracy.
Because this IUD’s chemical makeup does not compromise the presence of the pregnancy hormone in a woman’s body, a woman who keeps getting a negative test result, but feels that she is pregnant may also be testing at the wrong time of day. Ideally, over-the-counter tests should be taken first thing in the morning. This first morning urine is considered to be of higher quality and will contain more hCG if a woman is indeed pregnant.
Can You Get A False Negative Pregnancy Test With Mirena?
When asked if it is possible to get a negative pregnancy test result while using Mirena, gynecologists confirm that such a scenario would be nearly impossible. In fact, women who are using this IUD and think that they are pregnant may actually be experiencing the side effects of the birth control itself, which can in fact mimic pregnancy. This birth control can cause a woman to feel nauseated, have tender breasts, and feel bloated or like they have put on weight. These symptoms occur because of the amount of pregnancy preventative chemicals being released into her bloodstream, however.
Designed to last for five years, Mirena could become less effective as it nears its expiration date. In this event, it is possible that a woman could become pregnant, particularly if she is only a few weeks away from needing to have her IUD replaced with a new one. Even so, when she takes a pregnancy test, she should get a positive result if she were truly pregnant. If she gets a negative result, it cannot be linked necessarily to her Mirena device. With that, she may consider what other reasons could cause her to be getting a negative result.
