Without knowing exactly what went wrong, no reasonable person should blame themselves for false positive pregnancy tests. Sometimes, it just happens. In order to diagnose the issue accurately, it is important to address the faults in the pregnancy tests and determine the method that will be of significant priority. Without a precise and early determination, the problems identifying false positive pregnancy tests will continue to cause tension for countless anxious and stressed individuals.

In conclusion, the results could be due to a foreign substance in the body that might be mistaken for pregnancy hormone, errors in applying the pregnancy kit, deterioration of the package due to room temperature negligence, or medication treatment to increase fertility that contains hCG. Additionally, there may be faults in the construction of the pregnancy test, which in some cases can lead to inaccurate diagnosis of pregnancy as the real fertility-subordinating problem.

What should you suspect false positive pregnancy tests? It often occurs with any home pregnancy test due to a number of causes, including an atypical result where the test reading resulted in a high level of pregnancy hormone, but not an actual pregnancy.

After receiving a false positive pregnancy test, there are a number of actions you can take, depending on the possible diagnosis: embrace and prepare, consult your doctor for further diagnosis, ask for necessary advice or studies about fertility, prevent or wait a few days to retest the pregnancy test.

It can be extremely frustrating if you are ready to become a parent and are told by a pregnancy test that you have a false positive result. However, keep in mind that a false positive pregnancy test is more common than you may think, and it is important to not let negative thinking add to your already tense feelings. You need to be relaxed in both body and mind to know what needs to happen next.

Definition of False Positive Pregnancy Test

It is important to remember that molar pregnancies typically happen when there is a specific problem at the point of fertilization and cannot be due to any actions the woman took during attempts-to-conceive.

. Molar Pregnancy. Quite rarely, pregnancy tests could be showing a false positive due to a molar pregnancy. This is the rare cause of a false positive test. A molar pregnancy occurs when there is a problem with the fertilization of an egg by a sperm which means an embryo doesn’t develop properly. The quantity of the hormone human chorionic gonadotropin (HCG) produced is higher than in a normal pregnancy. This hormone is the hormone tested in home pregnancy tests. It is important not just to rely on home pregnancy tests to differentiate between a viable normal pregnancy and a molar pregnancy. If you have any reason to suspect you have a molar pregnancy you should seek advice from medical professionals.

There are several causes of pregnancy tests showing a false positive. False positive pregnancy test results occur when the test is positive but you are not actually pregnant. Below are potential reasons or tests which could have caused the false positive.

Causes of False Positive Pregnancy Tests

Causes of “False Positive Result” A “false positive result” is where the pregnancy test gives a positive indication of pregnancy when in reality there is none. A “false positive result” may be as a result of several reasons such as: – Use of fertility drugs – Ovarian problems – Pregnancy less than six months postpartum – A medical condition such as a pituitary gland tumor Other uncommon issues can include a test done incorrectly, an ectopic pregnancy, certain types of cancer, and early miscarriage.

Many women who perform a home pregnancy test get a “false positive” result. This is so frustrating and often very devastating, especially if the woman in question has been trying to conceive. To begin with, the pregnancy test works by detecting the hormone Human Chorionic Gonadotropin (HCG) in the woman’s body through urine. HCG is always secreted from the placenta immediately following implantation. Implantation usually takes place six to twelve days after fertilization of the ovum. The woman’s body usually produces a lot of the hormone – more than the usual minimum detectable levels. A woman is termed “pregnant” if the hormone is detected in her blood at a concentration of mIU/ml or higher. Blood levels are usually tested in the laboratory but can be done at home using a home pregnancy test kit.

Medications and Medical Conditions

Guideline : Better comprehension of factors that contribute to false positive pregnancy testing results will enhance antenatal care for women by reducing the attention to the differential diagnosis. Low Early Outcome Rate (EOR) decreases sensitivity of pregnancy tests since products of conception production is associated with hCG secretion. However, whenever a potentially fertilized ovum implants in the endometrium, trophoblast invasion extends into the endometrial tissue and vessels, releasing indicators such as hCG into blood and other tissues. When hCG released from the trophoblast reaches sufficient concentrations in maternal blood or urine, it is detectable, providing the basis for pregnancy tests. Two types of pregnancy tests are available. Home pregnancy tests based on the immune-assay of an hCG pregnancy test kit are easy to perform and widely used.

Medications – There are several medications that may cause a false positive pregnancy test. They include anticonvulsants, antihistamines, hypnotics, oral contraceptives, and some fertility therapies. Rapid weight loss – such as with gastric bypass, a low-carbohydrate diet, or long runs – can disrupt the balance of a woman’s reproductive hormones. Medical conditions, such as breast cancer or ovarian cysts, may also cause false positive pregnancy tests. Some other conditions are rare liver disorders and some forms of cancer.

User Error

Frequent misreading problems include not waiting long enough before checking results or not reading the results within the stipulated waiting time. This explanation means that a fleeting glance at the test may cause an incorrect result. Waiting for the proper amount of time – the amount of time is usually indicated in the test instructions – is essential to avoid a false positive pregnancy test. Significant liquid interference is usually from dipping the test in liquid for a more extended period to allow liquid to seep past the test window. All pregnancy tests can provide inaccurate results when left in urine for a more extended period. Lingering liquid is likely to saturate the window, leading to an invalid test result.

In most cases, user error leads to a false positive pregnancy test. Pregnancy tests are easy to use, making them an accessible option for women of all ages. Despite that, it is possible to inadvertently misread and misinterpret the pregnancy test. The most frequently encountered issues that lead to false positive results include expiration and storage problems. Test strips often expire a few months after production, especially when not adequately stored under proper conditions. Both false positive and false negative results are likely to happen when the strips are old, stored inappropriately, or exposed to harsh sunlight.

Impact of False Positive Results

The term “false positive result” refers to a positive urinary hCG result from a non-gravid specimen. From the laboratory’s perspective, a false positive result is a positive non-pregnancy hCG test result, and problems with the hCG assay are most often the cause. In our laboratory, only .% of the women entering the infertility cohort received a notification of a false positive result. Because of the impact of pregnancy in the lives of patients in gynecology, infertility services, and oncology care, those practices generally are the most upset about that .% of the woman who receives erroneous information about her pregnancy status. Prior to automated testing in , our laboratory would obtain a second specimen from the affected patient to confirm the positive hCG result. Immunometric assays have reduced that occurrence to about three to four cases in a year. The electronic medical record has made the identification of the affected patients more reliable and the practitioner notification process more controlled.

Medical diagnoses have real significance for a patient’s life and peace of mind. A patient who is experiencing physical or emotional symptoms and receives a benign pronouncement from the medical establishment can feel abandoned and without resources. Patients who mistakenly believe they are pregnant can experience significant lost opportunities and can make decisions that they regret. In an infertility patient, realization of a false positive result has a lasting impact, disabling the patient’s sense of hope when the same person might have had expectations crushed over years of infertility treatment. Understanding the factors that contribute to a false positive error in hCG testing is essential.

Emotional Distress

Keywords: Pregnancy testing, Fertility, Emotional distress, Loss, False positives.

Women who receive false positive results may experience a range of negative emotions in the period following testing. Despite the potentially negative consequences of a false positive result, little is known about how women come to understand their results. One paper has examined the narratives of women receiving a miscarriage diagnosis through an analysis of online forums and reported that women who were affected felt that they had been rushed or pressured into drawing incorrect interpretations from their positive results. In a qualitative study of women attending fertility clinics undergoing a variety of tests, there was a risk of “unwarranted autonomy erosion” when testing regimes demanded independent decision making without sufficient psychological support from the attending physician.

Prevention and Minimization of False Positives

These are usually attributed to inaccuracy in perinatal determination, but there is a potential supplier connection. This was verified in a research from  showing two brands of homebox pregnancy tests having skewed differential at different gestational periods, with the market that doctors no longer recommended them based on inconsistent results. Sonnenfeld, a microbiologist and book author, states that “many manufacturers claim % precision and % confidence, but that’s not my experience.” One of the main reasons for providing an insufficient sample size is because many generic pregnancy tests only contain the minimum amount of test strip and thus insufficient absorbent member to capture the correct amount of specimen to display free HCG. If the test has a narrow collection strip space, Luteo Laboratories Ltd., for example, tests the maximum HCG concentration of  MIU/mL with a . mm sleeping strip and  mm wide path for presenter sample.

Preventable sample or procedural errors include the use of inappropriate assay types (such as visual instead of automated assays and/or inappropriate test devices), inappropriate protocols, problems in quality control, test kit defects (such as expired test kits or torn pouches), and patient error. Visual POC assays have been found to have higher false positive rates than automated instruments and ELISA tests. POC assay errors (false positives) appear to be higher in areas where microenterprise research stocks related to HCG pregnancy tests have been established. In home pregnancy tests, the possibility of getting false positive readings increased when the test was physically designed not to allow the test strip to be submerged properly, which causes a problem with wicking. Other laboratory scientific articles indicate there is an “anti-ass bimbo” positive rate with the use of home-based pregnancy tests.


We must be aware of the fact that no possible method can offer an absolute guarantee, as errors on pregnancy tests will likely continue in the future. Companies that plan these diagnostics should invest time in consistent research and develop tests resulting in fewer errors. These changes will not only protect the state of emotional distress from the uncertainty of pregnancy that the majority of women undergo but will also safeguard the health of many patients who depend on this information.

This type of error can be harmful in different fields. Apart from important changes at an emotional level, false positive pregnancy tests can affect clinical decisions related to delicate physical executions such as chemotherapy or radiation therapy. In the case of politoxicomania, it can frustrate professional programs that assist pregnant women with addictions. The microscopic structure of pregnancy tests shows two areas capable of reacting as a function of hCG.

Several factors can prompt the occurrence of a false positive pregnancy test. A previous pregnancy that had lasted no more than – weeks could be the cause. Conversely, a more recent miscarriage, by contradiction, can lead to a false positive or give an unequal result. Contraceptives or drugs that increase prolactin, associated with the hormone hCG, can also cause false positive tests. Pregnant women diagnosed with illnesses that produce excessive amounts of hCG should keep in mind that false positives can occur. One possible solution is to evaluate the increase in the values of hCG obtained in the tests, which makes it possible to prevent the occurrence of similar errors.
