Undeniably, entry into motherhood brings great joy and happiness to the life of every woman now that soon you will become a mommy. Nevertheless, you might feel wildly excited and terrified at times. During this period, your body is changing, primarily due to the shift in hormonal secretions which comes with numerous signs in your body. Identifying these signs and interpreting them as signs of pregnancy is one of the hardest things that every woman faces unless you perform a pregnancy test. More often, pregnancy tests measure the amount of Human Chorionic Gonadotropin hormone (HCG) usually present in the urine. It is produced in the early stages of pregnancy, and its concentration gradually increases with time. The levels of HCG often vary from one person to another, and in situations where it’s low, the negative pregnancy test may arise.
What is a false negative pregnancy test?
Ideally, a false negative pregnancy test is usually a pregnancy test that gives you a confirmation results that you are pregnant when actually, you are. Time, negative pregnancy test often comes with mixed reactions to the victims as they may come against their wishes. For instance, a mother who was earnestly waiting for a child may get heartbroken by the negative results. However, some vital factors usually lead to this uncontrollable situation.
Factors that result in negative pregnancy tests
1. Test strip low sensitivity
As mentioned above, the HCG levels often vary from one person to another. However, at reduced levels, the probability of the test strips or digital strips to detect the concentration of the HCG in urine is substantially reduced. Also, some testing devices like midstream quickly classify a 19mlU/ml concentration as low just because it did not attain the 20mlU/ml level. Therefore, device sensitivity is a vital issue in pregnancy testing.
2. Too early testing
If an individual opts to take an early pregnancy test in its infancy, then the most immediate results to get is a false negative pregnancy result. However, most initial tests usually take place before or close to implantation. Therefore the formation of the HCG hormone in the blood or urine is in its low concentration or yet to be formed. In some cases, most accurate results can be found after missing some periods. It is, however, advisable to undergo testing after three to five weeks to avoid erroneous results.
3. General body weight
A recent clinical study postulated that most heavyweight pregnant women have a higher tendency of getting a false negative pregnancy test. General body weight can be explained well with the body mass index, in that, the lower the BMI index, the lower the concentration level of the HCG hormone. This phenomenon explains the increased false negative pregnancy tests in heavyweight individuals
4. Too diluted urine
Performing urinalysis test on a highly diluted urine can be another reason. Diluted urine can arise as a result of too much intake of water thus the first-morning urine is recommended for testing. Another alternative is performing blood analysis other than urinalysis that is susceptible to dilution.
5. Under medication
Almost all over-the-counter drugs available are designed to deal with a broad range of medicines that people use. However, some drugs are known to alter pregnancy tests, therefore, giving out undesired results by hindering the accuracy of the test used. Normally, pregnancy tests results cannot be reliable if the patient is undergoing medical or taking prescriptions of some known medicines.
6. Impending miscarriage
In the initial stages of pregnancy, many women are not even sure or aware that they are pregnant until they start missing their periods. Usually, reduced HCG hormone levels may be another sign of impending miscarriages. Others may start dismissing bleeding as albeit heavier than an average period, which in the real sense is a miscarriage. This cases often denote a false negative pregnancy result.
7. Hormonal imbalances
Just like standard medications, hormonal imbalance of an individual significantly affects the outcome of the test. Most women often wake up to realize that they have this problem on a pregnancy test day. HCG hormone levels tend to fluctuate while aging. Due to hormonal fluctuations, women usually miss periods, gain abnormal weight or even receive severe thyroid complications. These imbalances cause false negative results.
The steps to follow an accurate test
• Knowing when to take the test
The time and when to take the test is a vital indicator of how to get the right results. Always waiting for one to two weeks after missing your periods is the ideal time. There is also the miscalculation error whereby some women experience irregular period intervals although they are a few.
• Perform tests in the morning
For ideal and accurate pregnancy test results, the testing should be done with morning urine due to its unaltered concentration that has the highest levels of the HCG hormone.
• Following instructions
Some results usually prove otherwise do to inability to follow basic testing instructions to the later. Different test kits have different instructions and specifications written on the test leaf. For instance, the length of time taken for the stick to soak before removal have a significant effect on the results. You need to follow them keenly.
• Avoid drinking fluids before testing
According to the FDA recommendations, too much intake of fluids alters the accuracy of the results. As earlier mentioned, liquids or drink brings about dilution, therefore, hampering the test results.
• Seeking medical support
Most women prefer privacy and confidentiality while performing their pregnancy tests. However, it is advisable to seek consultations from physicians in case of any doubt and assistance. It is wise to tame the problem before it turns a white elephant.
• Urine collection
Since urine sample here is the vital tool for testing and analysis, proper selection mechanism should be observed to avoid unnecessary contamination from foreign agents that can bring false results. The cans used must be clean and free from any substances are must be dry before use. Most doctors prefer blood testing to avoid issues related to dilution and contamination.
As a closing remark, a pregnancy test is not a walk in the park affair. Proper psychological preparations are important to avoid terrible heartbreaks and emotional problems. Also, unlike the negative results, false positive results are not there although there are minimal exceptions while testing HCG hormone levels on fertility testing of an individual. It is, however, significant to conduct frequent visits to a doctor for further examinations and to avoid creating a mountain from a molehill.
