Pharmacy tests are great! A real modern facility for anyone trying to conceive right? However, they can also be accompanied by headaches in some unusual situations. One of the countless situations that we can go through with the use of home tests are false positives, but there is still a positive from the pharmacy test and a negative from the blood test .
These events are to make any hair tryer stand up, aren’t they? The question of which results to take into account is cruel and can hinder the understanding of many. So how about unraveling why the pharmacy test is positive and the blood test is negative?
One of the main explanations for the pharmacy test to give positive and negative blood is the amount of HCG present in the woman’s body. Some tests can be so sensitive that they are even more efficient than the blood test! Of course, this factor is a double-edged sword, because for this to happen, the minimum sensitivity of the laboratory has to be the highest, that is, 50mUI. Some brands have a minimum sensitivity of 10mUi and then any amount approximately or theoretically higher than this would be detected, such as the Famivita pregnancy test that you can purchase here in our online store. We must also take into account the intensity of the color of the line, if very light, it may be an indication of a very early pregnancy.
The risk of doing the test before the delay must also be taken into account. Some laboratories that do qualitative beta HCG may not consider the blood test positive (light line) to be positive. In fact, most laboratories only determine the positive when the positive leaves no doubt about the positive result . In these cases where there are doubts, they may possibly indicate that the woman will be tested again in a few days.
In all cases, it is advisable to repeat the HCG beta test in one week. The laboratory itself advises the woman to redo to see if the amount of HCG released in the body increases. If the hormone progresses, then the result is considered positive . But if it continues to be negative, there is probably something wrong with the pregnancy tests. What are the cases where the test may be wrong?
When Is There Something Wrong in the Pharmacy and Positive Test and the Negative Beta?
An episode involving tests that can happen, is the pharmacy test to detect another hormone in the body that has the same structure as HCG, LH! This phenomenon happens rarely and in certain periods of the cycle when this hormone is on the rise, close to the ovulation period that for many women is in the middle of the cycle. Theoretically at the end of the cycle, this positive by LH would not be possible because ovulation would have passed a few days ago, but it is possible that the hormone is out of control that bring this positive.
Another factor that can be positive in the pharmacy test and negative in the blood test is the intake of drugs that contain HCG and are eliminated through the urine. Some women use certain substances to treat fertility (break eggs) such as Choriamon, Choragon and Ovidrel . It is also possible to ingest HCG through weight loss medications that you may have. Other medications would not interfere with the results of pregnancy tests, as is the case with the morning-after pill for example. They do not have the ability to manufacture HCG. This hormone is exclusive to pregnancy or can be ingested in some medications.
There is also a chance that the pharmacy pregnancy test itself will have some kind of problem. Some brands can often give false positives to several women on several occasions. To remove the doubt whether or not your test gave a false positive, it is advisable to do another one from another trusted brand. If the test continues to be positive and the beta negative after 15 days, it is advisable to see a doctor to see what is actually happening.

Since I imagined myself as a mother, in my thoughts everything seemed to be much easier and simpler than it really was, I expected to get pregnant as soon as I wished, but it wasn’t that simple. The first pregnancy was smooth, but my daughter’s birth was very troubled. Joana was born in 2002 with a weight of 2930kg and 45cm, from a very peaceful cesarean delivery but she had already been born with congenital pneumonia due to a broken bag not treated with antibiotics even before delivery.
