Pregnancy test

Q1. Pregnancy test principle:

A:With immunoassay test techniques and chromatographic principle, use the specific antibody fixed on the membrane, and then with Double antibody to detect the hCG antigen in the specimen. So, we research the simple chromatographic immunoassay reagents, which can help individuals and doctor make initial diagnosis.

Generally, males and females’ β-hCG would be 5-10mIU. The detected of Pregnancy test minimum amount of 25mIU. (That is the number of detected report from USA FDA.) In the early pregnancy test, it can detect about 25mIU. After a week, β-hCG rise to 6000mIU, but the β-hCG in urine will different because of each person's physical condition.


Q2. Does the Pregnancy test product could accurate know be pregnant or not? Is it has any difference with hospital?

Some people would have abnormal pregnancy like ectopic pregnancy and vesicular mole etc. Even if other cancer diseases and false pregnancies, it could have this kinds of appearance. Therefore, if the result is positive, you still need to go to the hospital for further check.

Q6. Why is there no band visible in my pregnancy test? Neither one band nor two bands shows.

A:The test would be unavailable if the sample is out of the specimen region.(Do not immerse the strip-type pregnancy test past the arrow on the strip. And if you use the card-type one, do not put too much and do not put the sample directly into the specimen region. When you use the midstream type, do not immerse it over the plastic region.)


Q7. Do I need to use many kinds of the Pregnancy test products?

A:According to the psychological factors that want it to be more accurate, lots of people test it again and again. In fact, only if you do the right methods and not the expired products, you would not need to test again. Otherwise, when interpreting the Pregnancy test products, some in early pregnancy might appear 1 deep 1 pale red lines, which means in early pregnancy the hCG would be low concentration. In other situation, if the Pregnancy test products be soaked into urine too long, it would make the reading area no appearance or color smudged and failed concentration. No matter which kinds of Pregnancy test products, before using it should read the direction carefully, that could avoid failed using and concentration.
