How To Test For Pregnancy Using Home Pregnancy Test Kit?

I bought a pregnancy test which only requires 3 mins to find out the result. I took the test and after 3mins it was Clear/Negative. then after an hour i was shocked it turned positive. There are 2 lines created the other line is light which will result in positive if you will look at the instruction. What is the accurate result for this?

Dear Madam, Hi
I can understand your concern.

The given result is weak positive for pregnancy, hence needs to be repeated or blood hCG test to be done to confirm the pregnancy.

Home pregnancy tests (HPTs) are quite accurate. They work by detecting the presence of human chorionic gonadotropin (hCG) in the urine, which is produced when pregnancy occurs.

Levels of hCG are very low in the beginning of a pregnancy.

The levels of hCG increase as your pregnancy progresses, peaking at around 8-11 weeks, before dropping to a lower level at 12 and 16 weeks.

Therefore it’s normal for the result on the pregnancy test to be either fainter or darker than the control line. The reason it may be fainter could be due to less hCG in your urine, especially very early in your pregnancy. It may be darker if your pregnancy is more progressed.

Ideally, the test result should be read from 5 minutes and no later than 10 minutes. If any lines do appear after 10 minutes, it is still a negative result and must be disregarded. If you read the test sooner than 5 minutes, it may also be inaccurate as it has not had enough time to work.

So, having explained the actual procedure, I would therefore advise you to repeat the test on an early morning and take the reading after 5 minutes or a blood hCG test can also be thought off for the confirmation.

Hope to have answered your query.

Best of luck.
