How does a home pregnancy test work?

My friend recently used a home pregnancy test, and it got me thinking. I'm curious about the science behind it. How do these tests actually detect pregnancy just from a urine sample?

The kit has a strip that detects a hormone called hCG in your urine, which is only present during pregnancy. Always use the very first urine of the morning for the most accurate result, and if you get a positive, see a gynaecologist for a proper scan.

It's very simple. You just put a few drops of your morning urine on the slot in the card. If the hCG hormone is present, you will see two pink lines. I always advise young moms to wait a few days after a missed period before testing.

It works by checking for the pregnancy hormone in urine. But as someone with PCOS, my cycles are very irregular and hormone levels can be tricky, sometimes leading to confusion. It's best to confirm with a doctor's blood test to be absolutely sure.

It's a basic chemical reaction strip that reacts to hCG hormone levels. Just buy any standard kit from the chemist, follow the instructions on the box, and you get the result in 3 minutes. Simple as that.

It detects hCG in urine. However, cheap or expired kits can give false negatives or faint lines which confuse people. Don't rely blindly on home kit results if you have symptoms; verify it with a proper lab blood test and a doctor's consultation.

Those little plastic strips just look for the pregnancy hormone. Back in our day, we had to wait and go to labs, but now you get the mini-heart attack or joy right in your bathroom in two minutes. Technology has made things so fast!
