Several months ago I wrote a little post about the Dollar Store.
If you missed the series, you can find it here:
Seems like that little Dollar Store post struck a chord with many of my readers and it's safe to say that that post went viral on pinterest.
One of the most talked about Dollar Store buys from my list has been the pregnancy tests.
I thought I would answer the question that I have gotten often,
"Should I buy a pregnancy test at the Dollar Store?"
Let's start by finding out how pregnancy tests work. Thanks to the lovely people at womenshealth.gov for this easy to understand answer.
All pregnancy tests work by detecting a certain hormone in the urine or blood that is only there when a woman is pregnant. This hormone is called human chorionic gonadotropin (kohr-ee-ON-ihk goh-NAD-uh-TROH-puhn), or hCG. It is also called the pregnancy hormone.
hCG is made when a fertilized egg implants in the uterus. The amount of hCG rapidly builds up in your body with each passing day you are pregnant.
So, pregnancy tests detect the hormone hCG in your urine, if you are pregnant, you get a positive result, if you are not pregnant, no hCG is detected, therefore, giving you a negative result. Sometimes, the test is taken too early, and there isn't enough hCG in your urine to detect a positive result. False negatives happen, false positive results however, are quite rare.
Some home pregnancy tests are more sensitive then others at detecting hCG in your urine stream. hCG is measured in mIU's, so I did a little research to see how sensitive each pregnancy on the market is. The lower the mIU's the more sensitive, therefore, the test will detect pregnancy earlier. Thank you to baby hopes for compiling this easy to read list.
