Early Home Pregnancy Tests - Do they Work? And HOW do they work?
Well, we have to go into a bit of biology here. You see, when you are pregnant, your body releases a hormone called human chorionic gonadotropin (HCG) these levels rise dramatically once conception has taken place (the embryo emplants into the uterus) this is why pregnancy can be detected in the blood a few days before a period is due.
USUALLY pregnancy can only be detected around the time of your period is due because of the hormone level that is needed to trigger a positive result in these home pregnancy tests. This is because standard pregnancy tests measure for results between 30-40mIU (this is the level of hormone) to make the test positive.
Early Home Pregnancy tests are weaker. Setting off a positive result if levels as low as 10mIU is detected. The theory being that HCG would not be in a woman's system if she is NOT pregnant. Therefore a false negative test is virtually impossible. (though there are anomalies as with all things)
So....DO they work?
In theory, yes. If you get two lines....you've got a little bean in your tummy that will change your life forever....or if there's just one line, you're not pregnant. Simples.
Or is it?
The problem is, they aren't entirely reliable. You CAN get a false positive, because there are some strange women out there (for reasons unknown to the baffled doctors) that do possess a small amount of HCG in their blood, EVEN when they are NOT pregnant. I have also know women to take a test, get a positive result and then proceed to have a period when they are due one. This is usually due to an early miscarriage that would not have been detected had they waited until they were due a period.
MY (UNPROFESSIONAL) OPINION
DON'T take a test a week before for your period. If you ARE pregnant, you will have a much stronger result if you wait AND you save yourself hearthache if you don't know whether you're period is a miscarriage or not.
Personally, I think home pregnancy tests should be free. Back in the old days they didn't exist and you had to go to the docs to find out if you're "with child". Now the health industry has created these great home tests (and they are great, I have used them and they DO give piece of mind, when used at the correct time) AND cash in on paranoid women who like to buy trolley loads and test every minute of the day! (You know who you are!) I think there should be a basic test (similar to the ones that you use at the doctors) that should be free to all women.
If you want something more hi-tech and in writing (like I did) Go for the Clearblue Digital and take ON THE DAY when your period is due. It's quick, easy and actually TELLS YOU "Pregnant" or "Not Pregnant" you wont be spending hours holding the stick up to the light and examining it from every angle, wondering if that tiny smudge is a line or not....
Summary: These are rubbish
