Tips For Using HPT's

What kind of test should you use? All Home Pregnancy Tests (HPT) are not created equally. Some are much more sensitive than others (test for a smaller amount of hCG) and you should be aware of this before you go shopping for an HPT. The more sensitive the test, the more likely you will be able to get a positive if you are pregnant. Many women on the WebMD boards have had good success with the Equate brand HPT, retailed by Wal-Mart. Others that I see mentioned frequently are First Response Early Results and Answer Quick and Simple (these companies also sell less sensitive tests, so be sure to read the labels carefully and check to see these are the ones that can be used before a missed period). If you are on a tight budget, you may wish to try looking at the local Dollar Tree or Dollar General as they have some tests for $1 that are actually sensitive to 25 mIU but you must pee in a cup and use an enclosed dropper to deposit your urine into the test, as opposed to holding the test stick in your urine stream. See this link for more information on test sensitivity:

When should you test? This is a question with no concrete answer. Women make hCG at different rates after becoming pregnant. Also, the fertilized eggs don’t all implant on the same number of days past ovulation. These things directly affect how much of the hormone hCG will be present in your urine if you are pregnant. It seems most women get their BFP at 10 – 14 days past ovulation when using sensitive tests (25 mIU or better). Depending on the length of your luteal phase, this may be a few days before you expect your period, or even a few days after you expect your period. It takes some women longer to get a positive test though. If you are worried that you might not cope well with a BFN, you should wait until you are sure you are late to test.

Most tests now say that you can use them any time of day. This is true, but you have the best chances of getting a BFP if you use your first morning urine (FMU), particularly if you are not even late yet.

Read the instructions. Tests have a time limit to read valid results. You might wish to set a timer so you know when to read the test results. You are also supposed to get the right amount of urine on the test, so read how long to hold the stick in your urine stream, or how long to dip it in urine. Read all of the instructions with the test carefully and follow them to have the best chance for a valid test result.

The test line should be in color for a positive result – usually pink in the US, but some tests use blue lines. A grayish line that looks like a shadow or an indentation is probably not a positive result.

There is a great FAQ section about HPT at this site:

What if you get a BFN? You may have tested too early. If you have still not gotten your period 2-3 days later you might wish to re-test if you are confident you are late. If you are not sure if you are late, you may want to test once a week so as not to keep wasting money on tests. If you have consistent cycle lengths and get to be 2 weeks late or more and are still getting negative test results, you may wish to call your doctor for some advice and possibly a blood test.
