Home Pregnancy Tests 101

How it works: The e.p.t. design is a midstream test stick with an absorbent tip. The tip of the test stick is placed in the urine stream for at least five seconds in order to achieve accurate results. (Tip: Be sure to lay the test stick flat while awaiting the results.) The e.p.t. brand also offers a digital test. Much like Clearblue Easy, the test will show a "pregnant" or "not pregnant" notation upon completion.

When to take it: You can take the e.p.t. test up to four days before you expect to begin your period.

Result time: Test results are achieved in two minutes.

Medical Interactions: Medications that contain the pregnancy hormone hCG can affect the test. Testing too soon after administration of fertility drugs may give a false positive result. Rare medical conditions may also affect the outcome. Alcohol, pain killers, antibiotics, and birth control pills shouldn't affect the results.

Detects 40 miu of hCG.
