Now that you have (or have not) seen a couple of blue lines on a home pregnancy test, you may be asking yourself just how accurate are pee-on-a-stick home pregnancy tests, anyway?
1. Most pregnancy tests claim to be 99%+ accurate.2. Pregnancy tests should be taken in the morning, with the day's first urination. hCG, the marker detected in home pregnancy test is most concentrated in the urine at that point, increasing the likelihood for an accurate result.3. Take at least two home pregnancy tests several days apart. You're most likely to get an accurate result over the course of two or three tests spaced several days apart. This will help eliminate false negatives due to low hCG levels, and false positives due to faulty tests, improper use or other factors.4. The longer you wait to take a test, the more likely it will be accurate. Aim for 1 week after a missed period. Again, hCG levels are more likely to be at sufficiently detectable levels in the case of pregnancy.5. False negatives are more common than false positives. You're more likely to be told you're not pregnant when you really are, but false positives are also possible due to a number of factors.
