How accurate is a first response pregnancy test at 2 weeks late for a period?

Accurate: If you did the test correctly at two weeks after a missed period and it was negative, you are very unlikely to be pregnant. You may repeat the test in 3-4 days. (your profile says you are a 19 year male) Use first morning urine and follow the instructions for the test carefully. If you do not wish to be pregnant, use contraception all the time, every time. You may consider implanted contraceptive, or IUD. Practice safe sex. Get HPV vaccine. ...Read more

Is a first response early result pregnancy test more accurate then a dr.S office urine test? My home pregnancy test was pos but doc office was neg!

Not likely.: No test is 100% accurate, unfortunately. I'd suggest waiting a week, repeating the home test, and if it's still positive, going back to your doctor's. If the doctor's office urine test is still negative, your doctor can order a blood test for pregnancy, which is more accurate. ...Read more

How common is a false negative quant blood pregnant test 3 weeks after a missed period?  And what would cause the false negative?

Not often: The quant HCG is very accurate. Knowing when you ovulated is more difficult. Repeat the quant test a few days later just to be sure you didn't ovulate later than expected. You could always just repeat a urine pregnancy test. This is very accurate as well especially when using the urine from your first void of the morning as this is often more concentrated. ...Read more
