She might have been lying about having a blood test at a doctor's. Modern home pregnancy test are very reliable, even when used the first day a period is missed, or when taken with urine that isn't her first of the day. It sound pretty fishy. Why bother to do a home pregnancy test when she simply could bring her boyfriend to the doctor's office to have him/her tell her boyfriend the results? I really hope she isn't pregnant. She's not married, her boyfriend doesn't trust her, and she isn't smart enough to use condoms.

The pregnacy test detects Hcg in the urine. The urine is less concentrated than the blood. That's why they say to take it early in the morning. It takes time for the body to secrete enough of the hormone to spill over into the urine, thus the urine test will be negative, and the blood test positive.

Blood tests are far more sensitive than urine tests are. She should assume she is pregnant, or ask the Dr. to retest if she thinks she might not be. If it was just 1 home test, it may have been faulty.
Unless she is lying to you both.

The blood test is more sensative.

Maybe she took the first one too soon. You have to give your body a chance to build up the hormone that indicates pregnancy.

I don't know for sure, but I think blood tests are more accurate.

your friend might have not taken the test correctly. it depends on the time of day, or it depends on amount of hormones in urine. the same happened to me years ago
