Tested with 2 lines but the test is not pregnant?

Question
Hello doctor,
My sister tested 2 lines up, then had blood clots in her abdomen, went to the hospital, tested for HCG and the result was pregnant, but the blood clot test was not pregnant. Now, my sister doesn't bleed anymore, the test still has 2 lines, but going to the transducer ultrasound, the ultrasound usually still doesn't show the pregnancy, it's been 1 month since the end of last month's period until now. So the doctor asked me to take a 2-bar test but the test is not pregnant? Thank you doctor.

Hello,
With the question “What is the test with 2 bars but the test is not pregnant? ", the doctor would like to answer as follows:
Your sister's case may have been pregnant before, after abdominal pain and blood clots, the pregnancy was miscarried, so the ultrasound did not show the gestational sac inside. uterine cavity and pathological examination when the gestational sac has completely aborted, there are no signs of pregnancy. However, a repeat pregnancy or an ectopic pregnancy cannot be ruled out. Your sister needs to go to a reputable medical facility to determine exactly what is wrong with her, from which to have appropriate treatment. If you still have questions about the 2-bar test but the test is not pregnant, you can go to the hospital of Vinmec Health System for further examination and advice. Thank you for trusting and sending questions to Vinmec. Wishing you lots of health.
