Question 1

what is the best time to take a quantitative serum beta hcg test?

Accepted Answer

3 wks after sex: There is no need to rush. A pregnancy test gives a reliable result 3 weeks after sex (3 wks after when conception might have occurred), or 1 week after missing a period. If done sooner, a positive result is likely real, but a negative result may be due to testing too soon, and thus lead to a repeat test. If a woman gets her normal regular period, then she is not pregnant, and a test isn't needed.

Question 2

is serum hcg test accurate at 14 days after intercourse?

Accepted Answer

: Most likely. About 9 days or so after conception will a serum HCG become positive, on average. However, not EVERYONE is average. Hope this helps.

Question 3

Accepted Answer

: Most likely not pregnqnt if test done correctly. But all tests have false negatives and false positives. Discuss with Dr and lab.

Question 6

14 days late for period. having yellow/brown stains w/ no odor 7 days ago but today had slight foul odor. have cramps. negative qualitative serum hcg test 49 days after sex. exposure. been 11 weeks and 4 days since. 2 mens (mar 12 d; apr 9d). preg?

Accepted Answer

: If the foul odor persists you should be checked for an infection but that has nothing to do with being pregnant. Your dates and timelines are not at all clear and even appear contradictory. If you had a negative serum HCG 49 days after your last sexual encounter then it is extremely unlikely that you are pregnant. If you are still concerned, do another test.

Question 7

hello, i been taking tylenol because i have the flu as well as an antiviral medicine. i have to take an hcg test. how long do i have to wait for that medication to leave my body?

Accepted Answer

Question 8

i wanted to know if there is hcg in flagyl/metronidazole 500mg. can this drug cause a false positive on a pregnancy test?

Accepted Answer

No + no: there is no hCG, and it will not cause false positives (or negatives.) Good wishes.

Question 9

does flagyl/metronidazole 500mg medication have hcg in it? can this drug cause a false positive pregnancy test?

Accepted Answer

No: There is no HCG in metronidazole and it does not cause a false positive pregnancy test. If your pregnancy test is positive, you are pregnant.

Question 10

does a hcg test serum at 6 months pregnant test positive?

Accepted Answer

: hCG or human chorionic gonadotropin is a hormone used to test for pregnancy by urine or serum . It can be detected as early as 6 days after ovulation or 8-10 days when the egg is transplanted. It is not a reliable test to determine gestational age, except in the first few weeks of pregnancy. hCG remains detectable until the birth of the fetus. It is also detected in testicular cancer
