Q: i had a quantitative hcg test done and my results were <1. what does that mean? i had it done 3 weeks and 2 days after intercourse.

U r NOT pregnant: This long after intercourse the ball of cells would have implanted in the uterine wall and have been pumping out ever increasing amounts of human chorionic gonadotrophin. The fact that the assay could not even detect even 1 unit implies that you have no functioning placenta growing - i.e. no pregnancy!

Q: i tested positive for pregnancy. a quantitative hcg test at 3w6d since lmp showed a level of 40. 5 days later my hcg was 120. is this increase too low?

Wide variation: There is wide variation in HCG levels in normal pregnancies. Your levels are within normal limits. See this site for more info. http://americanpregnancy.org/while-pregnant/hcg-levels/

Q: i had a quantitative hcg test done on 1-7-16. it was 8. that same day i began spotting. i believed i was experiencing a miscarriage. today is was13?

Need to repeat: Had you been pregnant with a healthy embryo, HCG level would have increased two fold over two days. It would be prudent to repeat the HCG levels. If you get abdominal pain, go to the emergency room of a hospital to rule out ectopic pregnancy.

Q: i got a result of <1.0 miu on a quantitative hcg test at 5/6 dpo? was it too soon or am i just not pregnant? when dpo should quantitative be done?

Too soon: Blood tests can detect pregnancy as early as 7 days following ovulation. However, if negative they should be repeated if the menstrual period is missed.

Q: what are quantitative hcg blood tests?

HCG levels.: The quantitative HCG is a measurement of the amount of pregnancy hormone in the blood. A qualitative HCG is simply a test to detect the presence of the pregnancy hormone - it does not indicate how much hormone is present, which relates to how advanced a pregnancy may be. The urine pregnancy test is qualitative - a blood test can be either qualitative or quantitative.

Q: what are reasons for false negative for a quantitative beta hcg test?

False negatives: All lab tests have a certain percentages of false negatives and positives.

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

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.

Q: when should i take blood quantitative beta hcg test after intercourse/sex?is it accurate enough if i do that 2 weeks after intercourse/sex?

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.

Q: would a quantitative blood pregnancy test result of less than 0.5 hcg be accurate at 5 weeks or is it too early?

Quants: Are accurate levels early that is why they are followed if the viability of the pregnancy is in question.

Q: hi, i did a beta hcg quantitative serum test once 39 days after sex and it came back negative 1.2 and took a home pregnancy test a week after, it came back negative too. is it accurate? should i worry about cryptic pregnancy?

: You did not state but I assume you has missed your period for at least one month (39 - 14 + 7). Ectopic pregnancy or normal pregnancy is ruled out with two negative tests, blood and urine, presumably on day 25th and 32nd after missed period.
