My hCG level was 229 at 4 weeks and at 4 weeks and 2 days it was 329 there was 36 hours between blood tests. Are tge numbers ok?

Not clear yet: The first number is very high, suggestive of twins. The second number did not rise as much as expected. So it is possible one one survived. It could be overall an abnormal pregnancy. It could be totally fine with a rise just now as much as expected. It will take another 10 days or so to figure out. ...Read more

Are blood tests for hCG levels always right after 1 month of having sex? Could it ever be a negative while it's positive my hCG levels were 0.375

Are blood tests for hCG levels always right after 1 month of having sex? Could it ever be a negative while it's positive my hCG levels were 0.375

Unclear question: There is wide variation in HCG levels in early pregnancy. A level of <5 units is not pregnant; level >25 units is pregnant and in between 5 and 25 needs retesting. See this site for more info. http://www.babymed.com/hcg-level-in-early-pregnancy. ...Read more

I had hCG blood test and it was a negative after 1 month of sex... How valid are blood tests? Can they ever tell me that i'm not pregnant when i'm not

Time & technique: Both urine and blood tests for HCG are very accurate in measuring hcg. It is better to do either test 4-5 days after a missed period. Negative pregnancy test done after one month of the last episode of sex is a good indication that the person is not pregnant. You should repeat the test 7-10 days later for an added measure. ...Read more
