Anyone know anything about free HCG levels-What is the normal level in pregnancy at 13 weeks?
Levels of hCG in pregnancy Human Chorionic Ganadotropin (hCG) is a hormone that can be detected in the urine and blood of humans. This hormone increases during pregnancy so it is common to measure the rise in level using Home Pregnancy Tests ( or HPTs, which measure hCG levels in the urine) or a hCG Beta test (which measures hCG levels in the blood serum). The hCG Beta is much more sensitive then the Home Pregnancy Test and you can usually get a positive result much earlier with a blood test than with the HPTs. Usually the reference values for hCG Beta are as follows: Men: less than 5.0 mIU/ml – Normal Women: Non -pregnant – less than 5.0 mIU/ml – Negative/normal *Borderline – Between 5.0 to 25.0 mIU/ml (you could be pregnant) *Positive – Higher than 25.0 mIU/ml (*) These are values within the first week and few days after conception When you are pregnant the level of hCG increases and usually doubles every two to three days. It then reaches a maximum level by the second or third month
