Hello welcome to HCM. HCG
is detectable in the blood serum of approximately 5% of pregnant women by 8 days after conception, and in virtually all the rest by 11 days. HCG rises progressively from conception. A blood serum level of less than 5 mIU/ml (5 IU/L) can be considered negative and anything above 25 mIU/ml (25 IU/L) positive for pregnancy
. If you are unsure, repeat the test in two days to see if there is an upward trend, which indicates pregnancy. So in case you might need to repeat the test. Wish you good health.
