Missed periods on 8th April, took
Beta hcg test after 1 month (9-10th May around).
The beta serum level was 0.100 mIU/ML (ECLIA METHOD) from one lab and 1.2 mIU/mL (CMIA METHOD) from other lab, and they didnt asked for Last menstural date.
Why there is this difference ?
Was there any need to tell the lab about the last menstural date or can get it done any time ?
Are these results reliable or should go for another test ?
