How soon can SureStep™ hCG be used?
SureStep™ hCG can detect hCG in urine at concentrations = 25 mIU/ml. On the first day of the missed period the level of hCG in the urine of a pregnant woman is expected to exceed 100 mIU/ml. In a normal pregnancy hCG can be detected in both urine and serum as early as 7 -10 days after conception. When testing before the period is due positive results can be relied upon however, some of these patients will go on to experience a loss of their early pregnancy and in these cases further testing will result in negative results. Negative results obtained when testing before the day of the expected period may be because the patient is not pregnant or the level of hormone may not yet be high enough to be detected.
