A blood test for total hCG is used to diagnose pregnancy early when the test strip is not yet able to determine the result. In the absence of pathologies, the hormone level in the first weeks of pregnancy doubles every 2 days, the maximum is reached by 10-11 weeks.
It is recommended to conduct the study no earlier than 3-6 days of delay in menstruation in order to avoid false negative results. In case of questionable results, the test should be performed twice with an interval of 2-3 days. When determining the completeness of the removal of an ectopic pregnancy or abortion, a test for hCG is performed 1-2 days after the operation, to exclude a false positive result.
The study is carried out in the morning on an empty stomach. At least 8 hours should pass from the last meal.
