Pain and bleeding complicate 30% of pregnancies, raising concerns for viability. The objective is to evaluate the diagnostic characteristics of a single serum progesterone level in assessing pregnancy viability among symptomatic patients. ⋯ A single progesterone level provides a clinically useful prognostic information on pregnancy viability. More than nine out of ten patients with a level < 6.3 ng/mL (< 20.034 nmol/L) will be diagnosed with a non-viable pregnancy, and more than 90% of patients with a level ≥ 20-25 ng/mL (63.6-79.5 nmol/L) will have a viable pregnancy confirmed.
