Can we defer/omit a type and screen blood test for pregnant women who know their blood type?
Current clinical practice in many emergency departments (EDs) includes checking a type and screen blood test (T&S) for Rhesus (Rh) status on all pregnant patients presenting with vaginal bleeding or abdominal pain. The test is expensive, and awaiting results may delay disposition. ⋯ Pregnant women reporting that "yes, definitely" they know their blood type, are reliable. Deferring T&S testing test may be reasonable.
