Answer

In a patient with associated vaginal bleeding, the hematocrit may be normal even when the patient has obvious hypovolemia on examination (eg, positive orthostasis or tachycardia), especially if hemorrhage started within minutes to hours of presentation. [28] Moreover, the EIA and DNA probe tests for gonorrhea and chlamydia have varying sensitivities, ranging from 86% to 93%. [28]
