Final answer:
Labs to be drawn in suspected ovarian torsion should include a CBC and a coagulation profile to identify any infection, anemia, or bleeding disorders, though the main diagnostic tool is imaging, such as an ultrasound with Doppler.
Step-by-step explanation:
In the case of suspected ovarian torsion, the labs that should be drawn include a complete blood count (CBC) and a coagulation profile. Options a), b), and d) suggest tests that are not primarily utilized to diagnose ovarian torsion. Ovarian torsion requires prompt diagnosis and management to prevent loss of the ovary due to ischemia. A CBC can indicate whether there's infection or anemia present, while coagulation tests can inform about any bleeding disorder that might complicate surgery if it is needed. However, the mainstay of diagnosis is through imaging studies such as an ultrasound with Doppler to assess blood flow to the ovaries.
