I had to do a CBC blood test for something else and the results came today. Now im curious, can a normal blood count test like this show if someone is pregnant or not? just wondering how it works.
No, CBC checks blood counts like hemoglobin and platelets, not pregnancy. For pregnancy you need the beta hCG blood test or a urine kit. CBC is done during pregnancy but not to confirm it.
CBC and pregnancy test are different things. To confirm pregnancy, ask for hCG specifically. If you are unsure which test to do, your doctor or even the lab will guide you correctly.
