no a normal cbc will not tell you if you have active syphilis or not but there are many sensitive tests that your doctor can order to answer that trouble syphilis fear. unfortunately i do not have enough medical history about you or have the ability to delve into your clinical case to discuss the significance of a normal or abnormal cbc as it relates to you. you will need to address this with your medical provider -- someone who has the ability to correlate any lab findings with your history and physical examination results.
does a normal cbc indicate no bacterial infection such as active syphilis? . visited doctor w/103 fever full body somewhat itchy rash. cbc: normal. dx: viral infection rx: rest and fluids. two days later added symptom of sore throat. new cbc also normal; in fact identical. rash now covers all my body except penis and armpits. went home to rest. symptoms fading fever is gone and i am feeling better. but i can't help but wonder if syphilis "the great imitator" could be a culprit or would that have caused my cbc to spike with an active infection? thank you!
