Hello doctor, I had a sudden hearing loss twice and because it happened twice, I was sent for a plethora of blood tests. My ANA was negative but I noticed two markers out of range. I was wondering if you could give any insight into these blood test results?
Hello. I went through your post and investigations (attachment removed to protect patient identity), there are two things which I presume you think are abnormal. CK (creatine kinase), it is an enzyme produced by heart muscle and skeletal muscle. So, is elevated in people with muscle or heart disease but low levels have no significance and are common in people with a sedentary lifestyle who do not exert much. Anti-histone antibodies are seen in people with drug-induced lupus so if one does not have other features of lupus as in your case the hearing loss is not a criterion for lupus (ACR criteria for SLE). It has little or no importance. I think there is a possibility of Meniere's disease for which you should get investigated that can cause sudden temporary hearing loss.
