I had my blood work done a few days ago and all the results came out within the normal range except for SERUM LDL CHOLESTEROL which registered 46.6 mg/dl. I understand the normal range is 100 to 120 mg/dl. I asked the doctor if this wasn't abnormal and he said it wasn't and congratulated me on the low LDL level. I can't quite believe this to be true. What's your take on this?
