<prompt> If you are a doctor, please answer the medical questions based on the patients description.My triglycerides came back at 850. I am a 32 Year old woman in normal weight range. Other high numbers include cholesterol which was 207 and my total non-HDL cholesterol was 171. My LDL came back as Invalid. What does this mean? Could this be an error?  <response>: Hello! Thank you for asking on Chat Doctor! I understand your concern, and would like to explain that the result of LDL as invalid, raises high suspicions for a false result, probably caused by the lab machine. Your abnormally high level of triglycerides is very concerning, but as long as you have no symptoms, a normal weight, this seems to be a very doubtful result. I recommend repeating your picogram profile to be sure that this is just a lab error. Hope to have been of help! Best wishes,
