Time to Test |
Normal Values |
What value means |
Triglycerides (TG) |
8-16 hours fasting |
< 200 mg/dl |
Borderline high is 200-400, high is 400-1000, and very high is >1000. Elevated levels are a risk factor for coronary artery disease. |
Cholesterol Total |
8-16 hours fasting |
< 200 mg/dl |
A level of 200-239 is borderline high, and a level 240+ is high. Increased levels are associated with increased risk of heart disease. |
low-density lipoprotein cholesterol (LDL) |
8-16 hours fasting |
< 160 mg/dl |
This is the "bad" cholesterol. In someone with one risk factor for heart disease, < 160 is recommended, with 2 risk factors < 130, and those with documented coronary heart disease the target is < 100 |
high-density lipoprotein cholesterol (HDL) |
8-16 hours fasting |
> 34 mg/dl |
This is the "good" cholesterol which may be increased through a healthy diet and exercise. The HDL level is usually estimated by taking total cholesterol and subtracting LDL, rather than by direct measure. |
C-peptide |
8-16 hours fasting |
0.5 to 4.0 ng/ml |
Levels increase with insulin production. |
Creatinine |
|
< 1.4 mg/dl |
Levels 1.4 mg/dl and higher may indicate renal (kidney) disease or renal dysfunction. |
