Fasting glucose: ideally between 70 and 85 mg/dL as long as you are not symptomatic (i.e., you have no issues with hypoglycemia or reactive hypoglycemia).

Triglycerides: below 100 mg/dL.

Fasting insulin: below 10 IU/mL (and ideally closer to 5 IU/mL or below).

Fasting leptin: ideally between 4 and 6 ng/dL. 

Total cholesterol: roughly between 225 and 240 mg/dL. (The conventional medical standards are arbitrary and relative.

Postmenopausal women, for instance, tend to do better with high levels.) if your level is higher than this, it may be an indication that there is something else happening for which the extra cholesterol is necessary. Be happy that the cholesterol is doing its job, then dig deeper with the help of a qualified healthcare provider well-schooled in functional medicine to get to the bottom of what is generating your apparent increased cholesterol need.

HDL: ideally between 55 and 75 mg/dL. Higher may imply either a genetic tendency or some hidden nonspecific source of inflammation.

Hgb A1C: between 4.7 and 5.4% is a good range.

Uric acid: between 3.2 and 5.5 for women and 3.7 and 6.0 for men.

TSH: between 1.8 and 3.0

TPO antibodies: below the upper reference threshold. (Elevated levels imply thyroid autoimmunity.)

Anti-thyroglobulin antibodies: below the upper reference threshold. (Elevated levels imply thyroid autoimmunity.)

Homocysteine: below 6.0µmol/L

CRPhs: between 0 and 3 mg/L (and preferably not over 1.0 mg/L). 

Fibrinogen: between 193 and 423 mg/dL. 

BUN: between 13 and 18 mg/dL.

SGOT (AST): between 10 and 26 IU/L. 

SGPT (ALT): between 10 and 26 IU/L. 

GGTP: between 10 and 26 IU/L.
