Metabolic Health

Metabolism is your body’s way of chemically processing sugar and fat for use throughout the body as energy. An optimal metabolism supports healthy weight control and energy levels, while a dysfunctional metabolism can lead to undesired fluctuations in weight and fatigue or hyperactivity.

Free Androgen Index

Optimal range: 0 - 6.6 u

FREE T3

Optimal range: 2.6 - 5.7 pmol/L

Free T4

Optimal range: 0.7 - 1.53 ng/dL

Free testosterone

Optimal range: 8.7 - 25.1 pg/mL

Testosterone is the primary male sex hormone in humans. A healthcare professional may order a free testosterone blood test if you’re experiencing sexual problems or a secondary condition, like hyperthyroidism, is suspected.

Free Thyroxine

Optimal range: 0.6 - 1.2 ng/dL

Glucose

Optimal range: 3.6075 - 5.55 mmol/L

Glucose is a simple sugar used as a primary energy source in our bodies. Blood glucose tests are most frequently ordered for the diagnoses and monitoring of diabetes.

Glutamic Acid Decarboxylase

Optimal range: 0 - 0.5 nmol/L

Hemoglobin A1c (HbA1c)

Optimal range: 4.8 - 5.6 %

Homocysteine

Optimal range: 0 - 10 µmol/L

Homocysteine is an amino acid that requires vitamin B12 and folate to be used by our bodies. As such, homocysteine blood tests are often ordered to identify vitamin B12 / folate deficiency.  Rarely, an abnormally high level of homocysteine indicates a rare genetic disorder called homocystinuria.

IGF-1

Optimal range: 114 - 492 ng/dL

IGF-1 measurements are adjusted for age because levels tend to decrease as you get older.

Results of IGF-1 are given in nanograms per milliliter (ng/mL). Normal ranges by age are:

- 182 to 780 ng/mL for ages 16 to 24

- 114 to 492 ng/mL for ages 25 to 39

- 90 to 360 ng/mL for ages 40 to 54

- 71 to 290 ng/mL for people 55 and older

Reverse T3, Serum

Optimal range: 9.2 - 24.1 ng/dL

SHBG

Optimal range: 10 - 33 nmol/L

Sex hormone-binding globulin is a protein that binds primarily to testosterone, making it biologically unusable by our bodies. For this reason, an abnormal level of SHBG indicates that too much or too little testosterone is present in the tissues. In men, this can cause sexual issues like erectile dysfunction or infertility. In women, it can cause irregular menstruation or excess facial hair growth. A healthcare professional may order a SHBG test when total testosterone levels do not fit with one or more of the above-mentioned symptoms.

Testosterone

Optimal range: 298 - 1043 ng/dL

Testosterone is the primary male sex hormone in humans. Testosterone blood tests can assess testosterone that is bound to a protein, testosterone that is free in the blood, or both. A healthcare professional may order any of these tests if you’re experiencing sexual or hormonal problems.

Testosterone (Female/Child)

Optimal range: 0 - 1.7 nmol/L

Thyroglobulin Antibodies

Optimal range: 0 - 4 IU/ml

Thyroid-Stimulating Hormone (TSH)

Optimal range: 0.5 - 4.5 mIU/L

A thyroid-stimulating hormone (TSH) blood test is used to check for thyroid gland problems. TSH is produced when the hypothalamus releases a substance called thyrotropin-releasing hormone (TRH). TRH then triggers the pituitary gland to release TSH.

Thyroxine (T4)

Optimal range: 4.5 - 12 ug/dL

Total T3

Optimal range: 0.8 - 2 ng/mL

Triiodothyronine, Serum

Optimal range: 2 - 4.4 pg/mL
