Let’s explore “Specific gravity — lab reference”

Ask your clinician to use the exact assay cutoff. Helpful in selected Graves disease questions.

This is not a general thyroid wellness target. It may be used for follow-up after certain thyroid conditions, alongside thyroid anatomy and antibody results.

No universal wellness target. Ask your clinician to read this result with B12, folate, B6, kidney, thyroid, genetics, and medications.

Can help distinguish iron deficiency from inflammation; use performing-lab interval.

No universal interval across methods. Record exact performing-lab method and range.

Spot urine is useful mainly for populations; individual status requires careful collection and interpretation.

Ask your clinician to read this result with lipid level, supplementation, and performing-lab interval.

Sample handling and test methods can change a cytokine result. Compare it with the exact range from your lab and ask why the test was ordered.

Mayo example age 20-24: M 5.25-20.7; F <0.13-1.08. Declines with age and is method-dependent.

Depends on total testosterone, SHBG, albumin, calculation, and assay.

Female phase detail is on the next section. Exogenous progesterone route/timing matters.

Ask your clinician to read this result with testosterone or estradiol, FSH, cycle phase, and pituitary context.
