Let’s explore “Progesterone, follicular — lab reference”

Acute-phase reactant. Menstruation, menopause, inflammation, liver disease, and iron therapy matter.

<150 supports deficiency; 150-400 is often treated as borderline and may warrant MMA/homocysteine review.

<4.0 suggests deficiency. Recent intake or supplementation may raise serum values.

More specific for cellular B12 deficiency; kidney impairment can elevate.

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

Acute-phase reactant; used in hemolysis evaluation with LDH, bilirubin, and reticulocytes.

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

Interpret relative to hemoglobin, oxygenation, and kidney function.

<10 severe deficiency; 10-19 mild-moderate deficiency. Toxicity assessment requires clinical context.

Not a routine vitamin D status test. Ask your clinician to read this result with calcium, phosphorus, kidney function, and PTH.

Fasting and supplement abstention improve interpretability.

Recent supplementation can elevate; very high values may be clinically relevant.
