12 entries
Erythropoietin — lab reference
Interpret relative to hemoglobin, oxygenation, and kidney function.
Iron Status, Anemia Workup, and Methylation-Related MarkersFerritin — lab reference
Acute-phase reactant. Menstruation, menopause, inflammation, liver disease, and iron therapy matter.
Iron Status, Anemia Workup, and Methylation-Related MarkersFolate, serum — lab reference
<4.0 suggests deficiency. Recent intake or supplementation may raise serum values.
Iron Status, Anemia Workup, and Methylation-Related MarkersHaptoglobin — lab reference
Acute-phase reactant; used in hemolysis evaluation with LDH, bilirubin, and reticulocytes.
Iron Status, Anemia Workup, and Methylation-Related MarkersHomocysteine, total — lab reference
No universal wellness target. Interpret with B12, folate, B6, kidney, thyroid, genetics, and medications.
Iron Status, Anemia Workup, and Methylation-Related MarkersMethylmalonic acid — lab reference
More specific for cellular B12 deficiency; kidney impairment can elevate.
Iron Status, Anemia Workup, and Methylation-Related MarkersSerum iron — lab reference
Morning fasting collection is preferred when practical. Day-to-day variation is substantial.
Iron Status, Anemia Workup, and Methylation-Related MarkersSoluble transferrin receptor — lab reference
Can help distinguish iron deficiency from inflammation; use performing-lab interval.
Iron Status, Anemia Workup, and Methylation-Related MarkersTotal iron-binding capacity (TIBC) — lab reference
Interpret with iron, transferrin saturation, and ferritin.
Iron Status, Anemia Workup, and Methylation-Related MarkersTransferrin — lab reference
Negative acute-phase reactant; affected by liver function and nutrition.
Iron Status, Anemia Workup, and Methylation-Related MarkersTransferrin saturation — lab reference
Calculated from iron and TIBC. Fasting and timing improve consistency.
Iron Status, Anemia Workup, and Methylation-Related MarkersVitamin B12 — lab reference
<150 supports deficiency; 150-400 is often treated as borderline and may warrant MMA/homocysteine review.
