The normal serum 1,5-anhydroglucitol (1,5‑AG) range is approximately 10–30 µg/mL (micrograms per milliliter). Values above this typically indicate no recent significant hyperglycemia; lower values reflect recent postprandial hyperglycemia and glucose excursions over the prior 1–2 weeks. Interpret alongside HbA1c and clinical context, as lab reference ranges and units may vary slightly.

1,5-Anhydroglucitol (1,5‑AG) is a blood marker used in diabetes to detect recent hyperglycaemia and glycaemic variability. High blood glucose causes renal glucose loss that blocks reabsorption of 1,5‑AG, lowering its serum concentration. Because it reflects glycaemic excursions over the prior 1–2 weeks, it complements HbA1c for identifying postprandial spikes and short-term control.

A HbA1c of 5% means your average blood glucose over the past two to three months is about 97 mg/dL (5.4 mmol/L). This falls in the normal, non‑diabetic range and indicates low diabetes risk or good glycaemic control. It doesn’t rule out occasional highs or lows; discuss testing and any symptoms with your clinician.

GlycoMark (1,5‑anhydroglucitol) is reported in µg/mL; normal values are generally ≥10 µg/mL, with many labs using a reference range around 10–30 µg/mL. Lower GlycoMark indicates recent short‑term hyperglycemia and postprandial glucose spikes — values roughly below 6–10 µg/mL suggest significant glycemic excursions. Interpret results alongside HbA1c and clinical context with your clinician.

Prediabetes is defined by any of these: fasting plasma glucose 100–125 mg/dL (5.6–6.9 mmol/L); HbA1c 5.7–6.4% (39–46 mmol/mol); or 2‑hour oral glucose tolerance test 140–199 mg/dL (7.8–11.0 mmol/L). Values below these ranges are normal; higher values indicate diabetes. People with overweight, family history, high blood pressure, or high cholesterol should test more often and discuss prevention with a clinician.

The normal right ventricular stroke work index (RVSWI) is generally 5–10 g·m/m^2 per beat. RVSWI = (mean pulmonary artery pressure − right atrial pressure) × stroke volume index × 0.0136. Values below this range suggest RV dysfunction; higher values indicate increased RV workload from pulmonary hypertension or pressure/volume overload. Interpret alongside clinical context and other hemodynamic data.
