Your Blood Test Report — Decoded
Getting your blood test results back can feel like reading a foreign language. This guide walks you through the most common tests — the CBC and basic metabolic panel — in plain English.
The Complete Blood Count (CBC)
The CBC counts and measures the different types of cells in your blood. It's the most commonly ordered test in medicine.
| Test | Normal Range | Low Means | High Means |
|---|
| WBC | 4.5–11.0 ×10³ | Viral infection | Bacterial infection |
| Hemoglobin | 12–17.5 g/dL | Anemia, fatigue | Dehydration |
| Platelets | 150–400 ×10³ | Bleeding risk | Clotting risk |
The Basic Metabolic Panel (BMP)
Glucose (70–99 mg/dL fasting): Elevated fasting glucose signals prediabetes (>100) or diabetes (>126). Creatinine (0.6–1.3 mg/dL): Elevated creatinine indicates reduced kidney function. Potassium (3.5–5.0 mEq/L): Abnormal potassium affects heart rhythm — both high and low are dangerous.
⚠️ Many common medications — including ibuprofen and some blood pressure drugs — can elevate creatinine. Always tell your doctor every OTC medication and supplement you take before blood tests.
Understanding the H and L Flags
Reference ranges represent the middle 95% of a healthy population — meaning 5% of completely healthy people will have at least one value outside the range. A single slightly abnormal value without symptoms is usually not a diagnosis. It's a data point that needs context.
