## How to Convert Blood Test Units

Blood test results can be reported in different measurement units depending on the country, laboratory, or healthcare system. The two main systems are **conventional units** (commonly used in the United States) and **SI units** (Système International, used in most other countries). This can make it confusing to compare results from different labs or understand values from international medical literature.

### Why Do Different Countries Use Different Units?

The United States primarily uses conventional units such as mg/dL (milligrams per deciliter) and ng/dL (nanograms per deciliter). Most of Europe, Australia, Canada, and the rest of the world use SI units such as mmol/L (millimoles per liter) and nmol/L (nanomoles per liter). The SI system was adopted internationally in the 1970s to standardize scientific measurement, but the US medical system largely retained the older conventional system.

This means a glucose reading of **100 mg/dL** in the US is the same as **5.55 mmol/L** in Europe. Both values are identical — just expressed differently.

### Common Blood Test Unit Conversions

| Biomarker | Conventional Unit | SI Unit | Multiply by |

| Glucose | mg/dL | mmol/L | 0.0555 |
| Total Cholesterol | mg/dL | mmol/L | 0.0259 |
| LDL Cholesterol | mg/dL | mmol/L | 0.0259 |
| HDL Cholesterol | mg/dL | mmol/L | 0.0259 |
| Triglycerides | mg/dL | mmol/L | 0.0113 |
| Creatinine | mg/dL | µmol/L | 88.4 |
| Uric Acid | mg/dL | µmol/L | 59.48 |
| Bilirubin (Total) | mg/dL | µmol/L | 17.1 |

| Hemoglobin | g/dL | g/L | 10 |

### How Unit Conversion Works

Each biomarker has a specific **conversion factor** based on its molecular weight. To convert from conventional units to SI units, you multiply by the conversion factor. To convert back, you divide by it. For example:

- **Glucose:** 100 mg/dL × 0.0555 = 5.55 mmol/L
- **Total Cholesterol:** 200 mg/dL × 0.0259 = 5.18 mmol/L
- **Creatinine:** 1.0 mg/dL × 88.4 = 88.4 µmol/L
- **Testosterone:** 500 ng/dL × 0.0347 = 17.35 nmol/L

### Tips for Comparing Blood Test Results

- Always check the units printed on your lab report before comparing values with reference ranges or past results.
- When comparing results from different labs or countries, convert to the same unit system first.
- Some biomarkers (like HbA1c or TSH) use the same units worldwide, so no conversion is needed.
- If in doubt, ask your healthcare provider to clarify which units your results are in.
