Your blood test compares your measured values against a reference range — the values seen in healthy people. LabDecode explains each result in plain English: what the test measures, whether your value is normal, high, or low, what commonly causes abnormal results, and when it's worth following up with your doctor. Enter your value into our Lab Report Decoder for an instant explanation.
Yes. Our reference ranges are aligned with Quest Diagnostics, LabCorp, and ARUP — the three laboratories most Americans use. We use US-standard units (mg/dL, mEq/L, g/dL). Note that your own lab report prints the specific reference range your lab used, and that range always takes priority over any general range.
No. LabDecode never stores, transmits, or shares your lab values. Every calculation in our tools runs entirely in your browser. We designed the site to be HIPAA-aligned by default — your health data never leaves your device.
