X-Ray Report Language: Common Terms DecodedWhat 'No Acute Abnormality' Means on a Scan
Imaging
If your scan report says 'no acute abnormality', that is generally reassuring — no urgent or recent findings were identified. But it doesn't always mean the scan is completely normal.
What 'No Acute Abnormality' Means on a ScanWhat "Within Normal Limits" Really Means
Lab Tests
"Within normal limits" (WNL) usually means a measurement falls inside the expected range — but it does not mean every aspect of your health is perfect, every condition has been excluded, or persistent symptoms should be ignored.
What "Within Normal Limits" Really MeansWhat Does "Unremarkable" Mean on a Scan?
Imaging

Lab Tests
ALT is the most specific blood marker for liver cell damage. A raised result doesn't automatically mean serious liver disease — context, degree of elevation, and other markers all matter.
High ALT: What a Raised Result MeansHigh Bilirubin: What an Elevated Result Means
Lab Tests
Bilirubin is a yellow pigment produced when old red blood cells break down. A raised level doesn't always indicate serious liver disease — in many people it's caused by Gilbert's syndrome, a harmless inherited condition.
High Bilirubin: What an Elevated Result MeansHigh CRP: What It Means and What to Do Next
Lab Tests
