Patient Friendly Summary

Ketones are exhaust fumes from fat-burning. After a skipped meal they mean little; in a person with diabetes and very high sugar they are a red flag needing same-day medical attention.

What this test means

Ketones appear when the body burns fat instead of sugar — from fasting, vomiting, strict dieting, or seriously uncontrolled diabetes.

Why it is done

It is done in diabetes with very high sugars or illness, in children with vomiting, and during fasting-related evaluations.

Understanding your value

If your value is high

Ketones with high blood sugar may suggest diabetic ketoacidosis, which needs urgent medical care. Without diabetes, mild ketones often just reflect fasting or vomiting.

If your value is low

Absent ketones are normal.

About the normal range

Reported as nil, trace, small, moderate, or large. Context decides seriousness — the same 'trace' means different things in different situations.

When to consult a doctor

If you have diabetes and find moderate or large ketones with high sugar, nausea, or heavy breathing, seek medical care promptly.
