What this test is
This test involves drinking a lactose-containing solution and then having blood samples taken at timed intervals. It measures changes in blood glucose and may also track symptoms, because lactose normally breaks down into simpler sugars that raise glucose. A clinician uses the pattern to help evaluate possible lactose intolerance.
What it measures
- Fasting blood glucose — starting glucose level before the lactose drink
- Blood glucose after lactose — timed glucose readings after drinking the lactose solution
- Change in blood glucose — rise or lack of rise compared with the fasting level
- Symptoms during test — bloating, gas, cramping, or diarrhea reported after the drink
What the test involves
You drink a measured lactose solution after a fasting period, and a healthcare professional collects blood samples at set times afterward. The samples are usually drawn from a vein in the arm with a standard blood draw.
Why it is often ordered
A clinician may order this test when someone reports bloating, gas, diarrhea, or cramping after consuming dairy products. It can help distinguish lactose intolerance from other digestive issues and guide further discussion.
Preparation
The collection lab will provide specific instructions, which often include fasting for a certain number of hours before the test. Follow those instructions exactly, and ask the lab about any medications or foods to avoid.
How results are reported
Results are typically reported as blood glucose levels at each time point along with any symptoms observed during the test. Reference ranges and interpretation vary by laboratory, so the ordering clinician reviews the pattern in context.
Before you go
- Whether fasting is required and for how long
- Which medications or supplements may affect the test
- Whether symptoms during the test should be recorded and shared
