Does drinking glucose powder affect blood test results?

In general, whether drinking glucose powder affects blood test results depends on the specific circumstances—it may have no effect, or it could have an impact. The details are as follows:

1. No effect

If the blood test is for routine liver and kidney function, consuming glucose powder typically has no effect. It generally does not interfere with test results or negatively affect health.

2. With effect

If the patient's blood test aims to measure blood glucose levels, taking glucose powder may cause elevated blood sugar, thereby affecting the accuracy of the test results.

It is recommended that patients remain in a fasting state before blood tests and avoid eating or drinking anything to prevent inaccurate results, which could affect the doctor's assessment and delay treatment. If any discomfort occurs during blood collection, patients should promptly inform the doctor to avoid adverse reactions.
