Glucose test - blood
Alternate Names : Random blood sugar, Blood sugar level, Fasting blood sugar
Risks
Veins and arteries vary in size from one patient to another and from one side of the body to the other. Obtaining a blood sample from some people may be more difficult than from others. Other risks associated with having blood drawn are slight but may include: - Excessive bleeding
- Fainting or feeling light-headed
- Hematoma (blood accumulating under the skin)
- Infection (a slight risk any time the skin is broken)
Special Considerations
Many forms of severe stress (for example, trauma, stroke, heart attack, and surgery) can temporarily increase blood glucose levels. Drugs that can increase glucose measurements include the following: - Atypical antipsychotics, especially olanzapine
- Corticosteroids
- Diazoxide
- Intravenous dextrose
- Diuretics
- Epinephrine
- Estrogens
- Glucagon
- Isoniazid
- Lithium
- Phenothiazines
- Phenytoin
- Salicylates (see aspirin overdose)
- Triamterene
- Tricyclic antidepressants
Drugs that can decrease glucose measurements include the following: - Acetaminophen
- Alcohol
- Anabolic steroids
- Clofibrate
- Disopyramide
- Gemfibrozil
- Monoamine oxidase inhibitors (MAOIs)
- Pentamidine
- Sulfonylurea medications (such as glipizide, glyburide, and glimepiride)
