AST (Alternate Site Testing) means using a part of the body other than the fingertips to obtain blood for blood sugar testing. This may include taking a blood sample from anywhere other than the fingertips, including the palm, the upper forearm, the abdomen, the calf and the thigh.
Where can I test my blood sugar besides my fingers?
Your thumb is another option if you’re tired of using fingers. Other possible locations include the thigh, calf, upper arm, and forearm. However, sites other than your palm are recommended only if your blood sugar is stable at the time of testing.
Can alternative sites check blood sugar?
Alternate Site Testing (AST) is testing blood glucose in areas other than the fingertips. Alternate sites include the forearm, palms, legs, upper arm, and stomach. AST can be just as accurate as traditional testing at the fingertips if blood sugar is stable, but may not be if glucose is rising or falling quickly.
When should alternate site testing not be used to check blood glucose?
Though blood sugar testing is the only way to know for certain whether glucose levels are dropping, alternative site testing is not recommended for people who struggle with hypoglycemic awareness. 4 Discuss it with your healthcare provider before you do alternate site testing.
What should a nurse do when collecting specimens?

- Inform the patient of the reason for specimen collection;
- Explain the procedure;
- Assess the patient’s understanding;
Which is more accurate FreeStyle Libre vs finger stick?
Both finger prick glucometers and CGMs have some error margin. The gold standard for accuracy is a blood draw measurement and both finger sticks and CGMs have error margins (MARD) to that standard. Finger sticks tend to be in the range of 5-10% MARD, while the Libre has a MARD of about 9.4% over 14 days.
What is the most accurate way to check your blood sugar?
Some meters allow you to test in various spots on the body, but the fingertip is still the most accurate. It’s especially important to test the same place if you occasionally get results you find concerning. Testing different spots on the body, even one right after the other, can provide different results.

Why choose freestyle test strips?
• FreeStyle test strips kept in dessicant coated cannister to help keep cool and free of moisture. • Starts test only when enough blood has been applied to minimise result errors and reduce strip wastage. • Dual fill test strips for left or right handed sample application.
How to start using alternate sites for blood glucose testing?
How to start using alternate sites. For a meter to be approved for alternate-site testing by the US Food and Drug Administration (FDA), studies must show that the meter accurately measures blood glucose levels within 20% of a laboratory measurement using blood samples from alternative sites.
Are alternate-site blood tests more effective today?
Today’s meters, for the most part, require a much smaller blood sample than older meters, which makes alternate-site testing more feasible. “What led to success [in alternate-site testing],” says Horwitz, “is the ability to test a small volume of blood.
