Which of the following is a CLIA waived test that can be performed by the medical assistant?
A. differential
B. chemical urinalysis
C. Gram stain analysis
D. crossmatch
Your response:
chemical urinalysis
Correct response:
chemical urinalysis
Rationale: A medical assistant can perform a chemical urinalysis test, which shows if the patient
has protein or glucose in their urine, but would require intervention by the primary care
provider. A chemical urinalysis can also tell what the specific gravity of the urine, meaning how
diluted or concentrated it is. The test is done with a small dipstick that changes color when it
comes into contact with urine. The medical assistant then compares the stick to a chart to see
what is in the urine and if anything is abnormal. A differential is done by a laboratory technician.
It is done by drawing blood and then placing the blood on a glass slide to look for any signs of
infection or anemia. A Gram stain analysis is also done in the lab under a microscope when a
bacterial or viral infection is suspected. Cross-matching is a test administered before a blood
transfusion to ensure the donor’s blood is compatible with the recipient. This test is performed
by a certified laboratory technologist.
The physician orders a random blood sugar on an adult patient newly diagnosed with diabetes
who is right hand dominant. The medical assistant notices inappropriate puncture markings on

A. "It’s best to use the outer edge of the middle or ring finger on your left hand when doing

sugar testing."
C. “Do not use your right hand when checking your blood sugar."
D. "It’s best to use the outer edge of the under-side of your big toe when performing
