Final answer:
To process the tests, the phlebotomist should obtain the necessary materials, perform a venipuncture for the WBC differential and glucose tests, and perform a capillary stick for the testosterone test.
Step-by-step explanation:
In order to process the WBC differential test, testosterone test, and glucose test, the phlebotomist should take the following actions:
- Obtain a test card, one patient serum sample, and a bottle of test reagent from their instructor.
- Perform a venipuncture on the patient's arm to collect a blood sample for the WBC differential test and glucose test.
- Perform a capillary stick on the patient's finger, earlobe, or heel to collect a small quantity of blood for the testosterone test.
After collection, the blood samples may be analyzed by medical laboratories to obtain the test results.
