CPT (Certified Phlebotomy Technician) Practice Exam

For a ROYAL BLUE tube, what test is typically run, which anticoagulant is used, and to which lab section is it sent?

1. Toxicology levels, sodium heparin, toxicology

2. Blood typing, SST, blood bank

3. Glucose GTT, potassium oxalate, chemistry

4. PK, K2EDTA, chemistry

The correct answer is: Toxicology levels, sodium heparin, toxicology

For a ROYAL BLUE tube, the test that is typically run is toxicology levels. The anticoagulant used is sodium heparin, and the tube is typically sent to the toxicology lab section. Option B is incorrect as blood typing is usually conducted using a SST (Serum Separator Tube) and would be sent to the blood bank. Option C is incorrect because Glucose GTT (Glucose Tolerance Test) is typically run with a Grey top tube containing sodium fluoride and potassium oxalate, and it would be sent to the chemistry lab. Option D is incorrect as PK (Pyruvate Kinase) test is usually done using a Lavender top tube with K2EDTA as the anticoagulant, and it would be sent to the chemistry lab. Therefore, the answer choice A is the correct option for the test, anticoagulant, and lab section associated with a ROYAL BLUE tube.
