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.
