APTT stands for Activated Partial Thromboplastin Time. This determines if the blood can clot. The doctor will draw blood from the body and put it into a blue tube. CBC stands for Complete Blood Count. There are several other subtests conducted with this one. One is the ESR which stands for Erythrocyte Sedimentation Rate.

This test measures the time for the settling of red blood cells in the body. Lytes is really an abbreviation because it is a shortened word that stands for electrolytes. BC stands for Blood culture. Blood cultures are taken to find out what is wrong with the patient. The correct order of draw for these tests is BCS, red with iodine, then APTT and CMP with Lytes, CBC, and then ESR at the end.
