Blood Chemistry Profile and Hemogram

Here is information about other blood tests you might have at your screening.

blood chemistry profile is a screening that measures:

  • Blood glucose levels (most significant; see section on blood glucose). 
  • Blood urea nitrogen (BUN) and creatinine analysis, which assesses four components that work together to help keep the kidneys healthy.
  • Electrolyte levels in bloodstream (sodium, potassium, chloride and bicarbonate). These elements promote health of cell membranes and carry electrical energy for functions including muscle contractions and communication between cells.

hemogram screening, or complete blood count, screens for a range of conditions including anemia and infection. It is made up of four tests that evaluate:

  • White blood cells (WBC). These are the body's primary means of defense against illness. White blood cells react to invasive bacteria by attacking them and preventing potential infection.
  • Red blood cells (RBC). They transport oxygen from the lungs to the organs, muscles and other body tissues.
  • Hemoglobin (HGB). This test measures the blood protein that helps to transport oxygen to the body tissues and organs.
  • Hematocrit (HCT). Also related to red blood cells, this test measures the total volume of red blood cells in the bloodstream.

A significantly low reading on any of these tests could signal the presence of disease. Your doctor can advise you on next steps, if needed.
