What lab values are in a CBC?
A CBC test usually includes:White blood cell (WBC, leukocyte) count.
White blood cell types (WBC differential).
Red blood cell (RBC) count.
Hematocrit (HCT, packed cell volume, PCV).
Red blood cell indices.
Platelet (thrombocyte) count.
Mean platelet volume (MPV)..
Is fasting required for a CBC blood test?
When your doctor orders a CBC, there are no special preparations you’ll need to take before the test. You are not required to fast (not eat solid foods for 12 hours or so), unless you are having other tests done at the same time that require it.
Does a CBC test for kidney function?
Creatinine clearance—this test measures creatinine levels in both a sample of blood and a sample of urine from a 24-hour urine collection. Decreased creatinine clearance may indicate decreased kidney function. Hemoglobin (part of a complete blood count or CBC)—may be done to detect anemia.
How can you tell the difference between a viral and bacterial infection on a CBC?
For example, if you have a bacterial infection, you will have an increase of neutrophils and a decrease in lymphocytes. Conversely, if you have a viral infection, you will have a decrease in neutrophils and an increase in lymphocytes.
Can you brush your teeth when your fasting for a blood test?
Fasting means that, with the exception of water, you refrain from eating or drinking for a minimum of 8 hours (10 to 12 hours is preferable) prior to the test. This means no coffee or tea beforehand, but taking your vitamins or medications is okay. Brushing your teeth or using mouthwash won’t influence the test.
What happens if I fast longer than 12 hours before blood test?
MEDICAL ADVICE. Many other fasting patients attend early, so you may experience some delays. Unfortunately it’s not possible to make appointments. IF YOU FAST LONGER THAN 16 HOURS – YOUR RESULTS MAY NOT BE ACCURATE, OR WE MAY NOT BE ABLE TO PERFORM SOME OF THE TESTS.
Is WBC count elevated in viral infection?
Neutrophils, which account for about 70% of white blood cells, can increase in response to bacterial infections as well as to physical or emotional stress. A high lymphocyte count may occur when there is a viral or bacterial infection. Increased monocytes can indicate chronic inflammation.
Do lymphocytes increase with viral infection?
Lymphocytes are a type of white blood cell that play several roles in the immune system, including protection against bacteria, viruses, fungi, and parasites. All three types can be increased in response to infections or cancer. However, in some cases only a specific type of lymphocyte is increased.
Can CBC detect viral infection?
A CBC test usually includes: White blood cell (WBC, leukocyte) count. White blood cells protect the body against infection. If an infection develops, white blood cells attack and destroy the bacteria, virus, or other organism causing it.
Is 10 hours long enough to fast for blood work?
It is important that a person has not had anything to eat or drink other than water for 8 to 10 hours before a fasting blood glucose test. Fasting helps ensure that the blood test records an accurate measure of fasting blood sugar levels. The results help a doctor to diagnose or rule out diabetes.
Does CBC show liver and kidney function?

The antibodies attach to a cell infected by the virus and cause the virus to be destroyed. This test looks for antibodies to a specific viral infection. It is generally done on a blood sample.
