How is a CBC Test Conducted?
At Portea Home Medical Care, the patient will have the option to get his or her blood samples collected at home and the results delivered.

Some blood will be drawn with a syringe from near the crook of the arm. The lab will deliver the results in a day or two.
How is CBC used to measure overall health?
The number of respective blood cells in the body can be indicative of the person’s overall health.
White Blood Cells Count: These cells help to fight infections and a high number of WBC indicates there is some infection in the body. If it is low, then there is a risk of infection as well. The normal range of WBC should be between 4500 to 10,000 cells per microliter.
Red Blood Cells Count: This indicates the number of red blood cells one has and they are very important as they help to distribute blood evenly through the body. A low RBC count could suggest that the patient has anemia. The normal range for RBC in men is 4.5 million to 5.9 million/ mcl while in women it is 4.1 million to 5.1 million cells/ mcl.
HB or Hemoglobin: This is the protein in the blood that holds the oxygen and for men the normal reading should be between 14.17.5 grams per deciliter and for women it is 12.3 to 15.3 gm/ dl.
Apart from the above mentioned aspects, the CBC blood test is also used to reveal vital information about hematocrit, mean corpuscular volume and the number of platelets in the body, which plays a major role in blood clotting. The normal range of platelets in a human body is about 1.5 lakhs to 4.5 lakhs platelets/mcl.
What can be deduced from the results?
When CBC blood tests results are delivered, there are usually two columns- one of which is the reference range while the other column shows the patient’s reading. If the reading of the patient is within the range that is shown in the reference range, then the patient has normal CBC. In case it is lower or higher, then the doctor will take the next course of action.
