Red Blood Cell Count (RBCs)

Red platelets convey oxygen to the body.

Ordinary Values:

Men: 4.7 to 6.1 million cells for every microliter.

Ladies: 4.2 to 5.4 million cells for every microliter

Low outcomes can demonstrate blood misfortune, issues with the bone marrow, leukemia, and unhealthiness. High outcomes can show heart issues, kidney illness, over bonding and dehydration.

White Blood Cell Count (WBCs)

These cells are the contamination battling part of the blood and assume a part in irritation.

Typical Values: 4,500 to 10,000 cells/mcl

A low count can demonstrate bone marrow issues or different issues keeping the body from making enough of these platelets, substance openness, immune system sickness, and issues with the liver or spleen. Undeniable levels can demonstrate the presence of tissue harm (consumes), leukemia and irresistible infections, or the utilization of specific meds, for example, steroids.

This is the level of the blood that is made out of red platelets.

Ordinary Values:

Men: 40.7% to 50.3%

Ladies: 36.1% to 44.3%

Low hematocrit levels can demonstrate frailty, blood misfortune, bone marrow issues, ailing health and then some. Significant levels can demonstrate parchedness, polycythemia vera, smoking, living at a high elevation and heart infections that are available at birth.


Hemoglobin is a protein on red platelets that conveys oxygen. Too not many red platelets is called sickliness.

Ordinary Values:

Men: 13.8 to 17.2 grams/deciliter

Ladies: 12.1 to 15.1 grams/deciliter.

Low levels might show blood misfortune, brought about by injury, medical procedure, injury or potentially a long haul however limited quantity of draining in the body, like a ulcer in the stomach. It can likewise show a powerlessness to make sufficient blood, which is much of the time brought about by a lack in iron, B12 or folate.

Platelet Count (Thrombocytes)

  • Platelets are the piece of the blood that makes the blood coagulation.
  • Ordinary Values: 150,000 to 400,000 for every mm3.
  • Low levels might show the individual is getting chemotherapy, hemolytic iron deficiency, the presence of a substitution heart valve, leukemia or a new blood bonding. Significant levels can be brought about by weakness, explicit sorts of malignant growth, polycythemia vera, a new medical procedure to eliminate the spleen and other wellbeing issues.

WBC (White blood count)

If this result is low, it may show a problem such as a bone marrow disorder and decreased ability to fight infection. If elevated, it could indicate a response to an infection. If greatly increased, could indicate a blood cancer such as leukemia.

Red Blood Cells

These measurements show different characteristics of your body’s red blood cells. They can indicate that you have a low blood count (anemia) and if anemic—what dietary deficiency may be contributing to your anemia. They also give information to your provider about hereditary disorders that affect blood cells, such as thalassemia, a condition that causes your body to have less hemoglobin than normal.

  • RBC (Red blood count) 
  • HGB (hemoglobin) 
  • HCT (hematocrit)
  • MCV (mean corpuscular volume)
  • MCH (mean corpuscular hemoglobin)
  • MCHC (mean corpuscular hemoglobin concentration)

Platelet Count (PLC)

Platelets, are the smallest type of blood cell and one of the main components in your body’s ability to clot, which stops bleeding when you are injured. If there are too few platelets, uncontrolled bleeding may be a problem. If there are too many platelets, there is a chance of a blood clot forming in a blood vessel. Platelets may also be involved in hardening of the arteries (atherosclerosis).

Differential (DIFF)

This component of the CBC/DIFF breaks down the different forms of white blood cells that make up your immune response to infections. The main cells present, in order of frequency, are neutrophils (fight bacterial infections), lymphocytes (seen more in viral and long-term immune responses), monocytes (fight both bacterial, viral and fungal infections) and eosinophils (increased in allergic reactions).
