What is CBC or Complete Blood Count?
The complete blood count (CBC) is a blood test used to check for a variety of disorders, such as anaemia, infections, and leukaemia, as well as to screen for your general health. The test procedure, your age, gender, health history, and other factors may affect the test findings. Your test findings might not indicate a problem with you. Find out what your test findings signify for you by asking your healthcare provider. Numerous factors can produce abnormal test findings. Some of these causes might not require medical attention.
The amounts of various parameters in a complete blood count test can reveal information about a variety of potential issues, including: The test pulls a lot of data from the blood sample you provided, such as:

RBC is the most prevalent kind of blood cell; they are sometimes referred to as erythrocytes.form of a biconcave discCount: Males 5.2–5.8 million per millimetre, and females 4.3–5.2 million. RBC count measures how many red blood cells there are. RBCs eliminate extra carbon dioxide from the body while delivering oxygen throughout it. A low RBC count could indicate anaemia or other illnesses. Rarely, blood flow issues may result from an excess of RBCs.
Hgb and Hb, or haemoglobin
Red blood cells contain the protein haemoglobin. It transports oxygen from the lungs to the body’s other tissues. Anaemia to lung illness are just a few of the issues that abnormalities can indicate. Mild anaemia is the most frequent condition that the CBC identifies. Depending on how severe the anaemia is and whether other issues are discovered during the exam, you can have additional testing.
A protein called haemoglobin aids in transferring oxygen from your lungs to the rest of your body. Your heart and lungs may have to work harder to keep your body supplied with adequate oxygen to operate correctly if your haemoglobin levels are low. High haemoglobin levels may be present in polycythemia patients.Low haemoglobin levels may be present in anaemic patients.
HCT, or hemocrit or Packed cell volume
This refers to how many red blood cells are present in a given volume of whole blood. A low hematocrit could indicate excessive bleeding. You might also have an iron shortage or another condition, according to this. Dehydration or other illnesses may be to blame for an elevated hematocrit.
MCV or Mean Corpuscular Value
MCV measures the size of your red blood cells on average. When your red blood cells are larger than usual, MCV increases. This occurs if you have anaemia brought on by insufficient levels of folate or vitamin B12. Smaller red blood cells may indicate further anaemias, such as iron deficiency anaemia.
MCH or Mean Corpuscular Hemoglobin
The amount of haemoglobin in red blood cells can be determined using a mean corpuscular haemoglobin (MCH) blood test. It is one of the frequent tests that many individuals have at some point in their lives called a complete blood count (CBC). Low MCH levels may indicate autoimmune illness, anaemia, or other problems. A high MCH level could indicate a thyroid problem or lung disease. Heavy alcohol usage and the use of specific drugs can both cause MCH levels to rise.
MCHC or Mean Corpuscular Hemoglobin Concentration
The amount of haemoglobin in your blood is gauged by the abbreviation MCHC, or mean corpuscular haemoglobin concentration. A MCHC test may be performed as part of a comprehensive health examination or it may be employed to assist in the identification of certain health issues.
An MCHC test can help you avoid or treat a range of health issues since abnormally high or low haemoglobin levels in your blood cells might be an indication of existing or upcoming health issues.
RDW or Red cell distribution width
RDW measures how your red blood cells differ in size. (RDW, RDW-CV, or RDW-SD) is the name of this test. For instance, if you have anaemia, your red blood cell size variations would likely be more pronounced.

The quantity of white blood cells (WBCs) in your blood is determined by this test. The term “leukocyte” also refers to white blood cells.
White blood cells are produced by your bone marrow and released into the bloodstream. You can fight infection with the aid of white blood cells. They are a component of the immune system of your body, which keeps you healthy and heals you when you become ill. White blood cells fight out any foreign bacteria, fungi, or viruses that make their way into your body.
Your white blood cell count is higher than usual while you are ill. This is due to the fact that more of these cells are being released by your body to combat the illness. But your white blood cell count might become extremely low if you have certain diseases like HIV or cancer.
Total leukocyte count measures how many white blood cells (WBCs) there are. The many types of WBCs include 5. All contribute to the battle against infection. A bodily infection or inflammation may be present if your WBC count is high. A low WBC count could indicate increased infection risk.
Additionally, differential blood count is used in conjunction with leukocyte count (WBC) to produce absolute values for each type of white blood cell, such as absolute neutrophil count, absolute lymphocyte count, or absolute eosinophil count. These absolute values typically provide more meaningful information than percentages of each, as opposed to relative counts.

A platelet count (PLT). Cell fragments called platelets are involved in the coagulation of blood. A low platelet count could increase your risk of bleeding. Too many could indicate a variety of different conditions. to identify and/or keep track of specific clotting and bleeding issues
MPV or Mean Platelet Volume
In MPVAVERAGE size of platelets is measured. it helps to diagnose bleeding disorders and diseases of the bone marrow. A marker of platelet activation.
PDW or Platelet Distribution Width
PDW are more specifically remarkable in platelet activation as compared to MPV, since unlike MPV it does not increase during simple platelet swelling.
When CBC test is Prescribed?
- This test may be required if you have:
- uncommon bruising or bleeding
- Inflammation or infection
- persistence of weakness and fatigue. These could be anaemia symptoms.
- Additionally, if your medical professional suspects that you may have a certain disease or condition, you might have this test. Alternatively, you might undergo this test as a standard component of a physical examination. The test might also be used to evaluate the efficacy of particular treatments.
How is a test for a complete blood count conducted?
A member of your medical team draws blood for a complete blood count by putting a needle into a vein in your arm, typically near the bend of your elbow. An analysis of the blood sample is done in a lab. You can resume your regular activities right away.
WHAT Preparation is Needed for the CBC Test?
Make sure all of the medications, herbs, vitamins, and supplements you take are disclosed to your healthcare professional. This includes any over-the-counter medications and other illicit substances you may use.
What further tests might I have in addition to this one?
In the event that the findings of your CBC are abnormal, your doctor might recommend additional testing. These could involve checking your urine, bone marrow, or spinal fluid in addition to other blood tests.
