It is known as the CBC (also known as HEMOCYTOMIC EXAM is an extremely vital blood test, which is usually prescribed for a pre-screening of the health condition of a person. it helps to detect alarm signals for which it is essential to conduct a thorough examination.

What do the CBC focus on?

The CBC permits us to keep an inventory of all the blood cells and is usually indicated by abbreviations that aren’t always obvious however, is crucial to understand and comprehend.

Why is it important to carry out this task?


The CBC is a test designed to verify certain blood parameters of the patient. It is prescribed by a doctor for a variety of reasons.

to track the progress of the ongoing treatments in the case of obvious pathologies

to clarify a possible pathology by confirming the diagnosis of inflammation, infection or any other cause;

to control the number of certain cells that are present in blood, whose insufficiency or excess can cause significant pathologies;

to assess and determine one’s health condition.

Who is responsible for the task?

The CBC is an assessment which everyone must perform at least once in a year, in spite of the absence of any symptoms.

It is highly advised and is essential in the event of specific symptoms that may cause infections or anemia and any situation that the physician must be able to rule out any disease that could affect those blood cells.

Patients who are undergoing chemotherapy or other treatments that can seriously weaken the body must take their blood pressure often to maintain blood counts and the potential side effects from drugs under control.

Where is it possible to perform it? Do you need to fast?

For a CBC you simply need to visit the local lab and collect one simple blood sample. it’s not necessary to fast, a condition that is often needed to perform other types of tests like blood glucose.

How do you read the count of blood?

To understand the outcomes from an CBC it is crucial to be able to comprehend the acronyms by which the individual parameters are identified:

Hb (Hemoglobin) Hemoglobin, the protein that contains an iron atom bound to it that is accountable for oxygen transport, and is the pigment in red blood cells. It provides blood the characteristic red hue Low levels of hemoglobin can be a sign of moderate, strong or mild anemia.

HCT (Hematocrit) HCT (Hematocrit): is percent of the red blood cells in the total volume of blood. The HCT is a measure on the volume of blood. In fact, if it is high, or the HCT is high that means that the blood is extremely dense. If it’s low, it means that the blood is less fluid.

The RBC (Red blood cells) is the term used to describe the amount of cells called red blood cells, also known as erythrocytes, that are present in blood. In the absence of these, you can develop anemia, a condition that is known as anemia in excess, it is known as the polyglobulia, or erythrocytosis. When the number of red blood cells in your body are less than the normal size, the possibility of Mediterranean anemia could be suspected;

MCV (mean corpuscular volume) refers to the average size of blood red cells.

MCH (Mean Corpuscular Hemoglobin) is the amount of hemoglobin found in every red blood cell.

“MCHC” (Mean of Corpuscular Hemoglobin Content) is the average hemoglobin content in red blood cells.

RDW (Erythrocyte Distribution Width) is an indicator of the variance in the size of erythrocytes;

They are also known as WBC (White blood cells, also known as leukocytes) These are cells that serve to trigger immune responses and fight off infections. If their numbers are lower than the normal value, is known as leukopenia. when the number of leukocytes is more than normal, then we refer to leukocytosis. By using the abbreviation WBC is typically used to indicate the total quantity of leukocytes. It is followed by the different kinds. Most of the time, in conjunction with this, the CBC is also asked to determine the leukocyte formula. This is the unique count of leukocytes broken down by neutrophils (NEUT) and eosinophils (EO) (BASO), basophils (BASO) Monocytes (MONO) as well as lymphocytes (LYMPH);

PLT (Platelets) The PLT (Platelets) indicates the amount of platelets in blood, per millimeter. They are corpuscular constituents of the bloodthat are that are responsible in preventing blood clotting. The term plateletopeniase is used to describe when and the number is less than normal.

MPV (Mean Platelet Volume) is the standard size of platelets. This lets us distinguish younger platelets, which are smaller than older ones, which are larger;

The PDW (platelet distribution width) is a number which indicates the amount of variance in platelet size If this number lowers, that indicates that the size of platelets is relatively uniform. However, if these values are high, it means that there is a significant variation in the volume of platelets.

PCT (platelet hemotocrit) is a measurement that measures the volume platelets take up in a certain amount of blood.

Not to be lost:

Its results from the CBC consist of an analysis of the blood samples of the patient along with the standard parameters which makes it easy to detect any abnormalities that might be present, but it is vital to mention that the reading of the test must be conducted by the doctor or specialist who asked for them who will evaluate the results and understand how to interpret them in the light of the symptoms or specific circumstances.
