What is Complete Blood Count Test

complete blood count(CBC) is a blood test that is used to evaluate your overall health and also detect a wide range of disorders, such as: anemia, infection and leukemia.

complete blood count test

complete blood count test measures several features of the blood, including:

  • Red blood cells. (They carry oxygen).
  • White blood cells. (They fight infection).
  • Hemoglobin. (The oxygen-carrying protein in red blood cells).
  • Hematocrit, the proportion of red blood cells to the fluid component, or plasma, in your blood
  • Platelets. (They help with blood clotting).

A complete blood count test can:

  • Detect anemia, infection or leukemia,
  • See if you have another health issue,
  • To explain symptoms such as: fever,weakness, bruising, or feeling tired,
  • Keep an eye on a blood condition that you might already have,
  • See how treatments like chemotherapy are affecting your blood.

CBC is very important for several good reasons, including the following:

  • White blood cell count (WBC or leukocyte count).
  • WBC differential count.
  • Red blood cell count (RBC or erythrocyte count).
  • Hematocrit (Hct).
  • Hemoglobin (Hbg).
  • Mean corpuscular volume (MCV).
  • Mean corpuscular hemoglobin (MCH).
  • Mean corpuscular hemoglobin concentration (MCHC).
  • Red cell distribution width (RDW).
  • Platelet count.
  • Mean Platelet Volume (MPV).

Preparations for CBC

Before you undergo a CBC test you must prepare. We suggest you to:

  • Make sure you wear a short-sleeved shirt or a shirt with sleeves that you can easily rollup.
  • Eat and drink normally before a CBC.
  • However, it depends on your condition as well, so before you take the test you will be in contact with the doctors and they will tell you how to prepare more specifically.
Cholesterol increases the risk of Heart Attack

How Cholesterol increases the risk of Heart Attack


Cholesterol increases the risk of Heart Attack

Are you diligent about getting your cholesterol checked? Many of us aren’t, and it’s because we think we don’t have to. 

First, we must understand what Cholesterol is because we tend to confuse it with fats.

The Liver manufactures cholesterol and sends it out to other parts of the body for the production of hormones and cell membranes.
When doctors measure cholesterol levels, they first look at total cholesterol as a quick way to assess a person’s risk. For a more exact guide, they divide the total level by the HDL level.

Heart Attack risk is minimized by having a lower total cholesterol and a higher proportion of HDL cholesterol. The ratio of total cholesterol to HDL should be less than 4 to 1.

When there is too much cholesterol in your blood, it builds up in the walls of your arteries, causing a process called Atherosclerosis, a form of heart disease. The arteries become narrowed and blood flow to the heart muscle is slowed down or blocked. The blood carries oxygen to the heart, and if not enough blood and oxygen reach your heart, you may suffer Chest pain. If the blood supply to a portion of the heart is completely cut off by a blockage, the result is a Heart Attack.

Cholesterol is not the same as fat. You might be surprised to learn that your body actually needs cholesterol to function normally and to stay healthy. But what we need to remember is that our bodies are fully capable of making all the cholesterol it needs. It’s what you put into your body (yes, we mean those salty snacks and baked goods), and in some cases your family health history that causes trouble.

Deep Vein Thrombosis


Deep Vein Thrombosis

Deep Vein Thrombosis (DVT) is a blood clot that forms in a vein deep in the body. Most deep vein clots occur in the lower leg or thigh.  The blood clots of deep vein thrombosis can be caused by anything that prevents your blood from circulating or clotting normally, such as injury to a vein, surgery, certain medications and limited movement.

Here are a few cases that increase your chances of DVT

  • If you are over 40 years old
  • Limited move. (If you don’t move for a long period of time, blood starts to pool in your lower legs)
  • Obesity. (The higher your Body Mass Index, the higher the risk for DVT)
  • Other health issues. (If you have been diagnosed with a heart disease, lung disease or cancer, you are more likely to get DVT)
  • During pregnancy or after giving birth. (When a woman is expecting a baby, the levels of estrogen rise. This may cause the blood to clot more easily)
  • Birth control pills or other hormone pills. (If you take any of these pills during your pregnancy, you are more likely to get DVT because many of these pills contain high levels of estrogen).
  • Symptoms of DVT may include:
  • Swelling in one or both legs
  • Pain or tenderness in one or both legs, even if it’s just when you stand or walk
  • Warm skin on your leg
  • Red or discolored skin on your leg
  • Veins you can see
  • Tired legs etc.

There are a few ways to treat Deep Vein Thrombosis. Here are a few examples listed:

  • Anticoagulants. (Anticoagulants are types of drugs that inhibit thrombus formation by manipulating the blood coagulation process. There are a few types of anticoagulants, but the doctor will tell you which is the right one for you based on the indication of any other medical conditions.
  • Compression stockings. (The compression helps move excess fluid back into the capillaries and helps prevent too much fluid from leaking out of the capillaries)
  • IVC or Inferior Vena Cava. (This procedure involves inserting a filter into the vein, this way preventing the large fragments that may break loose from clots, from lodging into the lungs)
  • Surgical thrombectomy. (This is a type of surgery that removes a blood clot from a vein or artery by making an incision into the blocked blood vessel.
  • The most common tests for diagnosing deep vein blood clots is Ultrasound and Dimer test. Ultrasound test uses sound waves in order to create pictures of blood flowing through the veins in the affected leg. While the Dimer test measures a substance in the blood that’s released when a blood clot dissolves.

HBA1C Test

HbA1C Test

HbA1c refers to glycated haemoglobin (A1c), which identifies average plasma glucose concentration.
The amount of glucose that combines with this protein is directly proportional to the total amount of sugar that is in your system at that time.
The #HbA1c test is also known as the glycated haemoglobin test. This is a blood test and it is very important because it gives a good indication of how well your diabetes is being controlled.
The blood test for HbA1c level is performed in people with type 1 and type 2 diabetes mellitus.

Type 1 Diabetes – A chronic condition in which the pancreas produces little or no insulin.

Type 2 Diabetes – A condition which develops if your body can no longer respond effectively enough to its own insulin to prevent your blood glucose levels from going too high

Ranges of the Test

The range values of the test, lets you know the diabetic condition of a person.
Normal Range
4% and 5.6%
Pre-Diabetic Range
5.7% to 6.4%
Diabetic Range
6.5% or Higher
