What are the 3 most common blood tests?

Blood tests are performed because they reveal the intricate workings of the body, which is why they are essential to one’s health. When it comes to diagnosing, monitoring, and planning medical treatments, the results of these tests can assist medical professionals. At Dr. Vayas’s Lab, we know the significance of these diagnostic tools for developing individualized treatment plans. As a result, we place a high priority on patient education and care. 

The importance of the three blood tests that are performed the most frequently for overall health is discussed in this article.

1. Complete Blood Count (CBC)

The CBC or Complete Blood Count is the standard blood test that summarizes the different parts of blood. Hemoglobin, platelets, WBCs, RBCs, and hematocrit are all measured during tests. Humans require oxygen, immunity, and clotting.

Red Blood Cells (RBCs)

Red blood cells carry oxygen and carbon dioxide to the lungs and other parts of the body.  Red blood cell counts that are abnormal could mean you have polycythemia or anemia.

White Blood Cells (WBCs)

When the body gets an infection, WBCs are the first thing that protects it.  If your WBC count is high or low, it could mean you have an infection, inflammation, or a problem with your immune system.

The hematocrit and hemoglobin

Together with hemoglobin, red blood cells carry oxygen. It measures the size of red blood cells. Any strange changes could mean you have heart or lung issues, anemia, or are dehydrated.


It is impossible to clot blood without platelets. Your health could be negatively affected if you have a low platelet count because you may bleed or clot excessively.

2. Lipid Panel

When it comes to ensuring that your heart remains in good health, careful monitoring of your lipid levels is of the utmost importance. This device is capable of measuring a variety of blood fats, including the following: 

Total Cholesterol

The amount of cholesterol in your blood as a whole is displayed here. When the levels are high, the risk of developing heart disease increases.

LDL cholesterol

Cardiovascular plaque from high “bad” cholesterol, or LDL, increases heart disease and stroke risk.  

HDL cholesterol

In the bloodstream, “good” HDL cholesterol removes “bad” cholesterol. Higher HDL levels lower the risk of developing heart disease.


Particular kinds of fats are found in the blood. High cholesterol, particularly low HDL or high LDL, raises the risk of developing heart disease.

At the Dr. Vayas Lab, we strongly emphasize the importance of a lipid panel in the context of preventive healthcare strategies to identify cardiovascular risk factors at an earlier stage and take preventative measures.

3. Blood Glucose Test

Diagnosis and treatment of diabetes require blood glucose testing. Dr. Vayas Lab emphasizes this test because it helps us diagnose and manage diabetes over time. Diabetic prevention can be achieved with basic blood glucose monitoring.

Fasting Blood Sugar (FBS)

FBS tests are simple but effective diabetes diagnostics. Doctors can assess glucose management by checking blood sugar after eight hours without eating. Average fasting blood sugar is 70–99 mg/dL. At 126 mg/dL or higher, two tests detect diabetes; 100–125 is prediabetes.

Early FBS detection of diabetes and prediabetes allows prompt treatment. Exercise and ketosis delay diabetes.

Hemoglobin A1c (HbA1c)

We measure HbA1c and average blood glucose every two to three months for long-term control. The assay measures glucose on oxygen-transporting red blood cell hemoglobin. Two tests show 5.7% A1c is normal, 5.7% to 6.4% in prediabetes, and 6.5% or higher in diabetes. 

Diabetes patients adjust treatment and control with HbA1c. Many patients prefer the A1c test over the FBS test because it does not require fasting.


The significance of blood tests in diagnosing, monitoring, and effectively treating medical conditions is something that Dr. Vayas Lab is well aware of. CBC, Lipid Panel, and Blood Glucose Tests are carried out to provide essential information regarding the patient’s health. Using these tests, we can provide patients with individualized care supported by evidence. Utilizing the most cutting-edge medical technology and research, we can provide unparalleled treatment. Dr. Vayas Lab utilizes the most common and reliable blood tests to perform routine checkups and diagnose chronic conditions.
