Blood testing is crucial for assessing our health and diagnosing various medical conditions. Private blood tests offer a convenient and comprehensive way to gain insight into our well-being.

This article will explore the five main blood tests commonly performed, their significance in health assessment, and the benefits of opting for private blood testing.


Complete Blood Count (CBC) 

Complete Blood Count, or commonly referred to as CBC, is one of the most common blood tests. It provides valuable information about various components of the blood: especially the red blood cells (RBCs), white blood cells (WBCs), and platelets. Any abnormality in their numbers is a matter of concern.

RBCs carry oxygen throughout the body, and their levels are crucial in determining oxygen-carrying capacity.

WBCs are key players in the body’s immune response, defending against infections and foreign substances.

An abnormal WBC count may suggest an infection, inflammation, or an underlying immune disorder. Platelets come into the picture when it comes to blood clotting and preventing excessive bleeding. Hemoglobin is a protein within RBCs responsible for carrying oxygen throughout our body.

Moreover, the test also gives the values of hemoglobin and hematocrit levels. Hemoglobin is a protein within RBCs responsible for carrying oxygen throughout our body.

Hematocrit, on the other hand, represents the percentage of blood volume occupied by RBCs. These parameters together reflect the oxygen-carrying capacity of the blood.

Abnormal levels of hemoglobin or hematocrit can indicate various conditions. These include anemia, dehydration, or other conditions affecting blood volume or oxygen transport.

CBC helps diagnose and monitor conditions like anemia, infections, and blood disorders. By identifying abnormalities, a CBC aids healthcare professionals in determining appropriate treatments.


Lipid Profile Test 

The Lipid Profile Test helps measure cholesterol and triglyceride levels in the blood. Elevated levels of cholesterol and triglycerides can cause severe heart problems. This blood test provides valuable information about an individual’s cardiovascular health.

Understanding lipid levels can help make dietary and lifestyle changes to reduce the risk of heart-related issues. Private blood testing allows individuals to monitor their lipid levels regularly and take proactive measures to maintain a healthy heart.


Blood Glucose Test 

This test calculates the amount of glucose (sugar) in the blood. Patients with diabetes should consult their doctor regularly for a blood glucose test. This helps with regular monitoring if the values are abnormally low or vice versa.

Higher than normal values [fasting blood glucose- between 70 and 100 mg/dL (3.9 and 5.6 mmol/L)] of the test indicate diabetic conditions. At the same time, a decreased blood glucose value is called hypoglycemia. Both abnormalities are a matter of concern and should be addressed by a doctor.

Private blood tests allow individuals to monitor their blood glucose levels and ensure optimal diabetes management.


Liver Function Test 

The Liver Function Test evaluates the liver’s health by measuring various enzymes, proteins, and other substances produced by this vital organ. Liver diseases can be diagnosed and treated early with the help of this test.

By monitoring liver function, individuals can identify abnormalities and take the necessary steps to protect and improve liver health. Private blood tests provide an opportunity to assess liver function regularly, allowing for early detection and intervention.

A Liver Function Test measures two important markers (ALT and AST). These are the two enzymes found in liver cells. High levels of these enzymes indicate liver damage or inflammation. Another crucial marker is bilirubin, a yellow pigment formed at the breakdown of red blood cells.


Thyroid Function Test

Blood TSH (thyroid stimulating hormone), T3, and T4 are measured in a thyroid function test. These hormones regulate metabolism, energy levels, and basal metabolic rate.

An increased level of these hormones above the normal level is called hyperthyroidism, causing anxiety, fatigue, frequent bowel movements, etc.

A lower value of these hormones is called hypothyroidism and causes fatigue, weight gain, and joint and muscle pain. Both of these conditions are dangerous to the body. Regular monitoring through blood tests helps individuals manage thyroid disorders effectively.


In a Nutshell 

Health testing is essential for assessing our health, and identifying potential medical conditions can only be done through blood testing.

The five main blood tests mentioned above (CBC, lipid profile, blood glucose, liver function test, and thyroid function test) should be done by every individual at regular intervals. This helps diagnose any abnormality in its early stages, and treatment can be carried out accordingly.

Taking blood tests enables individuals to take control of their health and make informed decisions regarding their overall well-being. For those residing in London and seeking private blood tests and health testing services, please feel free to schedule an appointment with our personnel.
