Seven Reasons to Get a Blood Test Done at Regular Intervals

Your body requires maintenance and care; much like your house and car. Blood tests help detect diseases, determine your blood group, or check if yours is a universal blood type. Here are seven  reasons to seriously consider getting a blood test done at regular intervals. But before that, let’s clear some basics about blood and blood tests in general. 

A brief overview on blood and its composition: 

Blood is a fluid connective tissue containing plasma that runs throughout the human body. It has sub-parts such as erythrocytes (RBCs), Leucocytes (WBCs), and blood platelets. These parts are cognizable only under a microscope, and they make up about 40% of the blood’s volume. RBC is responsible for the color of the blood (it contains hemoglobin), while WBC performs diapedesis to ward off antigens. Humans have different blood groups. O+ is a universal blood type, and AB is the universal recipient.

Seven key reasons for getting blood tests done

  • It can detect organ-related ailments like kidney anomalies, liver function, etc.

Early detection is the key and the best preventive tool for any anomaly. The same goes for organ-related ailments. All such diseases or disorders can be easily detected through a blood test. For instance, your potassium count can tell how your kidneys are doing. Tests like LFT (Liver function test) are vital for assessing the condition of a patient. Thus, it is advised that you get your blood test done regularly instead of waiting for the symptoms to surface.


  • It can detect your deficiencies and check your nutrition levels.

Sometimes your body can be iron deficient, or you may have a Vitamin-D deficiency. If such cases go undiagnosed, they deteriorate and adversely affect the body. Blood tests are an easy way to detect such conditions, which may cause neurological disorders, muscle impairments, metabolic disorders, etc. While a deficiency may sound less problematic, it can have a disastrous effect on your health if ignored. Getting yourself tested regularly can keep things in check and make sure that you tick all the boxes to stay fit. 


  • It can detect diabetes: The key is diagnosis.

How does your doctor know if you have diabetes? Or, more importantly, how does he know which type of diabetes you have? A blood test is the only way to check your fasting and post-fasting glucose levels. Research says that globally, 45.8% or 174.8 million adult diabetes cases remain undiagnosed. Diabetes is detectable and treatable. Please do not become complacent and get yourself tested.  


  • Reasons for shortness of breath and Fatigue: COVID-like symptoms of different diseases.

The pandemic may have created an illusion that shortness of breath and fatigue are symptoms unique to COVID alone. But facts state otherwise. Fatigue is common among people with anemia or a higher risk of heart diseases. A blood test, namely a Full Blood Count or FBC, can diagnose such ailments. 


  • It can help you know the reasons for sudden weight fluctuations and other metabolic changes.

Unexplained weight changes can be a matter of concern. This is common for patients with hyperthyroidism and hypothyroidism. Your doctor may ask you for complete thyroid profiling to diagnose your condition better. This procedure, once again, involves a blood test. A blood test can be used to conclude whether your TSH and T4 levels are under control. 

  • Not everything is visible through a physical test.

While nobody doubts the perspicacity of your family doctor, a physical examination isn’t as fool-proof as a blood test. A physical examination delves into the symptomatic treatment of disease and does not go beyond that usually. However, with a blood test, your doctor gets a clearer picture of what’s wrong with your body. A blood test can also detect thrombosis-linked or clotting-related disorders and prevent bigger threats such as embolism.   

  • Detect heart-related ailments before they happen.

A blood test can give you early warnings of an impending heart-related disease. This is necessary, especially when it is about the heart. Early detection can be a godsend. High levels of bad cholesterol, or other harmful substances, can be detected easily through a blood test. Lipid profiling of your blood can tell you about the levels of fat in your blood.

Bottom line: know that each body is different.

The only similarity between humans is that we are all different. A body reacts differently to different diseases, and the reaction varies across people. A blood test is the first step towards a correct diagnosis. Two people differ in immunity, blood group (one can be a universal blood type), or even health conditions. A blood test helps in treating the specific.
