Most Common Type Of Blood Tests To Diagnose Diabetes

If you have symptoms such as increased thirst, frequent urination urge, unexplained weight loss, increased appetite, and a tingling sensation in your hands or feet, you may be diabetic. But, diabetes tests will help you  diagnose diabetes more accurately. 

Symptoms of diabetes appear suddenly, so testing glucose levels regularly is necessary. Since  the symptoms of diabetes and prediabetes occur gradually, the side effects may be unclear.

Common Blood Tests To Diagnose Diabetes

HbA1C Test

This blood test measures your average glucose level over a period of months. The HbA1C test determines the rate at which glucose is linked to haemoglobin, a protein that transports oxygen in red blood cells. The higher the glucose levels, the more haemoglobin with sugar attached. Diabetes is diagnosed when your A1C result is 6.5 percent or above on two tests which are different. Prediabetes is indicated by A1C readings between 5.7 and 6.4 percent. Under 5.7, everything is considered normal.

Fasting Blood Sugar Test

In this test, blood samples will be collected after you have observed an overnight fast. Normal fasting blood sugar levels are fewer than 100 mg/dL (5.6 mmol/L). Fasting blood sugar readings of 100 to 125 mg/dL (5.6 to 6.9 mmol/L) are considered prediabetic. Diabetes is diagnosed when two independent blood sugar tests reveal a result of 126 mg/dL (7 mmol/L) or greater.

Complete Blood Test

A Complete Blood Count (CBC) is a blood test that is used to assess an individual's overall health and detect a variety of illnesses ranging from anaemia to leukaemia.

The CBC test measures several components and features of one's blood, including oxygen-carrying red blood cells, white blood cells, haemoglobin, the protein in red blood cells that carries oxygen, hematocrit, the amount of plasma in a person's blood, as well as platelets, which aid in blood coagulation.

Postprandial Glucose Test (PPBS)

This is a blood glucose test that determines the level of a specific type of sugar called glucose. Glucose levels in the blood are measured in this test, particularly after a meal.

Normally, blood glucose levels rise somewhat after a meal. This enlargement induces the pancreas to release insulin, which aids the body in eliminating glucose from the blood and storing it for use as energy. Diabetes patients may not respond appropriately to insulin, resulting in elevated blood glucose levels. High blood glucose levels can harm the eyes, kidneys, nerves, and veins severely.

Cholesterol Test

Because diabetes significantly raises a person's risk of heart disease, it is unavoidable for them to have a blood test to check their cholesterol levels more frequently, if their cholesterol levels are high, they are more prone to diabetes.

Creatinine Blood Test

A creatinine blood test determines the amount of creatinine present in the blood. Creatinine is a waste product formed when creatine separates. Creatine can be present in muscle. Creatinine levels in the blood might inform your doctor about how well your kidneys are working.

Electrolytes

This is a blood test that measures the main electrolytes in the body, which include sodium, potassium, chloride, and bicarbonate (CO2) — it can be used to evaluate heart disease symptoms and track the effectiveness of treatments for high blood pressure, heart failure, and liver and kidney disease.
