Insulin (R)

Insulin is a hormone that originated in the beta cells of the Pancreas. It’s a very important hormone in transporting and storing Glucose. It’s also an energy source for the body. This test evaluates the Insulin Level in the blood randomly. It is used to diagnose hypoglycemia (Low Blood Glucose) and Insulin-producing Tumors.

Insulin R

Why Insulin (R) Test?

CLINICAL INFORMATION

Diabetes mellitus refers to a term for several conditions with metabolic disorders characterized by high blood sugar levels over a prolonged period of time. This disorder is either due to insufficient insulin produced by the pancreas and/or absence of insulin (due to autoimmune disease i.e destruction of beta cells), and/or the body not responding to insulin (insulin resistance). Clinical manifestations or symptoms include hyperglycemia, polyphagia (increased appetite), polydipsia (increased thirst), polyuria (frequent urination), blurred vision, headache, fatigue, slow wound healing, diabetic dermadromes etc. A metabolic syndrome is a group of disorders that interlink together (high blood sugar, high BP, excess body fat around the waist, low HDL, high TGs etc) and increase one’s risk of type-2 Diabetes mellitus and heart diseases. Types include Type-1 Diabetes mellitus, Type-2 Diabetes mellitus, Juvenile Diabetes mellitus, Gestational Diabetes mellitus etc. Diabetes mellitus if left untreated can result in end-organ damage such as diabetic retinopathy (affecting the eye), diabetic neuropathy (affecting the nerves), and diabetic nephropathy (affecting the kidneys). Complications include obesity, diabetic ketoacidosis (Kussmaul breathing), insulin resistance, macro-vascular diseases (like stroke and peripheral artery diseases), glaucoma, cataracts, heart diseases, chronic kidney disease, foot ulcers, cognitive impairment, Alzheimer’s disease (insulin resistance accelerates the deposition of beta-amyloid in the brain), pseudo motor dysfunction, muscle atrophy, seizure, unconsciousness, hyperosmolar hyperglycemia (that can lead to coma and death) etc. Insulin is the principal hormone that regulates the uptake of glucose from the blood into most cells of the body (eg. liver, adipose, muscles etc). Insulin is released from the beta cells of the pancreas in response to an increase in the glucose levels in the bloodstream after a meal. Insulin helps to store glucose in the liver as glycogen, muscles and fats (excess glucose is converted to fat and is stored in the adipose tissues), and thus regulates the body’s metabolism of carbohydrates, fats and proteins. Therefore abnormal levels of insulin can cause serious consequences. Lack of insulin fails to store glucose in muscles and/or liver and lipogenesis cannot be triggered, instead it favours lipolysis and hence fats break down to form keto acids (ketone bodies). Thus the accumulation of high ketone bodies can cause imbalance and result in diabetic ketoacidosis (which if untreated can lead to coma and eventually to death). While high levels of insulin in the blood is known as insulinemia. It can cause obesity which in turn leads to heart diseases and furthermore it may also further complicate abnormal pathologies like insulin resistance, Polycystic Ovaries (PCOs), cancers etc. Causes for low insulin levels include type-1 Diabetes mellitus, removal or pancreatic disease, hypopituitarism etc. Causes for high insulin levels include insulin resistance, obesity, tumours of the pancreas (insulinomas), Cushing’s syndrome, acromegaly, certain medications (corticosteroids, Oral Contraceptive Pills - OCPs) etc. High-risk factors involved in causes of insulin resistance are hereditary factors (genetics), stress, sleep, high carbohydrate diet, obesity (high BMI) etc. The insulin resistance test (also known as 4 hours kraft insulin survey) is the gold standard test performed to test for insulin resistance. An Insulin resistance test is generally performed to assess the increased incidence of developing diabetes mellitus. This test is also useful in screening for insulin production by the beta cells of the pancreas, hence helping as a biomarker for diagnosing pre-diabetes, detecting diabetes mellitus (type-2 diabetes), increased cardiovascular risk. Furthermore, this test helps to screen detect hypoglycemia (with clinical manifestations of dizziness, sweating, hunger, blurred vision), insuliomasetc moreover it aids in the study of insulin resistance (Type-2 diabetes) and helps in the prognosis. Additional tests include HbA1C, C-Peptide, fructosamine, glucagon test etc. Other associated tests include CBC, tests for anaemia, Glucose Tolerance Test - GTT, ELISA for autoimmune disease, imaging studies etc.
