An Insulin test measures the level of insulin in the bloodstream. Insulin is a hormone produced by the pancreas that allows glucose to enter the cells in your muscles, fat, and liver, where it is used for energy. If the pancreas does not produce the correct amount of insulin at the right time, it can lead to conditions such as hypoglycaemia (low blood sugar) and hyperglycaemia (high blood sugar). Therefore, an Insulin test is important for determining if your insulin levels are within the normal range.

Insulin Blood tests also help doctors diagnose causes of hypoglycaemia, assess insulin resistance, and determine if insulin therapy is needed for patients with type 2 diabetes. They also monitor the effectiveness of pancreatic islet cell transplantation in type 1 diabetes, an autoimmune condition that destroys the insulin-producing islet cells in the pancreas.

If you live and have symptoms of a health condition related to insulin, an Insulin Blood test can determine how much insulin your pancreas is producing. Book an Insulin Fasting test today to check your insulin levels.

For accurate results, consider the following when scheduling a Fasting Insulin test at home :

• Prerequisites

It is required to fast (refrain from eating or drinking) for 10 to 12 hours prior to the Insulin test.

• Best Time to Get Tested

The Fasting Insulin test can be scheduled at any time of the day following a 10- to 12-hour fasting period.

• Who Should Take an Insulin Fasting Test

While anyone can schedule an Insulin Fasting test, it is commonly ordered for the following people:

• Cautions Before Taking an Insulin Fasting Test

There are generally no specific precautions for the Fasting Insulin test. However, if you take biotin supplements (vitamin B7) or medications containing biotin, your doctor may advise you to discontinue them at least one day before your test. Always consult your doctor before stopping any medications.

Your doctor may suggest an Insulin Blood test to identify the underlying cause if a recent blood glucose test showed low blood sugar levels. Symptoms of low blood sugar include:

• Dizziness

• Anxiety

• Trembling

• Sweating

• Hunger

• Confusion

• Nausea

• Irritability

• Weakness

• Headache

• An irregular heartbeat

This test may also be ordered by your doctor to diagnose and monitor insulin resistance, which is more likely if you have prediabetes, type 2 diabetes, PCOS, or heart disease. Insulin Blood test also helps guide treatment decisions for type 2 diabetes, determining if insulin therapy is necessary. Other reasons for needing this test include:

• Islet cell transplantation, in which insulin-producing pancreatic tissue is transplanted, necessitates insulin testing to assess transplant effectiveness.

• Removal of insulinoma, a non-cancerous pancreatic tumour causing excessive insulin production and low blood glucose. Post-surgery, insulin testing may be required to verify the absence of tumour tissue and monitor for recurrence.
