Fasting Insulin Test: The Test You Need Right Now

​A fasting insulin test may be your key to an early diagnosis of one of the most common life-threatening disease of today—diabetes.

Diabetes mellitus is a serious condition in which your body’s blood glucose or blood sugar levels are above the normal range. According to the American Diabetes Association, 30.3 million Americans have diabetes—that was in 2015, and the number is expected to rise by 2050.  

​To understand diabetes more and the tests needed to detect it, we have to discuss the hormone behind the production and control of glucose: insulin.  



Insulin is one hormone produced in the pancreas with the important role of facilitating m​​​​etabolism, or converting the food we eat into energy.

By using pregnenolone cream or pregnenolone supplements, the levels of the compound in the body increases, and this brings about various benefits such as fatigue relief, and delay of the aging process.

​What Is Insulin and What Does It Do?

​Hormones play a very important part in our lives, and an imbalance can trigger a number of diseases. Insulin is one hormone produced in the pancreas with the important role of facilitating metabolism, or converting the food we eat into energy.

During or after a meal, as the digestive tract breaks down food rich in carbohydrates like pasta and bread, glucose is produced. Glucose and insulin are then transported into our bloodstream and used to fuel cells in the body’s various regions.

​Insulin also maintains glucose homeostasis. When needed, insulin lowers glucose levels by reducing glucose production and when there is an excess of glucose not transformed into energy, the hormone signals the liver to store the extra in the form of glycogen.


​What Happens When My Body Lacks or Resists Insulin?

​Diabetes is commonly associated with insulin resistance and insufficient insulin production. Insulin resistance happens when the cells do not respond to the hormone and an excessive amount of glucose (termed as hyperglycemia) stays in the bloodstream.

There are two main kinds of diabetes: type 1 and type 2. The first type is rare, as it occurs only in 10% of the known diabetes cases worldwide and is usually caused by the lack of insulin in the body.

​On the other hand, prediabetes (or metabolic syndrome) is a precursor to type 2 diabetes, occurring in 90% of people who have the disease. People with type 2 diabetes have insulin resistance, causing their blood glucose levels to increase abnormally despite plasma insulin staying elevated.

Insulin resistance is also the culprit of risk factors like obesity, polycystic ovary syndrome (PCOS), heart attack, and hypertension. Hyperinsulinemia, which is the condition where there are high amounts of insulin in the body, causes hypoglycemia (low blood sugar) with symptoms of seizure, palpitations, and disorientation.

​Also, note that diabetes itself makes it more likely for diseases like colorectal adenoma to develop—and it’s even believed that Alzheimer's disease is essentially a previously unknown form of diabetes.

What Are The Symptoms of Diabetes?

​Symptoms from impaired glucose processing are often not detected early on until diabetes has progressed and complications develop. However, some identifiable symptoms include the following:

  • ​​Having dark patches on the elbows, knuckles, and neck
  • ​Weight loss or excessive weight gain
  • ​Blurred vision and fatigue
  • ​Increased urge to urinate

What Blood Tests Can Be Used for Detecting Diabetes?

​Make sure to speak with your doctor first before getting a blood test or any laboratory work (including those we’ve listed below).

  • 1. A1C or blood glucose test shows blood glucose levels for the past three months. A result of less than 5.7% means normal, while 6.5% and above indicates the presence of diabetes.
  • 2. Fasting glucose test or fasting plasma glucose test, measures glucose in people who have fasted for at least seven to eight hours. A fasting blood glucose between 100mg/dl and 130 mg/dl indicates prediabetes or diabetes.
  • ​3. The Oral Glucose Tolerance Test (OGTT) spans for two hours and checks the levels of blood glucose after consuming a sweet beverage. A result of at least 200 mg/dl means you’re diabetic.

​However, these tests only reveal a few pieces of the puzzle. Fasting insulin tests show you the big picture.


​A fasting insulin test, or knowing your fasting insulin level, will help you save time and resources as it shows you if your body’s insulin is working normally.

By using pregnenolone cream or pregnenolone supplements, the levels of the compound in the body increases, and this brings about various benefits such as fatigue relief, and delay of the aging process.

​Why Is the Fasting Insulin Test Important? 

​Since the tests stated earlier only show you the amount of glucose in your body, it’s highly suggested that you take a fasting insulin test as both fasting blood sugar and plasma glucose levels only rise after a drop in insulin secretion (fasting serum insulin) and with resistance to the hormone itself.

This fasting insulin blood stop test from ZRT Laboratory is an excellent, simple, and accurate home kit that will help identify if you have poor insulin response. Results are kept confidential and arrive within a week after the samples are received at the laboratory.

​What Do I Need to Do to Manage My Insulin Levels?

Once you have taken a fasting insulin test along with other laboratory tests, you have to continuously maintain a healthy lifestyle which involves the following:

  • Lessening Your Consumption of Sweet Food

    In a study, it was revealed that even artificial sweeteners can raise insulin levels. Drastically lowering the amount of sweets you eat in a day can help your insulin to go back to normal.
  • Taking the Right Keto Vitamins or Supplements

    Vitamin D is said to maintain normal blood glucose levels as a deficiency can lead to poor insulin sensitivity. There are great supplements for those whose glucose levels are below average.

    Contact your healthcare provider to know more about supplements that prevent you from becoming insulin resistant and developing diabetes.
  • Getting a Good Night’s Sleep

    Research has shown that those who encounter sleep problems have a higher risk of insulin resistance and may even develop PCOS. Turn off your electronic devices an hour or two before going to bed.
  • Staying Physically Active

    Time and time again, exercise has been an effective method to becoming healthier. Physical activities help people control glucose levels, blood pressure, and cholesterol levels.

    High-intensity interval training (HIIT) is a good option. Basically, this rigorous exercise involves repeated sprinting followed by a cool-down phase.
  • ​Eating Healthily

    ​Following an eating plan called Dietary Approaches to Stop Hypertension or DASH has been proven effective in reducing the effects of insulin resistance.

    ​DASH will require you to eat fruits, vegetables, fish, poultry, and whole grains, while limiting your consumption of sugar-rich food and drinks and fatty meat. With the diet, you’ll be raising your high-density lipoprotein while limiting its counterpart—low-density lipoprotein.

​Act Today to See How Healthy You Really Are

​It’s apparent that lifestyle is a key factor in the occurrence of diabetes and insulin resistance. Unless we change our way of living, our hormones will become imbalanced—and this will eventually affect our quality of life.

​Normal insulin levels indicate a healthy you. Be sure to get a fasting insulin test to see where you truly stand when it comes to overall health.
