Diabetes Testing

Why Order Diabetes Tests Online?

Diabetes is a disease that occurs when your body becomes unable to metabolize sugar properly. This failure to manage sugars stems from issues with insulin, a hormone produced by the pancreas. Insulin helps your body use sugars as energy, carrying it into cells throughout your body.

At Health Testing Centers we make diabetes testing easy by allowing you to avoid the hassle of visiting your doctor. We provide diabetes tests, including Doctor's oversight, using the same labs that your doctor utilizes. Test results show your levels compared to a normal range. Test results are securely delivered to you, saving you time and money.

 Fast, accurate, clear lab results without doctor visit
 100% satisfaction guarantee

What are the types of diabetes?

The American Diabetes Association (diabetes.org) lists the most common types of diabetes as:

  • Type 1 diabetes – In this diabetes type, the body becomes unable to make insulin at all, which occurs as the body's own immune system attacks and destroys insulin-producing cells in the pancreas. Type 1 diabetics must take insulin daily to survive. Type 1 is most often diagnosed in children and young adults, but can occur at any age.
  • Type 2 diabetes – In type 2 diabetes, the body doesn't make enough insulin or doesn't use insulin well. Type 2 diabetes occurs most often in people who are middle-aged or older, but is also diagnosed in a growing percentage of younger adults and children.
  • Gestational diabetes – this is diabetes that occurs in pregnant women and, in most cases, goes away after childbirth.

According to the diabetes type a person has, the pancreas may fail to make to insulin to serve this purpose, stop making insulin altogether, or insulin resistance can occur, where the body becomes less efficient at using insulin. The end result of all of these diabetes types is high blood glucose, which means abnormally high levels of sugar in your blood, as glucose that cannot enter the cells to be used builds up in the bloodstream. Having a high blood glucose level can cause a long list of health problems over time, including:

  • Heart disease
  • Heart attack
  • Stroke
  • Kidney disease
  • Nerve damage
  • Dental problems
  • Vision changes or even blindness

The percentage of the U.S. population affected by diabetes or prediabetes has soared in recent years, a situation that has been described by the Centers for Disease Control and Prevention (CDC)as a public health crisis. According to the National Institute Of Diabetes and Digestive and Kidney Diseases (NIDDK), 12.2 percent of American adults and 9.4 percent of the population as a whole had diabetes in 2015, and about 23.8 percent of those did not know of their condition. An additional 33.9 percent of all U.S. adults and 48.3 percent of adults over the age of 65 had prediabetes in 2015, a condition that places them at high risk for developing diabetes.

Who should be tested for diabetes?

Everyone should have diabetes screening tests as part of routine preventive healthcare. Typically, for people who have average risk levels, testing is recommended at three-year intervals. More frequent testing is generally recommended for people who have known risk factors that increase their odds of developing the disease. These include:

  • A family history of diabetes
  • Being 45 years of age or older
  • Being diagnosed with prediabetes
  • Having African American, Alaskan Native, American Indian, Asian American, Hispanic/Latino, Native Hawaiian, or Pacific Islander heritage
  • Overweight or obesity
  • High blood pressure
  • High triglyceride levels and low HDL (good) cholesterol levels
  • A history of gestational diabetes
  • A sedentary lifestyle
  • A history of cardiovascular disease

What are the symptoms of diabetes?

Many people do experience symptoms as blood glucose levels begin to rise. Among the most common are:

  • Increased or extreme thirst
  • Frequent urination, especially at night
  • Increased appetite
  • Weight loss
  • Fatigue
  • Blurred vision
  • Slow healing/sores that do not heal

However, it is important to note that many people with diabetes have very mild symptoms or none at all, only finding out they have the disease through routine health screenings or as they are diagnosed with diabetes-related health problems.

How is diabetes diagnosed?

Diabetes is typically diagnosed with a series of blood tests. The lab tests most frequently used to make a diagnosis include:

  • Fasting Plasma Glucose (FPG) – this fasting glucose test measures your blood glucose (ketones) after a period of at least 8 hours with no food intake. Glucose blood results greater than or equal to 126 milligrams per deciliter (mg/dL) indicate high blood sugar and possible diabetes.
  • Oral Glucose Tolerance Test (OGTT) – for this test, patients have a blood test to check blood sugar levels, then are asked to drink a sugary beverage. Blood sugar is tested again after 2 hours. Blood glucose levels greater than or equal to 200 mg/dL at the 2 hour test indicate diabetes mellitus (type 2 diabetes).
  • Random Plasma Glucose Test – also commonly called a casual blood glucose test, this blood sugar test can be used to measure blood sugar levels at any time of day. Diabetes is diagnosed when results show a blood glucose level of 200 mg/dL or more.
  • Hemoglobin A1C (hba1c) – the hemoglobin test or a1c test measures glucose attached to red blood cells. This test offers a longer-range view of blood glucose levels, measuring the average blood sugar over the past two to three months.
  • Glucose challenge test - pregnant women typically take this test between 24 and 28 weeks of pregnancy. Fasting is not required for this test. Blood glucose levels of above 135 mg/dL are considered too high and may necessitate an oral glucose tolerance test while fasting.
  • Autoantibodies - these tests measure antibodies that attack healthy tissues and cells by mistake. The presence of autoantibodies is common with type 1 diabetes but not type 2.

Since all but one of the blood tests listed above only show blood glucose levels at one point in time – when the blood sample is taken – in most cases, diabetes blood tests are repeated to confirm a diabetes diagnosis. Exceptions to this rule include glucose test results that show extremely high blood glucose levels or patients who have clear and severe diabetes symptoms. Once a diagnosis of diabetes is made, further tests may be done to aid in controlling diabetes and manage diabetes care. A treatment plan to control diabetes often includes lifestyle changes and medication.
