Glycated Haemoglobin A1c (Hb A1c)
Oral Glucose Tolerance test (OGTT)
Diabetes Health Screening
Those at risk to develop Diabetes Mellitus (DM) should be tested. If you have a sedentary lifestyle, have obesity (especially abdominal obesity), have a first-degree relative with diabetes, have hypertension, have heart disease, have high cholesterol profile, are a woman who developed gestational diabetes during pregnancy, women who delivered a baby weighing more than nine pounds, or are of a high-risk ethnic population such as African, African/American, etc). Moreover, anyone over age 45 is advised to test for DM.
This screening package includes:
Glucose: this is the most direct test to discover DM. The test measures the level of glucose in the blood.
Glycated Haemoglobin A1c (HbA1c) evaluates the average amount of glucose in the blood over the last two to three months. Glucose in the blood binds to proteins like haemoglobin producing glycated haemoglobin (HbA1c): the higher the amount of glucose in the blood the higher the amount of HbA1c. The combination of the HbA1c result and the glucose result provide a good indication of your body’s glucose metabolism. In addition, for a person with DM, HbA1c levels are directly related to the risk for complications of DM.
The Oral Glucose Tolerance Test (OGTT) “challenges” the person’s body to process the glucose and checks how your body metabolizes sugar. Normally, the blood glucose level rises after the drink and stimulates the pancreas to release insulin into the bloodstream. Insulin allows the glucose to be taken up by cells. As time passes, the blood glucose level is expected to decrease again. When a person is unable to produce enough insulin, or if the body cells are resistant to its effects (insulin resistance), then less glucose is transported from the blood into cells and the blood glucose level remains high.
Lipids tests include cholesterol, HDL “good cholesterol”, LDL “bad cholesterol”, VLDL and triglycerides. This group of tests help to assess the risk of atherosclerosis and of developing heart disease, stroke or related cardiovascular diseases. People with DM have an increased prevalence of lipid abnormalities that require management to prevent the development and progression of vascular complications.
Urinalysis: consists of a set of chemical, microscopic and macroscopic analysis that can detect some common diseases. It may be used to screen for and/or help diagnose conditions such as urinary tract infections, kidney disorders, liver problems, diabetes or other metabolic conditions.
Common signs and symptoms of DM are increased thirst, increased urination, increased appetite, weight loss, fatigue, recurrent urine infections, blurred vision, numbness, tingling, and pain in the feet.
The cases of DM are increasing worldwide with type 2 accounting for 90% of all cases. This increase in DM is driven by rising levels of obesity and an ageing in the population.
Prevention, identification of those at risk of developing DM and early detection can reduce the prevalence, the complications and the impact on the life expectancy and quality of life of the patients. It’s estimated that up to 50% of all patients with DM type 2 are undiagnosed as they remain asymptomatic for many years well after complications such as kidney failure; vision problems, leg or foot numbness and vascular disease of the heart and brain have developed.
Unless you are diabetic or pregnant, we recommend that you fast (not eat any food) for at least 8-10 hours. Do drink water while fasting and continue with any prescribed medications following your doctor instructions. Ideally, you should be on a stable diet for two weeks prior to the taking of the blood sample. If you have any question, contact us and we will let you know how to prepare for your blood tests.
A small amount of blood will be drawn by trained staff from a vein in your arm using a needle. The procedure is quick and easy. Rarely, some people may feel faint or dizzy while having the blood taken and you may need to lie down to help you to feel better. The procedure may cause some minor discomfort and a small bruise may develop in the area where the needle was inserted. Press over the site where the needle was inserted, keeping your arm straight to reduce the likelihood of bruise formation. If you develop redness or inflammation in the same area, seek your doctor for advice.
A urine sample is required for this test which should be taken first thing in the morning. We can provide you with a container. Please write your name, date of birth, and date and time of the sample taken on the container and bring it to us for examination.
An abnormal finding may (but not necessarily) indicate a problem that needs to be addressed. We recommend that any abnormal result should promptly be consulted with your GP. Your doctor will evaluate the test results in the context of an overall clinical picture that takes into consideration your age, gender, ethnicity, family history, signs, symptoms, etc.
