Glucose tests are the primary tests used in the diagnostics of diabetes mellitus and some other diseases.

Diabetes mellitus is one of the most common chronic diseases, and its first symptoms may be not recognised by some patients. Diabetes mellitus is diagnosed for the increasing number of the patients. Diabetes mellitus has affected about 60 million of people in the Europe and even one third of them are not aware about being ill. In Lithuania diabetes mellitus affects one person out of 20. 
Diabetes mellitus is a disease, which develops when the pancreas produces too little insulin – a hormone that regulates blood glucose levels, or when the body is unable to use effectively insulin produced by the body. 

Based on the development mechanism there are two types of diabetes mellitus.

Type 1 diabetes mellitus accounts for 5-10 percent of all diabetes cases. It usually affects children or young people, however it can develop in people of different age. The exact cause of this type diabetes mellitus is still unclear, however it has been suggested that the process is predetermined by genes. The disease manifestation can be provoked by different external factors, such as viral infection, stress and many others. The immune system of a person with type 1 diabetes mellitus starts to fight anf kills the insulin producing pancreatic cells. This is autoimmune diabetes mellitus. As blood insulin levels reduce, blood glucose cannot reach the tissue cells, thus its blood levels increase.

Type 2 diabetes mellitus is found in more than 90 percent of all diabetic patients; this disease is predisposed by obesity, lack of physical activity, life style and genetic predisposition. Type 2 diabetes mellitus is associated with insulin deficiency or its insufficient activity in different body tissues (tissues are resistant to insulin effect). The body tissues assimilate smaller amount of carbohydrates received with food (they are metabolised to glucose in the body). The pancreatic cells are able for some time to maintain normal glucose levels by producing increased levels of insulin. However, eventually pancreatic reserves become reduced and blood glucose levels increase (hyperglycaemia) At the beginning mild hyperglycaemia develops, which later transforms into type 2 diabetes mellitus. Type 2 diabetes mellitus develops gradually and insensibly, the disease may start without any symptoms. Usually diabetes mellitus is diagnosed during prophylactic check-ups or when disease complications develop. 

Glucose tests are recommended if:

  • you have diabetes mellitus,
  • during pregnancy for diabetes prevention,
  • if you are overweighted,
  • your blood pressure is increased,
  • you have increased cholesterol or triglyceride levels,
  • you have family history of diabetes mellitus,
  • glucose test prophylactically should be carried out at least once per year.

Glucose tests should be carried out after fasting up to 8-14 hours before the test. 

Reservation is not required, just come to the Centre and contact the reception.

Why it is worth

To be examined at our Centre?

  • Your tests will be carried out ensuring high quality. This is proved by ISO 15189 accreditation of the laboratory. 
  • The test results obtained in our laboratory will be explained by laboratory professionals.
    Such service in our country is offered only in few laboratories.
  • If necessary, within 7 days after blood collection we can carry out additional tests using the same collected blood sample. This is important for a child or for the patients coming from other cities!
  • There is no risk of damaging or confounding samples during transportation, which is statistically one of the most common causes of sample damage in the laboratories.

Good to know

The most common symptoms are:

  • thirstiness, 
  • frequent urination,
  • uncontrolled weight gain or loss,
  • skin itching,
  • worsened vision,
  • acetone-like breath,
  • permanent fatigue, 
  • urinary tract infections,
  •  hungry even after eating.

If you experience one or several of these symptoms for longer than for several weeks without any clear reason, we recommend to contact a physician and make some tests.

  • In adults – 3.5–5.6 mmol/l,
  • In children – 2.2–6.2 mmol/l, dependent on age.

If abnormal glucose levels are reported, it is recommended to repeat the test after one month. If elevated glucose levels are again reported, glucose tolerance test is recommended, which will shoe whether you have glucose tolerance disorder or diabetes mellitus.

Glucose tolerance test is carried out for the patients who had abnormal blood glucose values during the prophylactic general blood testing. Glucose tolerance test requires special preparation and it takes relatively long time as it involves two glucose tests with 2 hours interval.

  • You must not fast for 10 days before glucose tolerance test.
  • 3 days before glucose tolerance test you should eat sufficient usual amount of carbohydrates.
  • Usual activity is recommended, however it is recommended to avoid excessive physical activity.
  • Alcoholic drinks should be avoided for 24 hours before the test.
  • A person should stay fasting forc8-14 hours before the test and have a good rest (sleep) overnight. Coffee, tea or other beverages except water should be avoided during this period. 
  • It is recommended to avoid smoking for at least 8 hours before the test.
  • Exercises and smoking are forbidden in the morning before the test. The use of medicines affecting metabolism – hormones, diuretics, hypotensive, psychotropic medicines, corticosteroids, thyroxine, phenytoin and oral contraceptives should be avoided, if possible.
  • The test is carried out at rest, any other procedures are not allowed before the test.

Glucose tolerance test is when fasting blood glucose level is less than 7 mmol/l, but is higher than normal, or in the presence diabetes mellitus risk factors or signs characteristic for diabetes. 

At first fasting blood glucose level is tested; then the patient has to drink 75 g glucose and then after 2 hours blood glucose level is tested again. 

  • If fasting blood glucose level is less than 7 mmol/l, and after 2 hours as well as after the consumption of 75 g of glucose the level is equal to or higher than 11.1 mmol/l, diabetes mellitus should be suspected. 
  • If blood glucose level after the consumption of 75 g of glucose is between 7.8 to 22.1 mmol/l, carbohydrate tolerance disorder is diagnosed. This means that the patient still has no diabetes mellitus, however there is a high probability of the disease, unless nutrition and life style habits are corrected. 
  • If fasting blood glucose level is 6–6.9 mmol/l, and after the consumption of 75 g of glucose and after 2 hours, the level is normal, a fasting glycaemia disorder is diagnosed. 
  • The results of the  tests most frequently carried out will be ready in 1 day.
    You may get them at the reception or we will send them by e-mail, if you wish.
  • For interpretation of the test results please contact the laboratory by telephone: (8 5) 247 64 17.
