LounaLab service will close June 18th. As of today, products can no longer be purchased there.

All purchased appointments and test results are safe and are available here until the stated date, then transferred to the current SYNLAB service. For more details see the news or contact our representative.

S -Trigly

S -Trigly

The human body contains reserved lipids, triglyceride. The majority of this lipid (fat) is in the fatty tissue but some circulates in the blood, providing energy to muscles, for example. The amount of triglycerides increases after you eat because the fats contained in the food are absorbed from the gut for storage.

When should triglyceride be measured?
  • Overweight
  • Elevated blood pressure
  • Diabetes
  • Low amount of exercise
  • Smoking and genes increase the risk of cardiovascular diseases

Triglyceride is measured to estimate the magnitude of the risk. The test is often carried out in connection with a health examination. Triglycerides alone do not indicate the risks. They are usually measured as part of blood lipids or fats (total cholesterol, HDL cholesterol, LDL cholesterol and triglycerides).

What does a triglyceride test measure?

Triglycerides are the fat reserve of the body. The body gets triglycerides from two sources: from food and by producing them itself. The fat contained in food (oils, milk fat, butter, fat in animal meat) is mainly triglyceride fat, which is broken down in the small intestine and absorbed into the bloodstream. Our cells, especially liver cells, can also produce triglycerides. The body transforms the excess energy from carbohydrates and proteins into triglycerides, which are stored in fat cells. The term ‘triglyceride’ comes from Greek words ‘tri’ for three and ‘glykys’ for ‘sweet’.

Blood triglycerides are measured after fasting overnight. Normally, the level of triglycerides in the plasma is below 2.0 millimoles per litre. If the triglyceride value exceeds this threshold, the condition is called hypertriglyceridaemia. That means excess blood triglycerides.

The recommended target value is < 1.7 mmol/l

With regard to triglycerides, target values are used instead of regular reference values.

Please contact your doctor or other health care professional if you suspect an illness or need help interpreting the results.

Elevated triglyceride values occur when the liver produces higher than normal levels of triglycerides or their elimination from blood is slow. Below is a list of typical situations.

  • The most common cause is abdominal obesity and the related fatty liver, associated with disturbances of fat metabolism in the liver
  • High amount of fast carbohydrates (sugar, light grain products) in the diet
  • High alcohol consumption. Drinking a lot of alcohol has a negative effect on liver metabolism.
  • Poorly controlled diabetes
  • Hypothyroidism (underactive thyroid)
  • Hormone replacement therapy (oestrogen) and some antihypertensive drugs can increase the concentration.

Dyslipidaemia is a condition where the blood LDL cholesterol level is elevated (above 3.0 mmol/l), triglyceride concentration is elevated (above 2 mmol/l), HDL cholesterol is low (below 1.0 mmol/l in men, below 1.2 mmol/l in women) or a combination of these.

  • Fat malabsorption from the intestine
  • Malnutrition
  • Hyperthyroidism (overactive thyroid)

LDL cholesterol reflects the risk of cardiovascular diseases (2099 fS-Kol-LDL)

Low HDL cholesterol increases the risk of developing a cardiovascular disease (2097 fS-Kol-HDL)

The risk of coronary artery disease increases as total cholesterol increases (2095 fS-Kol)
