ANALIZA SPORT – Level I

When assessing laboratory markers alongside regular physical activity, it is important to know what each result can show. This programme combines blood and urine tests across several areas. It can support discussion of health and further investigation, but does not measure sporting ability or guarantee better training results.

Who is this panel for

• recreational exercisers and athletes whose doctor has recommended targeted laboratory assessment
• people with fatigue or changes in exercise tolerance in whom possible health-related causes need clarification
• people who want to compare results over time under agreed conditions
• people who want an expert discussion of results before deciding on diet or further tests

What the panel contains and shows

• Blood count and inflammatory markers: complete blood count (KKS), ESR and C-reactive protein (CRP). These cover blood cells and markers that may guide assessment of inflammation.
• Lipids and glucose: total cholesterol, HDL, LDL, triglycerides and glucose. HDL and LDL transport cholesterol in blood, while glucose shows blood sugar levels. Read more about lipids under lipid status.
• Hormones: TSH, thyroid hormones T3 and T4 and their free fractions fT3 and fT4. Cortisol and testosterone for men or prolactin for women are also included. Their significance is assessed according to the hormone and sampling circumstances.
• Minerals and iron markers: calcium, potassium, magnesium, sodium, iron, UIBC, TIBC and ferritin. UIBC and TIBC describe iron-binding capacity; ferritin helps assess stores.
• Kidney and metabolic markers: urea, urate and creatinine. These relate to metabolic products and their elimination from the body.
• Enzymes and bilirubin: total bilirubin, AST, ALT, creatine kinase, GGT, LDH and alkaline phosphatase (AP). Enzymes occur in different tissues, so abnormalities do not have one shared cause. AST, ALT, GGT and LDH are abbreviations for individual enzyme tests.
• Vitamins and related markers: vitamin D, vitamin B12, folate and homocysteine. These are used for targeted assessment of vitamin status and related metabolic circumstances.
• Urine: dipstick and sediment. This covers chemical urine markers and examination of urine sediment.

Preparation and sample

The programme includes blood and urine analyses. Plan sampling separately from intense training. You will receive fasting and urine preparation instructions when booking.

State when you last trained intensively and which medicines and supplements you take. Recent exertion can change some blood markers, particularly creatine kinase, so this information matters when comparing results.

How results are interpreted

Low ferritin may suggest reduced iron stores. It is assessed alongside blood count and other iron markers. High ferritin, however, may accompany inflammation and is not automatically evidence of excessive stores.

Creatine kinase may rise after intense training because it is released from muscles. When assessing this result, recent exertion, muscle symptoms and trends over time matter, not just one out-of-range flag.

Glucose, lipids and hormones address separate health questions. Their abnormalities do not form a single fitness score, and one package cannot determine the required training intensity.

Which sports programme should I choose?

An overview of the different levels is available on the sports programmes page. Compare the actual tests and services included, not just the level number.

If you need a different scope of laboratory investigation, you can explore Fitness Plus. For a sports medical examination, see the sports examination options and check what the examination includes. A laboratory package alone does not replace a medical examination.

How to arrange testing

You can book a SPORT programme at one of our branches throughout Croatia (listed on the Contact). State your selected programme level to arrange an appointment and receive preparation instructions.
