ANALIZA SPORT – Level III

Symptoms, habits, energy intake and results that address the actual question matter for an athlete’s nutrition and recovery. The third level combines a broad laboratory investigation with additional food- and antibody-related components. Inclusion in the package does not mean that every component can confirm the cause of symptoms or determine the optimal diet.

Who the panel is for

• recreational exercisers and athletes whose doctor has recommended targeted laboratory assessment
• people with fatigue or changes in exercise tolerance who need possible health causes clarified
• people who want to compare results over time under agreed conditions
• people who want to discuss their results with a professional before deciding on diet or further tests

What the panel contains and shows

• Blood count and inflammatory indicators: complete blood count (CBC), sedimentation rate and C-reactive protein (CRP). They cover blood cells and indicators that may guide assessment of inflammation.
• Lipids and glucose: total cholesterol, HDL, LDL, triglycerides and glucose. HDL and LDL transport cholesterol in the blood, while glucose shows the sugar level. More about lipids is described under lipid profile.
• Hormones: TSH, thyroid hormones T3 and T4 and their free fractions fT3 and fT4. Cortisol is also included, along with testosterone for men or prolactin for women. Their significance is assessed according to the individual hormone and the circumstances of blood collection.
• Minerals and iron indicators: calcium, potassium, magnesium, sodium, iron, UIBC, TIBC and ferritin. UIBC and TIBC describe iron-binding capacity, while ferritin helps assess iron stores.
• Kidney and metabolic indicators: urea, urate and creatinine. They concern metabolic products and their elimination from the body.
• Enzymes and bilirubin: total bilirubin, AST, ALT, creatine kinase, GGT, LDH and alkaline phosphatase (AP). Enzymes are found in different tissues, so their abnormal levels do not have one common cause. The abbreviations AST, ALT, GGT and LDH refer to individual enzyme tests.
• Vitamins and related indicators: vitamin D, vitamin B12, folate and homocysteine. They are used in targeted assessment of vitamin status and related metabolic circumstances.
• Urine: dipstick and sediment examination. It includes chemical indicators in urine and examination of its sediment.
• Food intolerance 211: an additional component of the package. The method and its limitations need to be clarified.
• Candida IgG and Candida IgM: antibody tests. Antibodies alone are not enough to attribute symptoms to candidiasis or prescribe a diet.

Preparation and sample

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

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

How to interpret the result

Low ferritin may indicate reduced iron stores. It is assessed alongside the blood count and other iron indicators. Raised ferritin, however, can accompany inflammation and is not automatically evidence of excessive stores.

Creatine kinase can rise after intense training because it is released from muscle. Recent exertion, muscle symptoms and trends over time matter when assessing such a result, rather than just a single out-of-range flag.

Glucose, lipids and hormones address separate health questions. Their abnormal levels are not a single assessment of fitness, and the required training intensity cannot be calculated from one package.

Candida antibodies can also be found in healthy people. A positive IgG or IgM result alone therefore does not establish that digestive symptoms or fatigue are caused by active candidiasis.

If the food test is based on specific IgG antibodies, the result does not confirm food allergy or intolerance. Such tests are not recommended for making those diagnoses. Do not exclude major food groups based on such a result alone.

Which sports programme should you choose?

An overview of the different levels is available on the sports programmes page. Compare the actual tests and services included, rather than just the level number.

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