There are different types of laboratory tests, including blood tests, urinalysis, organ function tests (such as liver, kidney and thyroid tests), microbiological tests analysis (bacteria, viruses, fungi), analysis of hormones and enzyme levels, as well as genetic analysis.

Many blood tests require you to be on an empty stomach (eg 8-12 hours before taking the sample). Also, be sure to inform your doctor if you are taking any medications, as some medications may affect the results.

Some of the most common blood tests include: Complete blood count (CBC) – used to assess general health and detect a wide range of disorders, including anemia and infections.
Liver function tests – they measure the levels of enzymes and other substances produced by the liver, such as ALT, AST, bilirubin.
Kidney function tests – include measurement of creatinine and urea to assess kidney function.
Blood glucose – used to diagnose diabetes.
Lipids (cholesterol) – help assess the risk of heart disease.

Yes, blood glucose testing usually requires fasting for 8-12 hours before the blood is drawn. This allows for accurate results that will not be disturbed by food.

A high level of cholesterol, especially LDL ("loš" cholesterol), can increase the risk of developing heart diseases, such as myocardial infarction and stroke. It is important to monitor cholesterol levels and implement changes in diet or therapy to reduce the risk.

Tests that evaluate thyroid gland function include TSH (thyroid-stimulating hormone), FT4 (free thyroxine), and FT3 (free triiodothyronine). These tests help diagnose disorders such as hypothyroidism or hyperthyroidism.

For urinalysis, no special preparation is usually required, but it is important to take the middle part of the urine (not the first or last part). If it is necessary to do a urine culture, it is recommended that you urinate before š coming for the analysis.

For hormone analysis, the preparation depends on the type of hormone being tested. For example, tests for thyroid hormone (TSH, T3, T4) and stress hormone (cortisol) usually require a blood sample to be taken at a specific time during the day (usually in the morning). Also, be sure to inform the doctor about the medicines you are taking.

For bacterial cultures, a sample is taken from the site of infection (such as the throat, urinary tract or wound) using a special sterile swab or needle. This test helps to identify the bacteria causing the infection, in order to determine the appropriate antibiotic.

Some tests, such as š routine tests such as š a complete blood count, can be done without special advice from a doctor. However, many tests, especially hormone analyzes or organ function tests, usually require a doctor's recommendation, who will interpret the results in the context of your medical condition.

Yes, laboratory test results can be inaccurate for several reasons, including poor patient preparation, sampling errors, use of outdated materials, or analytical errors. . That is why it is important to consult a doctor who will correctly interpret the results.

The waiting time depends on the type of test. For basic blood tests, results are usually available in 1-2 days. Specialized tests, such as hormone analyzes or genetic tests, may take a few days to a week.

CRP test measures the level of C-reactive protein in the blood, which is an indicator of inflammation in the body. An elevated level of CRP may indicate infection, inflammatory diseases or chronic diseases such as arthritis or heart disease.

An increased level of bilirubin in the blood can indicate problems with the liver or gallbladder, such as hepatitis, cirrhosis or obstruction of the bile ducts. Bilirubin is created during the breakdown of red blood cells.

If the test results are abnormal, the doctor will most likely recommend repeating the tests to ensure the accuracy of the results. Also, additional tests may be needed to get a complete picture of your health.
