This most common laboratory diagnosis helps to detect problems in time and correctly diagnose. The tests differ depending on the purpose or the suspected disease.
General (clinical) – a proven way of collecting information about the whole body for decades. Indicated for preventive purposes, even in the absence of complaints. Allows you to accurately determine where exactly the pathology develops, and to prescribe an accurate treatment. Having studied the indicators of hemoglobin, erythrocytes and platelets, the doctor will be able to identify anemia, inflammation and infections, allergies, neoplasms, diseases of the blood or hematopoietic organs, disorders in the immune system.
Biochemicalwith high accuracy determines malfunctions in the work of internal organs, since any changes are reflected in the chemical composition of the blood. When decoding the results, the doctor will pay attention to protein, pigments (bilirubin), cholesterol. The analysis is prescribed for the diagnosis of liver and kidney function, disorders in the work of the heart muscle (heart attack, stroke), with arthritis, arthrosis, osteoporosis, diabetes, gynecological pathologies and malfunctions of the gastrointestinal tract.
Immunological helps to assess how the body’s defense system works, and also to determine what infections a person has suffered. Indications for appointment: frequent occurrence of infectious diseases; suspicion of an immunodeficiency state; allergic reactions; complications after surgery; autoimmune pathologies.
Hormonal profile allows you to identify diseases before the first symptoms appear. This is because hormones are involved in all metabolic processes in the body. Research is being conducted on the hormones of the thyroid gland, pituitary gland, adrenal glands, and genital hormones. As a rule, they are prescribed for infertility, osteoporosis, obesity.

At any time, you can carry out genetic studies, take a general blood test, as well as tests for blood type, Rh factor, for allergies and infections, for example. It is better to take biochemistry and hormones in the morning.
2. Eating food triggers a series of reactions that can skew the test results. If you are examining hormones or taking biochemistry, you can eat no later than 8 hours before your visit to the clinic. Before donating blood for cholesterol, before testing glucose levels, insulin – 12 hours in advance. It is also better not to drink water. Even if the test does not have to be taken on an empty stomach, the food should be light.
