BLOOD COLLECTION AND BLOOD TEST
Blood tests are recommended to be conducted for preventive purposes once a year until one is 50, after that, every six months. Different metabolic and other disorders that occur in the body may be detected in blood tests. Everybody has its own specific enzymes, proteins or other organic molecules. As the blood system passes through all the organs, provides food to the cells and eliminates unnecessary and harmful products of the metabolism, any change in an organ(s) will be reflected in the blood circulation with the change in the concentration of enzymes, proteins, electrolytes, etc.
BIOCHEMICAL ANALYSIS AND BLOOD EXAMINATION
After collecting blood in different tubes with or without anticoagulant (e.g. the blood count requires EDTA anticoagulant, whereas most biochemical analysis need blood coagulation to obtain serum on which most analyses are conducted), blood/serum is analysed in different machines depending on the group of analyses. The main metabolic parameters (glucose, fats, proteins, enzymes) are determined with biochemistry analyzers which operate on the principle of photometry/spectrophotometry, while hormones and tumor markers are determined with immunochemistry analyzers. Their determination is mostly based on At-Ag reactions. The blood count with a differential leukocyte formula is determined with hematology analyzers, whose operation is based on different principles (ranging from potentiometry to flow cytometry, etc.) Most biochemistry analyses in Beo-lab are conducted with the most advanced integrated biochemistry autoanalyzer by ABBOTT company.
BLOOD COUNT ANALYSIS
A complete blood count analysis most often implies the blood count performed on the hematology analyzer. Today there are different hematology analyzers with at least 8 parameters to more than 20 parameters in the blood count analysis. To gain a general overview and control of the blood count, it is sufficient to conduct an analysis on the hematology analyzer with 8 parameters. Anemia or other hematological diseases require a hematological analyzer with more than 8 parameters.
INTERPRETATION OF LABORATORY AND BIOCHEMICAL BLOOD FINDINGS (RESULTS)
Interpretation of biochemical findings at a personal request will be provided by a Beo-lab specialist. Interpretation of biochemical results is a responsible and complex obligation of a specialist, and it requires a detailed analysis of every pathological finding.
BLOOD COUNT INTERPRETATION
Blood count interpretation, also at a personal request of the patient, will be provided by Beo-lab specialists. Blood count results reflect the number of blood cells in the bone marrow, and their ratio in blood circulation. The number of blood cells (leukocytes, erythrocytes and platelets) as well as the concentration of hemoglobin, hematocrit and other blood count parameters affect interpretation of the blood count.
REFERENCE VALUES OF BLOOD, BLOOD COUNT AND OTHER BIOCHEMICAL PARAMETERS
Reference values (an earlier term “normal values”) of the blood count and biochemical analyses are predetermined ranges of concentrations of every parameter separately, depending on the gender and age of the patient as well as on reagents and devices used in the analysis. Every laboratory is required to indicate reference values depending on reagents and devices used.
LABORATORY URINE FINDINGS
A laboratory urine finding may have several meanings depending on the present urine parameters. The finding may be normal, which means that the analysed urine parameters are within the normal range. Also, the finding could be pathological according to a parameter (e.g. more than 5 leukocytes or erythrocytes are present, or positive glucose or hemoglobin in urine is found, etc.).
