[An Accurate Diagnosis is Possible with a Systematic Analysis of Routine Laboratory Data].

Routine laboratory tests are ordered for almost all in- and outpatients. A systematic analysis of routine laboratory data can give doctors valuable clinical information about patients. In some cases, a correct diag- nosis can be made using laboratory data alone. In our laboratory, we use five processes to evaluate routine laboratory data. Firstly, we estimate the patient's general condition based on A/G, Hb, TP, Alb, ChE, and platelet (PLT) levels. Secondly, we look for inflammation and malignancy based on WBC, CRP, PLT, fibrinogen, and ESR levels and the protein electrophoresis pattern. Thirdly, we examine the major organs, especially the liver and kidney. We check the liver for hepatocyte damage, obstruction, hepatic synthetic function, infection, and malignancy. We estimate GFR and check the kidney for any localized damage. We then check the chemistry, hematology, and immunology. Finally, we form a conclusion after a comprehensive interpretation of the above four processes. With this systematic approach, any members of the laboratory unit can easily estimate the exact pathological status of the patient. In this case study, marked change of TP indicated non-selective loss from the skin; namely a burn. Tissue injury and infections due to different focuses were the most likely causes of severe inflammation. Neither the liver nor kidney was severely damaged. Continual bleeding and hemolysis through the clinical course probably caused anemia. Hypooxygenic respiratory failure and metabolic alkalosis were confirmed by blood gasses. Multiple organ failure was suggested.
