Symptoms of pseudopolycythemia?

summary

Polycythemia refers to the number of red blood cells and hemoglobin in unit volume of blood higher than the reference value. The red blood cell count of adult male was more than 6.0 × 1012 / L, hemoglobin > 170g / L, red blood cell count > 5.5 in adult women × 1012 / L, hemoglobin > 160g / L is considered to increase. Polycythemia can be divided into relative and absolute polycythemia, and the latter can be divided into primary and secondary polycythemia. Primary can be divided into congenital and acquired, the latter usually refers to polycythemia vera. Symptoms of pseudopolycythemia? Let's talk about it

Symptoms of pseudopolycythemia?

Pseudohyperkalemia is rare in clinic. It mainly refers to that the actual blood potassium level of patients is not high, but the detection of serum potassium is increased due to the destruction of blood cells and other reasons. If the concentration difference between serum potassium and plasma potassium ion is more than 0.4mmol/l, and the patient has no symptoms, signs and ECG manifestations of hyperkalemia, it is diagnosed as pseudohyperkalemia [1].

At present, the clinical platelet count is mostly completed by automatic cell analyzer, but due to its specific physiological characteristics, the number of platelets is easily affected by many factors, such as sample agglutination, insufficient sample size, sample dilution, cold agglutination sample, self agglutination sample, small red blood cells, cell debris, large platelets, etc. Among them, EDTA dependent pseudothrombocytopenia (edta-ptcp) is the most common. EDTA can also lead to platelet activation, promote platelet and fibrinogen agglutination, hematology analyzer mistook these agglutinated platelets for white blood cells, resulting in the false test results of hematopenia and white blood cell increase [4].

When the fasting blood glucose of adults is lower than 2.8 mmol / L, it is called hypoglycemia. Sympathetic nerve excitation and brain cell hypoxia may appear, such as dizziness, palpitation, sweating, disturbance of consciousness, etc. Leukemic pseudohypoglycemia is defined as the peripheral venous blood glucose concentration of leukemic patients is lower than 2.8 mmol / L but without related symptoms. After the application of effective chemotherapy, with the decrease of white blood cell count, the venous blood glucose value of patients can return to normal [6].

matters needing attention

In short, in clinical practice, we should analyze the examination results that are inconsistent with the symptoms and signs of patients, so as to avoid the false examination results leading to the wrong treatment plan.
