Mononuclear cell ratio (MONO%)

The monocyte ratio (MONO%) is a type of white blood cell differential count, which refers to counting monocytes and performing a percentage calculation. The proportion of single mononuclear cells is high, it is not easy to judge the cause, and it needs to be combined with the condition analysis. Basic Information Specialist classification: cardiovascular examination classification: blood examination Applicable gender: whether men and women apply fasting: fasting Tips: Keep a normal mindset. Normal value Reference value: 3-10%. Clinical significance First of all, it is necessary to manually classify under the microscope to determine whether the monocytes are really high. The monocytes of infants and children can be higher than 8%. If only the proportion of mature monocytes is high, most of them are specific infections. This requires a combination of medical history, and pay attention to physical examination to see if there are any positive signs, etc., comprehensive judgment; if there are naive monocytes, must be further examined, including bone marrow cytology. The reason for the high incidence is found in certain bacterial infections, monocytic leukemia, lymphoma, myelodysplastic syndrome, and recovery period of acute infectious diseases. The reason for the low level has no important clinical significance. High results may be diseases: myelodysplastic syndrome, elderly myelodysplastic syndrome, chronic myelomonocytic leukemia, myeloid monocytic leukemia The classification of white blood cells is greatly changed by factors such as technical factors and cell distribution factors, so the dispersion of classification counts is large, and the proportion of neutrophils and lymphocytes, which account for a large proportion in the classification, is normally distributed, accounting for a small proportion. Such as eosinophils, basophils and monocytes are Powson distribution. Inspection process 1. Take a small drop of blood on one end of the slide, and use a pusher to tilt the surface around 35° to 45° to leave a proper amount of voids to separate the thin blood of the head, body and tail. The length of the blood film is not less than 2.5 cm, and the remaining space to the other end of the slide is about 1 cm. The blood film is dried and stained. 2, Wright's Giemsa composite staining method: flat blood on the staining rack, add 3 to 5 drops of staining solution, immediately cover the blood film, add about 5 to 10 drops of buffer after about 30s, gently shake the slide Or gently blow the mixture to mix the dye solution with the buffer. After 5 to 10 minutes, rinse the dye solution with water and dry it for microscopic examination. 3, fast method: the rapid dyeing liquid A liquid, B liquid respectively in the appropriate size dyeing cylinder, the blood film first immersed in the liquid for 30s, washed, then immersed in the liquid for 30s, washed, after drying, microscopic examination. 4, microscopic examination: select the junction of the end of the blood film body, the red blood cells have not overlapped with oil mirror inspection, the inspection should have a certain direction up and down, and take into account the long edge of the long film diameter, otherwise affect the various types of cells The detection rate. Count 100 to 200 white blood cells, classify them according to their morphology, and find the percentage. Not suitable for the crowd 1. Patients who have taken contraceptives, thyroid hormones, anti-inflammatory drugs, steroid hormones, etc., may affect the results of the examination, and patients with a history of medications of the above drugs are prohibited from being examined. 2, special diseases: patients with hematopoietic function to reduce disease, such as leukemia, various anemia, myelodysplastic syndrome, etc., unless the examination is essential, try to draw less blood. Adverse reactions and risks 1, subcutaneous hemorrhage: due to pressing time less than 5 minutes or blood draw technology is not enough, etc. can cause subcutaneous bleeding. 2, discomfort: the puncture site may appear pain, swelling, tenderness, subcutaneous ecchymosis visible to the naked eye. 3, dizzy or fainting: in the blood draw, due to emotional overstress, fear, reflex caused by vagus nerve excitement, blood pressure decreased, etc. caused by insufficient blood supply to the brain caused by fainting or dizziness. 4. Risk of infection: If you use an unclean needle, you may be at risk of infection.
