teardrop red blood cells

Red blood cell morphology (poikilocylosis) refers to the obvious changes in the morphology of red blood cells, which can be teardrop-shaped, pear-shaped, stick-shaped, crescent-shaped, etc., most commonly in megaloblastic anemia. The appearance of red blood cells is teardrop or pear shape and is positively pigmented. Basic Information Specialist classification: cardiovascular examination classification: blood examination Applicable gender: whether men and women apply fasting: fasting Analysis results: Below normal: Normal value: no Above normal: Increased in myelofibrosis. negative: normal. Positive: Found in the blood and bone marrow of myelofibrosis. Tips: Keep a normal mindset. Normal value None (negative). Clinical significance Abnormal result Increase is more common in the blood and bone marrow of myelofibrosis. Need to check the population anemia, asthma and other people. Positive results may be diseases: chronic myeloid leukemia, pediatric erythroleukemia, congestive splenomegaly, primary bone marrow fibrosis Inappropriate people: generally no special population. Pre-inspection contraindications: Red blood cell count decreased from 5 pm to 7 am and after meals, up to 10%, bed rest can be reduced by 5.7% compared with normal activities, so should be considered when evaluating two blood test results Factors such as time, diet and bed rest. Requirements for inspection: Red blood cell count is highly prone to errors. Venous blood collection, long-term ligation of the tourniquet can cause false increase, the pipette is unclean, not accurate, will count or increase or decrease; draw the diluent, now use a manual dosing device, the capacity should be calibrated before use; Try to buy the exact one; count enough when counting. If you pay attention to it, the results obtained by the manual method still have good accuracy and can be used to correct the automatic counter. Inspection process In the process of observing red blood cells from disc shape to mouth shape and finally to spherical shape, the authors measured the changes of red blood cell diameter and central recess diameter and cell thickness, and combined the cell surface morphology and measurement results to divide the lesion red blood cells into 5 sub-categories. Type, namely: the mouth type - bowl type - ball type - mouth ball type - typical sphere, other small amount of abnormal red blood cells (thorny and target red blood cells) are attributed to the distortion type. Not suitable for the crowd Generally no taboos. Adverse reactions and risks Can be infected concurrently.
