In some cases, the testing instrument may be affected by certain factors, resulting in errors in the platelet count.
Different testing instruments may vary in accuracy, especially for very low platelet counts, the presence of malformed platelets or platelet aggregates, the count may be inaccurate and should be reviewed with a microscopic blood smear in context.
In addition, pseudo-thrombocytopenia can be caused by poor bleeding during blood collection or by squeezing the bleeding site. Also, prolonged storage of the specimen, hypermagnesemia, and aggregation of proteins may affect the platelet count.
Whether the platelet count is affected by the testing instrument needs to be determined specifically. If the patient has an abnormal platelet count, it is recommended to seek prompt medical attention and standardized diagnosis and treatment.
