title: Platelet X-ray microanalysis in patients with chronic renal failure.
abstract: The platelet element content was determined by semiquantitative X-ray microanalysis in 6 patients with chronic renal failure. The patients showed a different degree of thrombocytopathy expressed by impaired adhesiveness, epinephrine-induced aggregation and platelet factor 3 availability. The microanalysis indicated significantly increased quantities of phosphorus and copper in patients' platelets. Sodium and zinc showed a decrease in about half of the patients, whereas iron was significantly increased in at least 50% of the patients. Magnesium and potassium did not show any difference from the control. The results of sulfur, chlorine and calcium did not reveal a consistent pattern.
