title: VARIATIONS OF THE PLATELET COUNT IN DISEASE.
abstract: Platelet counts were obtained in 675 patients with different hematological and other medical disorders. An indirect venous blood dry slide method which gave a normal range of 200 to 400 x 10(3) per cu mm was used. Platelet counts varied considerably in disease: In 20 patients, exclusive of myeloproliferative disorders, platelet counts in excess of 1,000 x 10(3) per cu mm were observed; in 20 patients, exclusive of leukemia and megaloblastic anemia, platelet counts were below 100 x 10(3) per cu mm. In general, platelet counts varied with the leukocyte count, but not with the degree of anemia.
