British Journal of Haematology, 1971
Summary. Modifications of the Technicon S.M.A.4 and S.M.A.4A equipment which substitute automated platelet counting for red cell counting are described. Experimental results are presented which establish the validity and reproducibility of the method and show that the results are quantitatively comaprable to those obtained by manual and semi‐automated

The average number of platelets per oil immersion field, in a count of ten oil fields, multiplied by 20,000 has proved to be a reliable estimation of platelets in normal and thrombocytopenic states. In the presence of thrombocytosis, ie, 25 or more platelets per oil immersion field, the smear count is less reliable.

A technique for electronic platelet counting is described. The erythrocytes in whole blood were removed by sedimentation at 1 × g in a two-phase system, using dextran as the erythrocyte-aggregating agent. The platelets in the plasma layer were counted electronically.

Platelet Count and Platelet Stickiness in Rats
Thrombosis and Haemostasis, 1971SummaryIn rat, a transected tail vessel proved an adequate source of blood for platelet enumeration. When suspensions of rat blood in ammonium oxalate were rotated for 1 h a significant loss of platelets was observed. This platelet reduction rate (PRR), calculated as per cent of the pre-rotation count, showed individual constancy and inter-individual ...

An estimate of the platelet count is usually given as part of the complete blood count (CBC). It should not be neglected when reviewing CBC results as it is a fair screening test and satisfactory for most purposes in the emergency department.

Circulating platelet count and glycans
Current Opinion in Hematology, 2021Purpose of the review This review highlights recent advancements in understanding the regulation of platelet numbers, focusing on mechanisms by which carbohydrates (glycans) link platelet removal with platelet production in the bone marrow in health and disease. Recent findings This

Pediatrics, 1969
The article1 in the October 1968 issue on "Platelets in Prematures" deserves more than a few remarks in the commentary relative to the incidence and hazards of thrombocytopenia. The article is good in that it serves as a guideline relative to the range in platelet levels among premature infants, but the reader should not accept this simply as the ...

The Platelet Count and Mean Platelet Volume
British Journal of Haematology, 1981Summary. The Coulter Model S‐Plus Counter provides a measure of the platelet count and the mean platelet volume (MPV). An analysis of 5000 unselected blood specimens showed an inverse relationship between the number of circulating platelets and their MPV.

Effect of heparin on platelet count and platelet aggregation
American Journal of Hematology, 1987AbstractThe in vitro effect of heparin on platelet aggregation was studied in three groups: in 26 subjects recently treated with heparin, in 18 subjects on maintenance hemodialysis, and in 20 normal controls. With the aid of Technicon H6000, platelet counts and platelet aggregations were compared in whole blood samples collected in ethylenedi ...

The origin of platelet count and volume
Clinical Physics and Physiological Measurement, 1984Platelet count and volume were measured in man (n = 51) and rat (n = 9). Bone marrow megakaryocyte nuclear and megakaryocyte planimetric areas were measured in man (n = 11) and rat (n = 9). Megakaryocyte cytoplasmic volumes were computed from the planimetric areas. Rat had a significantly higher (p less than 0.001) mean megakaryocyte cytoplasmic volume
