Pediatrik Yaş Grubunda Trombosit İndisleri

Trombosit indisleri olan ortalama trombosit hacmi, trombosit hematokriti ve trombosit genişlik dağılımı, klinisyenler tarafından çok da dikkate alınmayan parametrelerdir. Her ne kadar bazı hastalıklarla ilişkileri belirtilmişse de, henüz tam bir tanı değeri bulunmamaktadır. Amacımız, trombosit parametrelerini 6 ay-18 yaş arası çocukluk çağı yaş grubunda dağılımlarını belirlemektir. Elde ettiğimiz veriler, trombosit sayısının artmasıyla, trombosit hematokrit değerinin arttığını r = 0.91, p

Thrombocyte Indices in Pediatric Age Group

Platelet PLT indices mean platelet volume MPV , platelet hematocrit PCT and platelet distribution width PDW are probably the most ignored parameters by the clinicians. Although several studies held among different disease states, they do not have diagnostic value yet. Our aim was to determine the reference range of platelet parameters in venous blood samples of a population with an age range 6 months to 18 years in a hospital laboratory. This retrospective study consisted of 710 healthy children and the subjects were categorized into five groups according to their age. Age distribution of these groups was 6 months; 12 months; 18 months; 2-5 years and 6-18 years respectively. Our data revealed significant differences with regard to the MPV, PCT and PDW among the groups p
