摘要:目的 探討血小板直方圖在血小板計數中的應用價值。方法 對173例同時用電阻抗法和光學法檢測血小板的患者結果進行相關性分析;血小板直方圖正常與異常兩例患者比較分析。結果 血小板直方圖正常時,電阻抗法血小板計數結果可靠,且與光學法相關程度強;血小板直方圖異常時,電阻抗法血小板計數結果不可靠,且結果不穩定、忽高忽低,與光學法相關程度弱。結論 據檢測原理分析,光學法較電阻抗法準確性高,但由于檢測成本高故而血小板直方圖在血小板計數中起到篩選不可靠結果的關鍵作用,如為異常圖形,則用光學法復檢。

Abstract:Objective To discuss the application value of platelet histogram in platelet count. Methods 173 cases with resistance method and optical method at the same time of the platelet patients with correlation analysis; Platelet histogram normal and abnormal two patients comparative analysis. Results Platelet histogram normal, resistance method platelet count results are reliable, and optical method related degree is strong; Platelet histogram anomaly, resistance method platelet count results is not reliable, and the result is not stable, fluctuation, and optical method related degree is weak. Conclusion According to the detection principle analysis, optical method more than resistance method accuracy is high, But due to the high cost of testing so platelet histogram in platelet count a screening not reliable results plays a key role, such as abnormal graphics, the optical method review.

血小板計數,指單位體積血液中所含的血小板數目。血小板減少是臨床引起出血常見原因,是外科術前必做檢驗項目之一;還對血栓及出血性疾病的診治起著決定性作用。血小板計數結果準確、穩定,是臨床對檢驗科的基本要求。如何才能做到準確、穩定,現就本院2016年6~7月173例住院病人兩種方法檢測血小板結果進行分析,總結如下。
1資料與方法
1.1一般資料 2016年6~7月173例同時用電阻抗法和光學法檢測血小板的住院患者,受檢者早晨空腹,用EDTAK2真空抗凝管采血。
1.2儀器與試劑 SYSMEX XT-2000i 全自動血球分析儀及配套試劑。
1.3統計學方法 兩組變量之間的密切程度,作相關性的統計分析。
2結果
173例住院患者電阻抗法和光學法檢測血小板結果相關性分析,如圖1。
相關系數0.7421,且明顯見一離群值,剔除后再作相關性分析,如圖2,相關程度明顯增強,相關系數接近1。……
