السلام عليكم
-مشكله الحالات الى فيها نسبه دهون عاليه
(Lipemia )
بتأثر فقط على نتيجة ال هيموجلوبين ومالوش تأثير على عدد
RBCs ,WBCS ,Platelets
بس بيأثر على نتيجه
MCV , MCH , MCHC
لأن دول بيعتمدوا ف الاصل على نتيجه الهيموجولبين الى حتطلع غلط ...
الحل ايه :-
-عن طريق استبدال ال بلازما ب محلول الملح
طريق الشغل انك بتفصل العينه كويس خالص وبتشيل البلازما وبتحط نفس الكميه من محلول الملح وتعيد قرايه العنيه تانى ..
الطريقه دى مش حتأثر على اى حاجه غير بس ممكن الصفائح تقل شويه نتيجه انك سحبتها مع البلازما ... وفى الاخر يفضل دائما طلب عينه تانيه ويفضل تيجى الحاله صايمه .
دمتم بخير ..
Lipemia interferes with the accurate determination of hemoglobin, or Hb, by spectroscopy on most hematology analyzers, but it does not generally interfere with determinations (especially impedance based) of red blood cell count, white blood cell count, and platelet count. Since hematology analyzers measure mean cell volume, RBC, and Hb, and determine hematocrit, mean cell hemoglobin, and mean cell hemoglobin concentration, an inaccurate Hb affects the hematology result and those derived from it.
When lipemia interferes with hemoglobin determination, multiple approaches are commonly used to report the complete blood count. The first is to report only the hematocrit, RBC, MCV, WBC, and platelet count and indicate that an accurate Hb is not available due to lipemia, and suggest repeating the tests after the patient has fasted at least two to three hours. This approach is often sufficient if the ordering physicians are only interested in the WBC or platelet count. If they want to rule out anemia, the RBC and hematocrit determinations are sufficient.
