Analysis Of Completeness Of Blood Vacuume Tube Filling At A Clinical Laboratory

Abstract

Background: Overfilled and under filled tube are most important cause of pre-analytical error and failure to complete requested examination in sample. The study was performed to analyse relationship between time of receiving of sample, location of sample, type of vacuum tube, method of collection, total volume required in a patient and volume incompleteness. Material And Methods: The study involved collection and patient samples data, i.e. receiving time of sample, place of collection, type of vacuum tube, blood collection method, total volume required in a patient, measurement of volume before processing. Average incompleteness of vacuum tube was calculated and average relationship between incompleteness and these parameters done.Result: Average incompleteness in OPD samples is better than Non-OPD samples. Average incompleteness is better during 9 am to 12 am than early morning hours. Incompleteness with relation to vacuum tube type is in general Plain > (EDTA/Fluoride) > Citrate. Average incompleteness better in sample collected with vacuum tube needle with holder than use of syringe. Average incompleteness increases as total volume required in a patient increases. Conclusion: Dedicated phlebotomist and use of vacuum tube needle with holder is required to bring overall improvement in completeness of blood collection.
