“…Nursing staff sometimes fail to recognize the importance of using veins in which IV lines have not been introduced. [ 19 ] It has been suggested that whenever IV fluid is being administered in a patient's arm, blood should be drawn from the opposite arm. If an IV fluid is running in both arms, sample may be drawn after IV infusion is turned off for at least 2 min before venipuncture and applying the tourniquet below the IV infusion site.…”

“…This observation was almost comparable to those of recently published Indian studies [ Table 3 ] which confirm that problems directly related to specimen collection are the main cause of preanalytic errors. [ 6 10 19 ] This can be reduced by competency check of staffs by conducting practical and theory assessment at regular intervals and attending continuing medical education programs related to quality control in hematology.…”

BACKGROUND: An important component of laboratory medicine is preanalytical phase. Since laboratory report plays a major role in patient management, more importance should be given to the quality of laboratory tests. AIM: The present study was undertaken to find the prevalence and types of preanalytical errors at a tertiary care hospital in South India. MATERIALS AND METHODS: In this cross-sectional study, a total of 118,732 samples ([62,474 outpatient department [OPD] and 56,258 inpatient department [IPD]) were received in hematology laboratory. These samples were analyzed for preanalytical errors such as misidentification, incorrect vials, inadequate samples, clotted samples, diluted samples, and hemolyzed samples. RESULTS: The overall prevalence of preanalytical errors found was 513 samples, which is 0.43% of the total number of samples received. The most common preanalytical error observed was inadequate samples followed by clotted samples. Overall frequencies (both OPD and IPD) of preanalytical errors such as misidentification, incorrect vials, inadequate samples, clotted samples, diluted samples, and hemolyzed samples were 0.02%, 0.05%, 0.2%, 0.12%, 0.02%, and 0.03%, respectively. CONCLUSION: The present study concluded that incorrect phlebotomy techniques due to lack of awareness is the main reason for preanalytical errors. This can be avoided by proper communication and coordination between laboratory and wards, proper training and continuing medical education programs for laboratory and paramedical staffs, and knowledge of the intervening factors that can influence laboratory results.

“…The rate of haemolyzed samples was 3% of all tubes received. Similar studies have also reported hemolyzed sample rates of less than 1% [5,[8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24].…”

Pre-analytical errors still represent nearly 70% of all errors occurring in the laboratory, constituting a danger, a waste of time and an additional cost to the patient. The control of the different components of the pre-analytical step is important for the validity of the hemostasis exploration tests. The purpose of our work is to identify the main anomalies of the pre-analytical phase in hemostasis and to propose the means to correct them. We conducted a prospective and descriptive study on the pre-analytical phase of hemostasis. It was in the form of a survey, identifying the main errors related to this phase. It was performed at the Hematology laboratory of the Avicenna Military Hospital of Marrakech and spread over a period of 4 weeks. Our investigation took place at the hemostasis room, which received the collection tubes from the various hospital departments and the blood drawing room (for non-hospitalized patients). The hemostasis room received 400 prescription cards and their corresponding tubes. The parameters related to the prescription file: full name and gender of the patients, were mentioned on all the cards received and they were in conformity with those marked on the corresponding tube. The age of the patients and their clinical and therapeutic informations were mentioned in 73% and 13% of the exam requests, respectively. For the pre-analytical hemostasis parameters related to the blood collection: 63% of samples were taken at the laboratory's blood drawing room, while 37% came from the various hospital departments. Time of the realization of the samples was not mentioned on the cards or on the labels of the tubes. The anticoagulant used for all samples was sodium citrate at a concentration of 3.8%. The filling of the tubes was noncompliant in 22.25%. Registration and triage of the tubes systems were manual. Centrifugation was carried out at a rotation speed of 5000 G for 5 minutes and at a temperature set at 22°C. Hemolyzed samples accounted for 3% of the tubes.

“…Though most studies in the literature have not mentioned the exact figures regarding the prevalence of the various variables/errors, they have suggested that 0.01-0.5% of all test results are erroneous due to pre-analytical variables. 2,12 An Indian study 13 identified 1% preanalytical errors in a haematology laboratory. This study evaluated 135,808 samples out of which they identified presence of pre-analytical errors in 1339 samples, a rate of 1%.…”
