Background: Clinical laboratories usually focus their attention on quality control methods and quality assessment programs in dealing with the analytical aspects of testing. However, quality in clinical laboratories cannot be assumed by merely focusing on analytical aspects only. Preanalytical processes are equally important for ensuring quality services since most of the laboratory errors occur in this phase thus influencing patient outcomes and cost. Objective: The aim of this study was to evaluate and compare the level of completion of request forms in blood bank (BB) and biochemistry (BC) laboratory of a teaching hospital in North India. Materials and Methods: A total of 3532 requisitions were received in BB and 18,410 in BC laboratory between November 2014 and April 2015. The information regarding incomplete/inappropriate requisitions and samples in both departments were recorded, compared, and analyzed. Results: The most common deficiency was the absence of clinical/provisional diagnosis among both the outpatient department (OPD) (50.7%) and inpatient department (IPD) (3.2%) request forms in BC. Doctor's name not mentioned in 1.1% of the OPD requisitions and platelet count not mentioned on 7.8% of platelet request forms in IPD requisitions were the most common deficiencies in BB. The only well-documented parameter was the patient's name. Maximum numbers of incomplete requests were received from medicine OPD's followed by Intensive Care Units, emergency and medicine wards. Conclusions: As laboratory data play a significant role in medical diagnosis, incorrect/incomplete data provided to the laboratory significantly affects the comments and successful outcome of the treatment that patient receives. Therefore, clinicians and paramedical staff should be trained to adequately fill all the required information into the request forms and appreciate its importance to patient's management. Furthermore, feedback/interpretation of significant results by the laboratory physicians to the clinicians should be emphasized.
