OBJECTIVES:To study different types of pre-analytical errors in clinical biochemistry lab and how to minimize them. METHODOLOGY: An observational study was done at Department of Biochemistry , Osmania General Hospital for a period of 2 months from Aug 2020-Sep 2020.During this phase different types of errors were monitored. RESULTS: During a period of 2 months ,10000 samples were analyzed and among them 400 were found to be having an error. i.e. 4%. Among them Hemolyzed samples (37.5%), Lipemic samples(25%), Misidentification of samples(15%), Insufficient volume(12.5%) and Sample mixing (10%). CONCLUSION: Proper training to nursing staff and phlebotomist regarding use of vacutainer needles instead of syringes and time of collection of samples reduces the error of hemolysis and lipemia.Use of Barcode labels reduces the error of misidentification. Proper education regarding volume of blood to be collected and use of correct vacutainers reduces the error of insufficient volume and sample mixing.

Analytical Errors

To categorize and calculate the percentage error of pre-analytical variables in the clinical biochemistry laboratory. Prospective observational study conducted for two months with documenting the frequency and type of pre-analytical errors occurring in venous samples. The total errors recorded were 1.31%. Insufficient volume followed by haemolysis amounted to a major proportion of errors. Continuous pre-analytical phase evaluation and taking corrective measures to make this phase error-free, have to be done.

Background: This study was carried out to identify the causes of pre-analytical errors in the clinical biochemistry laboratory and their percentage occurrence so as to formulate the strategy for necessary corrective and preventive actions. Methods: A retrospective quantitative study was conducted in the department of biochemistry to identify the different causes of pre-analytical errors in the outpatient and inpatient samples. The sample rejection register and test requisition forms for the period of May 2018 to April 2019 were analysed and the percentage occurrence of the different types of errors was calculated. Results: Data analysis revealed that the occurrence of different errors was as follows: hemolysis (46.43%), sample not received (28.32%), insufficient quantity (8.16%), improper collection technique (7.14%), delayed transport (5.87%), wrong container (1.79%), sample clotted (1.28%), lipemic sample (0.77%) and sample exchanged during separation in lab (0.26%). Conclusion: The decline in the errors during the analytical phase of sample processing has shifted the focus towards reducing errors occurring in the pre-analytical phase. This is necessary to ensure patient safety. Keywords: Pre-analytical errors, Biochemistry, hemolysis.

Extensive Damage

Most of the approximately 75 known eggs of the extinct great auk ( Pinguinus impennis) are in public museums, with a few in private collections. A small number of these eggs has sustained damage, either at the time of collection or subsequently, and two of these eggs are known to have been repaired. The two eggs suffered rather different types of damage and were subsequently restored using different techniques. The first, known as Bourman Labrey's egg, sustained extensive damage sometime prior to the 1840s, when the shell was broken into numerous pieces. This egg was repaired by William Yarrell in the 1840s, and when it was restored again in 2018, it was discovered that Yarrell's restoration had involved the use of an elaborate cardboard armature. This egg is currently in a private collection. The second egg, known as the Scarborough egg, bequeathed to the Scarborough Museum in 1877, was damaged (by unknown causes) and repaired, probably by the then curator at Scarborough, W. J. Clarke, in 1906. This egg was damaged when one or more pieces were broken adjacent to the blowhole at the narrow end (where there was some pre-existing damage). The media reports at the time exaggerated the extent of the damage, suggesting that the egg was broken almost in two. Possible reasons for this exaggeration are discussed. Recent examination using a black light and ultraviolet (UV) revealed that the eggshell had once borne the words, “a Penguin's Egg”, that were subsequently removed by scraping.

Aims and methodAlthough alcohol is reported as commonly associated with self-harm, there is nothing in the literature that bases the association on validated screening tools. We sought to discern the different types of alcohol use as discriminated by the Alcohol Use Disorders Identification Test (AUDIT). Completed AUDITs from a 2-year period were analysed, all relating to people who had presented to a district general hospital in Northumberland following self-harm.ResultsThe proportion of dependent, harmful and hazardous drinkers identified using AUDIT was many times higher than previously estimated in similar studies that had not used a validated alcohol screening tool.Clinical implicationsThe routine use of an alcohol screening tool should be part of any standard psychosocial assessment of self-harm, to guide appropriate interventions for problematic alcohol use that might otherwise be overlooked.
