Without precisely following the correct procedures in sample reception, the quality of results is not assured,. Research statistics has shown that most laboratory errors take place in the pre- analytical stage, of which sample reception is a central part. It is therefore crucial that all the procedures are followed meticulously. Departments of A Medical Laboratory 4 Haematology Biochemistry Immunology & serology Microbiology Urine, Stools, Blood, Body fluids Pathology Genetics  Lab Request Form 5 Information should include: Patient name and ID (Double Identification) Age Gender Hospital Room & Department Date and time of collection Sample type and site Person who collected the sample A list of the tests that need to be performed Provisional diagnosis Referred Physician Samples that arrive at a laboratory without clear labelling are generally rejected. Sample Rejection 6 Incomplete request form Ambiguous Identification Unlabeled, Wrongly labeled samples Mis-matched samples Improper container Improper temperature Leaking container Insufficient quantity Dried sample Prolonged transport time  Registry & Labeling 7 These follow receiving and accepting the sample. A patient register can be maintained either on paper or electronically. There are many Laboratory Information System (LIS) software packages. Sample labeling: when the sample is introduced in the register the sample is labeled. This creates the traceability: sample portions are made traceable to the primary sample by using the same label on all the portions. This in turn ensures that all the sample information is properly recorded.  8 Samples are then introduced to the specialty area or bench according to the type of sample and required tests for further testing. Urine Stools CSF and biological fluids Pus and wounds Blood culture Sample Processing 9 Without precisely following the correct procedures in the sample processing stage, the quality of results is not assured, and the health of both patient and staff members is risked. Sample reception is a central part in the pre-analytical stage. It is therefore crucial that all the procedures are followed meticulously, and that all the controls are performed thoroughly and at all times.  10 Sample processing: Review of requests by authorized personnel. Procedure for processing urgent samples. Procedure for dealing with verbal requests (ensuring that all the relevant information is collected by filling-out a Request Form by the laboratory based on the verbal request). Procedure for sample rejection. 11 12 13 Culture 14 15 Blood Culture Machines 16
