Sample records for pre-analytical sample processing
What is the phase of the testing process that occurs prior to the actual analysis of the specimen known as?The pre-analytical phase consists of all steps from preparing the patient for collection of the specimen to processing of the specimen prior to the analytical step. Pre-analytical errors can occur in vivo or in vitro.
What is the prePreanalytical phase comprises of test selection, patient identification, collection of the sample, handling of the sample, sorting out, pipetting and centrifugation (2, 3). Negligence in any of these steps can lead to erroneous results attributed to preanalytical phase.
What could be an undesired effect of a patient Overhydration consuming large volumes of water or other fluids prior to or during sample collection?When overhydration occurs quickly, vomiting and trouble with balance develop. If overhydration worsens, confusion, seizures, or coma may develop.
Why is preThe preanalytic phase is an important component of total laboratory quality. A wide range of variables that affect the result for a patient from whom a specimen of blood or body fluid has been collected, including the procedure for collection, handling, and processing before analysis, constitute the preanalytic phase.
