Preanalytical errors in blood gas testing Preanalytical errors in blood gas testing. J Presented by Ana-Maria Simundic, PhD, Prof. of Medical Biochemistry, Zagreb University, Croatia. Playback. Slides. About this webinar. This app focuses on the preanalytical phase of blood gas testing and what operators can do to avoid errors. The recommendations are based on existing literature and international best practices. Examples are constructed, unless specific reference is given, with the purpose of illustrating the consequence of preanalytical errors.4/5(86).
It is important to understand the physiological principles underpinning blood gas analysis, so these will be outlined briefly before exploring some practice issues for patients undergoing arterial blood gas sampling. The key to making sense of arterial blood gases is to use a structured approach. Some patient case studies show this in action. In whole blood testing, as practiced in blood gases analysis, there are numerous sources of preanalytical error, some of which are: air contamination, post draw metabolism, abnormal cell count, liquid heparin dilution, venous admixture, specimen mixing .

The objective of this article is, therefore, to provide checklists with the preanalytical and preparatory considerations when performing method comparisons on blood gas analyzers. The typical parameters found on a blood gas analyzer are: Blood gases and pH: pH, p O 2, and p CO 2 Electrolytes: c Na +, c K +, c Ca 2+.

Patient preparation is an additional preanalytical consideration that is highly susceptible to the introduction of errors. Fortunately, patient adherence to preparation instruction and the implementation of specific reference ranges can reduce the impact of some physiological variables on test results.

Blood Gas Analysis (BGA) is almost a routine test in patients admitted in ICCU/ICU. Recently, I happened to visit a relative admitted in ICCU of a medical institute and there, I found the consultant doctors discussing the accuracy of BGA report. Their conclusion was that most of the times the results were not by: 1.
A type of line commonly used to monitor blood pressure and collect blood gas specimens is: An A-line. A subcutaneous vascular access device consisting of a small chamber attached to an indwelling line that is implanted under the skin and located by palpating the skin is.
