Clinical testing in the test error of 60% -70% from the analysis of the stage of quality control failure.
Clinical medical testing as an indispensable part of modern medical treatment, the use of advanced equipment combined with scientific testing methods to analyze the patient's blood and body fluids, so that the patient's condition is reasonable judgment to improve the effectiveness of clinical treatment.
The indicators commonly used in clinical medical tests have multiple clinical values for diagnosing diseases, determining therapeutic effects, guiding treatment and evaluating prognosis. With the improvement of blood biochemical testing technology, the sensitivity, accuracy and specificity of the test have been significantly improved, and the quality control of clinical medical testing as a key link to improve the accuracy of the test.
Most of the errors in medical testing work are concentrated in the pre-test, test, test in the three links, so the staff want to better control the detection of errors, the key is to start from the three links, strict control, only then, to the greatest extent possible to avoid the occurrence of errors, for the doctor's clinical diagnosis to provide a more accurate and scientific basis.
Error is divided into: 1, systematic error in the staff operation of the detection instrument in the process, the patient's sensory impairment and instrumentation due to the lack of calibration and bias will lead to the occurrence of detection error, so that the detection value deviates from the true value, such errors can be eliminated through technical means, but also through scientific and reasonable rules and regulations to be avoided. 2, random error is also known as random error. Accidental error, refers to the remaining part of the error in addition to the systematic error. Random error will be affected by a variety of factors, but its observed value will not appear systematic or directional changes, changes in the randomness is extremely strong.
Methods to reduce pre-analytical error: we believe that to ensure that the delivery of specimens that can truly reflect the condition, meet the analytical requirements, and refuse to accept unqualified specimens is the key to improve the quality of pre-analytical clinical testing. Testing personnel should strengthen communication with clinical staff, close cooperation, and do a good job of rejecting unqualified specimens, reduce the experimental error in clinical testing before analysis, reduce unnecessary waste and the occurrence of medical disputes. Only to ensure high-quality specimens, only high-quality test results, in order to provide accurate experimental results for clinical diagnosis, treatment and observation.
