However, laboratory results do not always correspond with the patient's .

It may have negative effects on patient care, by contributing to inappropriate treatment, an increase in lengths of hospital stay, and dissatisfaction with healthcare .

There are pre-analytical, analytical and post analytical factors that contribute to accurate test results in clinical laboratories. Pre-analytical variables account for 32-75% of . A myriad of patient-related factors such as age, gender, dietary intake, and exercise can significantly impact clinical laboratory test results. These factors can be .

In this section.Factors Affecting Quality of Laboratory Result During Ordering, Handling, and Testing of the Patient’s Specimen at Hawassa University College of Medicine and Health Science Comprehensive .

Factors affecting lab test results There are a few reasons why a test result could fall outside of the established reference range despite the fact that you are in good health. Generally, these factors only come into play when the test value is slightly higher or lower than the reference range.

A myriad of patient-related factors such as age, gender, dietary intake, and exercise can significantly impact clinical laboratory test results. These factors can be classified into two categories: non-modifiable patient-related factors (e.g., age) and modifiable patient-related factors (gender [to an extent], dietary intake, and exercise). This article explains what we know so far about both nucleic acid tests and antibody detection tests for the SARS-CoV-2 virus, and what factors can affect the reliability of an individual test result. As with all lab tests, a number of factors determine the accuracy of a COVID-19 test result.

In clinical laboratory activities, quality test result plays a significant role on medical diagnosis, decision, monitoring prognosis of disease with or without treatment. Studies indicated that up to 80% of medical decisions rely on laboratory test results . Thus, timely delivering of laboratory results is the crucial mainstays of a competent .

Upon completion of this activity, participants should be able to: List the pre-analytical variables commonly encountered in laboratory medicine. Identify the nature and frequency of pre-analytical factors responsible for sample rejection. Describe effective strategies to reduce the rate of specimen rejection and mitigate the risk of patient harm.

Many physiologic factors can affect a total hemoglobin concentration value. The source of the blood sample, patient body position at the time of the blood draw, and the use of a tourniquet to retrieve the blood sample can influence the laboratory value. The site of the body at which the sample is taken can also affect results.factors affecting laboratory test resultsIn general, moderate or excessive exercise has an effect on laboratory test results, but it is up to the physician to interpret the effects. Exercise also has some effects on hemostasis. . Timing factors can affect test results. In some cases, such as testing drug levels, the timing of the collection must coincide with the time the dosage was . Some food shows a short-lasting effect whereas others have a long-term effect. Variation in laboratory results is likely if the test is performed with and without taking such food, especially those with short-lasting effects, at different instances. 7. Moderate to strenuous exercise has direct effects on the concentration of analytes like . As determined by laboratories, the turnaround time (TAT) of an IVD test is largely influenced by the time difference between when specimens are received in the laboratory and the time results .Other factors which can affect laboratory results are time of day or a specific phase of a person’s menstrual cycle. The following tables show some examples where multiple reference ranges are used for a particular test. . In some cases, lab test results may be reported with a warning of a critical value to help alert health care staff of .Pre-analytical variation includes all the steps that occur from test ordering until right before sample analysis. While the likelihood of variation in any of the three phases is not negligible, the vast majority of laboratory variation emerges from the many factors affecting laboratory specimens prior to testing.The following factors can affect the results obtained from samples and should be taken into consideration when interpreting results. Collection-to-Test Time. Delay between the collection of a sample and the testing of the sample can affect the results obtained, particularly if not stored at the appropriate temperature (see below).Authors. Reproducibility is the ability of an assay to provide consistent results (when testing the same samples) in different laboratories. The validation of a new diagnostic assay should include specific assessment of assay reproducibility to determine the degree to which results are unaffected by minor changes in experimental conditions. Therefore, this study was aimed to determine factors affecting the quality of laboratory test results during ordering, handling, and testing patient specimens in Hawassa University College of Medicine and Health Science Comprehensive Specialized Hospital from October, 2018-may, 2019.Problem Causes Affected analyte Delay in processing Overnight storage >6 hour delay in separation Increased potassium, phosphate, LDH, AST. Incorrect storage Storing unseparated sample in the fridge Increased phosphate and potassium Decreased bicarbonate Haemolysis Expelling blood through needle Vigorous shaking Extreme .
