In vitro hemolysis depends mainly on the way in which the blood samples are drawn and treated, and it may in particular depend on the blood being forced through too fine a needle (4) or through the large-bore needle of a syringe into a tube; it may also be caused by shaking the tube too vigorously and/or centrifuging blood specimens before clotting is complete. Collection technique is most often the cause of hemolysis. Baek S-W, Lee M-W, Ryu H-W, Lee K-S, Song I-C, Lee H-J, et al. 8600 Rockville Pike They provide quantitative measurement with high repeatability, thereby standardizing the identification process of hemolyzed specimens.

Factors Affecting the Risk of Blood Bank Specimen Hemolysis Some suggestions that may help you to manage anemia include: Hemolytic anemia happens when something is destroying your red blood cells. Further investigations in combination with clinical history, physical examination, and peripheral blood smear are essential for the differentiation of in vivo or in vitro hemolysis.12,18, In vitro hemolysis is a result of pre-analytical causes associated with sample collection, jarring transportation methods, extreme temperature, sample handling, delayed processing, and prolonged storage.19-21 Hemolysis resulting from phlebotomy may be caused by incorrect needle size, improper tube mixing, incorrect filling of tubes, excessive suction, prolonged tourniquet, and difficult collection. This condition may be a sign you have an inherited medical condition or a medical issue caused by infection. The addition of a brief comment to the laboratory report with very little evidence-based data support cast doubts on the interpretation of test results and its benefit to patient care.1,52,53 The final option in managing hemolyzed samples would be to perform the analysis, but the final result is then mathematically adjusted based on the estimated degree of sample hemolysis.54 Correcting and reporting results may be essential in making a primary diagnosis, but it should be performed after intravascular hemolysis has been ruled out. Moreover, hemolysis produces spectrophotometric interference with other laboratory methods. PDF The Breakdown on Hemolyzed Specimens - NCDHHS The most prevalent pre-analytical interference and a major source of error producing unreliable laboratory test results is hemolysis of blood samples.

Reasons accounted include unease of increased specimen rejection rate, lack of standardize units of measure, differences in instrument-specific cutoff, negative impact on throughput, poor harmonization of analytical techniques, organization and laboratory economics, and lack of a reliable quality control systems. Sometimes, problems related to a cells structure or components shorten its lifespan. Excessive hemolysis can lead to hemolytic anemia. If tests are performed within 48 hours of collection, transfer serum to a sample tube (cryovial) and store at 4C. Hemolysis (either in vivo or in vitro) is traditionally detected by visual inspection of the specimen after centrifugation and comparing it with the hemolytic chart, which shows the color of samples with increasing concentrations of free hemoglobin.42-44 Visual inspection is time-consuming, thus, causing a delay in reporting.1,45 Visual detection of hemolysis may also vary from one person to the other and may lead to inaccuracy in estimating the actual prevalence of hemolyzed serum samples (i.e., experienced technologists are incapable to exactly rank the various concentration of hemolysis in serum).42,43 In neonatal samples where elevated bilirubin concentration is common, the ability to detect hemolysis by visual inspection may further be impaired causing gross underestimation of hemolysis.2 Visual assessment is highly inaccurate and almost impossible to standardized, enabling only gross classification of hemolysis.40,43 Currently, chemistry analyzers are capable of performing automated assessments of serum indices including hemolysis index (HI).

Many of these concerns, however, have been addressed and evidence now supports automated HI in enlightening quality and patient safety.47 Since there is no consensus on how to help clinicians distinguish between the two hemolysis types (in vivo and in vitro), clinical surveillance is essential. We evaluated the causes of hemolysis in samples received by our STAT section in the Department of Laboratory Medicine of the University Hospital of Padova, which performs all clinical chemistry tests on specimens collected using lithium heparin as anticoagulant (Becton Dickinson). It is advisable for a person to consult a doctor if they experience any of the following symptoms: Hemolysis is a natural process where the body destroys older RBCs that no longer work efficiently. The cause of hemolysis can be extrinsic, coming from an outside source, or intrinsic, which is when it comes from the RBC itself. Unless you're using a device like.

Studies on in vitro hemolysis and utility of corrective formulas for reporting results on hemolyzed specimens. Practices for identifying and rejecting hemolyzed specimens are highly variable in clinical laboratories. Hematocrit is the percentage of a person's blood volume that is red blood cells. An elevation of LDH activity is typical of intravascular hemolysis.40,41 Yet, because of low diagnostic sensitivity and specificity, a change in the LDH isoenzyme pattern seems less appropriate for the identification of in vivo hemolysis.31. official website and that any information you provide is encrypted Complications due to hemolytic anemia can include: Arrhythmia, cardiomyopathy, heart failure, and iron deficiency are other possible complications. People may develop hemolytic anemia due to genetic conditions that cause anemia. In the laboratory, HI report generated automatically through laboratory information system can save human resources and reduces turnaround time.50 However, the system must be able to over-ride the suppression of potassium results in cautiously taken but persistently hemolyzed repeat samples and alert clinicians to the likelihood of in vivo hemolysis in such cases.28. A doctor may measure a persons hematocrit levels. Validation of hemolysis index thresholds optimizes detection of clinically significant hemolysis. If no errors in these procedures were identified and in vivo hemolysis was not suspected clinically, serum haptoglobin was measured immediately and at 24 h with a view to confirming the presence of any acute hemolysis, which was clinically evaluated and then confirmed in a further phase.
