Increased turbidity of the specimen may interfere with the measurement of hemoglobin and result in a falsely increased hemoglobin result. Lipemia, leukocytosis, paraproteinemia, cryoglobulinemia, cryofibrinogenemia, and presence of abnormal hemoglobin are all possible causes.
The specimen should not be delayed for more than two hours prior to centrifugation because some of the analyte levels (such as glucose, ionized calcium, bicarbonate, folate, etc.) may be falsely decreased due to cellular consumption…
Or falsely increased (such as potassium, ALT, AST, creatinine, etc.) because of the excessive release.
Random Access analyzers have the capability of testing specimens out of sequence.
This is an important function when it comes to STAT specimens being placed on the analyzer after several routine samples have been previously placed in the same analyzer.

- Parallel refers to all specimens analyzed at the same time.
- Multi-channel refers to each specimen that may be subjected to multiple analyses.
- Multi-channel refers to each specimen that may be subjected to multiple analyses.
A urine drug screen for pre-employment is a test that requires chain-of-custody procedure and they are forensic specimens.
Chain-of-custody procedure requires detailed documentation tracking the specimen from the moment of collection to the moment the results are reported.
Chain-of-custody procedure requires detailed documentation tracking the specimen from the moment of collection to the moment the results are reported.
Ideally, 20 separate runs of testing should be performed prior to starting a new lot of control material in order to establish its mean and standard deviation.
Regarding hospital’s pneumatic tube system, The vibrations and shock to the blood specimen created during pneumatic tube transportation can damage the red blood cells and negatively affect some test results.
CLSI recommends that potassium, plasma hemoglobin, acid phosphatase, and lactate dehydrogenase not be transported to the laboratory via pneumatic tube system.
A test with high specificity accurately detects the absence of disease. The more specific a test is, the fewer false-positive results will occur.
A test with high sensitivity accurately identifies the presence of disease. The more sensitive a test, the fewer false-negative results it produces.
The Renal Function Panel consists of Glucose, BUN, Creatinine, Sodium, Potassium, Chloride, CO2, Calcium, Albumin, Phosphorus.
The Hepatic Function Panel A consists of AST, ALT, Alkaline Phosphatase, Total Protein, Albumin, Total Bilirubin, Direct Bilirubin.
The Lipid Panel consists of Cholesterol, Lipoprotein, HDL, Triglycerides.
The Electrolyte Panel consists of potassium, sodium, chloride, carbon dioxide.
The Electrolyte Panel consists of potassium, sodium, chloride, carbon dioxide.
According to the National Fire Prevention Association (NFPA), class A fire involve ordinary combustibles, class B fires involve flammable liquids and gases, fires of electricity or electrically charged equipment are class C fires and class D fires involve flammable Metals.
Random error is an error that occurs solely by chance. In the 2 SD limit, random error accounts for 5% of the QC results outside of the limit.
Systematic error affects all samples, may produce a "bias" in the method and it is related to the accuracy of it.
TD, or To Deliver, pipettes are calibrated to deliver the correct amount of solution without "blowing out" the amount left in the pipette's tip.
Pipettes labeled TC, or To Contain, are calibrated to include the amount left in the pipette's tip. Therefore, "blowing out" the final drop of solution is required.
Value stream mapping is a Lean process that can be used by laboratory personnel to document and analyze all of the steps that bring a laboratory test result (product or service) to the customer.
Root cause analysis is a method that is used to determine what caused a quality or performance problem for the purpose of correcting the primary cause of the problem.
5S is a Lean quality improvement method that, if followed, will create a safe and efficient work environment.
FMEA (Failure mode and effects analysis) is used primarily to evaluate a process. This tool is used to analyze risk and highlight aspects of a process that should be targeted for improvement.
VOC (Voice of customers) is a tool that can be used to understand what the customers want from the customers' perspective. It is used to identify key drivers of customer satisfaction.
A quality control plan (QCP) is a written document describing the practices and procedures performed by your laboratory to reduce the chance of possible failures and errors in test processes.
The SIPOC diagram is used in Six Sigma to help identify the key elements in a process: supplier, inputs, outputs, and customer. This is a high-level map that encourages system thinking by focusing the team to see the process through the customer's eyes.
- A trend is any progressive drift of values to one side of the average value for at least three days.
- A shift is an abrupt change from the established average value.
- A shift is an abrupt change from the established average value.
Foul-smelling chemicals should never be disposed of down the drain and some chemicals can react with the metals in the pipes.
Standard precautions means that all specimens must be handled as if they are hazardous and infectious according to the CDC.
Improper balance of the centrifuge can result in potential tube breakage, exposure to biohazardous agents, and mechanical centrifuge damage.
POCT offers many advantages including its ability to be portable and testing at the patient bedside, ease of use, and the features available on analyzers such as QC lockout.
The drawback to point -of-care testing (POCT) is the decreased precision in POCT data. POCT testing is not well suited for monitoring therapy or patient status in instances where small changes are important.
