24 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Analytical range
- The concentration interval over which a method has demonstrated the performance required for its specified use.
- Matrix effect
- Influence of specimen components on an assay response that can differ from behavior in calibration material.
- Calculated estimate
- A value derived using a formula and assumptions rather than directly measuring the physiological quantity of interest.
- Critical result
- A result requiring the institution’s urgent communication and assessment pathway because of its potential clinical significance.
- Mean cell volume
- The average red-cell volume calculated or measured within the analyzer method and interpreted with specimen quality.
- Mixing study
- An assay comparison using patient and normal plasma to investigate a prolonged clotting result under specified conditions.
- Reticulocyte
- An immature red cell containing residual RNA that can help assess marrow response in the appropriate context.
- D-dimer
- A degradation marker associated with cross-linked fibrin breakdown that is not specific for one clinical cause.
- Selective medium
- A culture formulation that inhibits some organisms to favor recovery of others under the specified conditions.
- Differential medium
- A culture formulation that displays a reaction useful in distinguishing organisms that grow in the medium.
- Presumptive identification
- An organism assignment supported by preliminary features that may require additional validated confirmation before final reporting.
- Susceptibility breakpoint
- An interpretation boundary defined for a specified organism, drug, method and clinical framework rather than all organisms.
- Trophozoite
- An active organism stage whose morphology and movement can support identification when the specimen and method preserve them.
- Concentration method
- A preparation process intended to improve recovery of selected parasite stages while retaining method-specific limitations.
- Kinetoplast
- A distinct mitochondrial DNA-containing structure relevant to recognizing particular flagellate stages in an appropriate microscopic preparation.
- Detection limit
- The method-dependent ability to recognize a target under specified conditions, not a guarantee that every negative specimen is uninfected.
- Direct antiglobulin test
- A test detecting immunoglobulin or complement associated with red cells in the patient specimen, requiring contextual interpretation.
- Reverse ABO typing
- Testing patient serum or plasma against suitable known reagent red cells to assess the expected ABO antibody pattern.
- Prozone
- An antibody-excess condition that can disrupt expected lattice formation and produce misleading results in suitable assay formats.
- Compatibility testing
- A coordinated set of specimen, antibody and component assessments within the responsible transfusion service and actual policy.
- Internal quality control
- Monitoring intended to detect analytical-system instability during routine work using appropriate materials, limits and investigation rules.
- External quality assessment
- An organized comparison of laboratory performance with suitable external evaluation rather than a complete guarantee for all patient samples.
- Traceability
- The ability to link a specimen and result with relevant collection, method, reagent, equipment, operator and record information.
- Corrective action
- A documented response addressing the cause of a nonconformance and assessing whether the intervention prevented recurrence.
