Principles of Laboratory Analysis in Perfusion Tech-II

This flashcard set covers key terms and concepts related to laboratory tests, their purpose, predictive values, role in patient care, and specific analyses relevant to perfusion technology.

Laboratory Testing

The procedures performed to examine biological samples to provide information on a patient's health.

Predictive Value

The proportion of positive or negative test results that are correctly identified, linked to the prevalence of the disease.

Sensitivity

The probability of obtaining a positive test result when the disease is present.

Specificity

The probability of obtaining a negative result when the disease is absent.

False Positive

A test result that indicates a person has a disease when they do not.

False Negative

A test result that indicates a person does not have a disease when they do.

Quality Control

Processes and measures to ensure the reliability and accuracy of laboratory test results.

Analytes

Substances or compounds measured in clinical laboratory tests.

Mass Screening

Testing of a large population to identify individuals with potential diseases.

Therapeutic Monitoring

The regular assessment of drug levels in a patient to optimize the effectiveness and safety of their treatment.

Interferences

Factors causing deviations in test results, such as medications or biological variations.

Renal Function Tests

Tests that assess kidney function, including blood urea nitrogen (BUN) and creatinine.

Electrolyte Panel

A blood test measuring the levels of key electrolytes necessary for normal body function.

Blood Gas Analysis

A test measuring the amount of oxygen and carbon dioxide in blood and evaluates pH.

Hemostasis

The process that prevents and stops bleeding, involving vascular reaction and platelet plug formation.

ECMO

Extracorporeal Membrane Oxygenation; a procedure that provides cardiac and respiratory support.

Hyperthermia in Chemotherapy

The use of elevated body temperature to enhance the effectiveness of chemical agents against cancer.

Intraperitoneal Chemotherapy

Delivery of chemotherapy directly into the abdominal cavity to treat localized cancer.

Quality Assurance

Activities designed to ensure that processes are conducted correctly and consistently to achieve reliable results.

Biochemical Markers

Substances used as indicators of a biological state, particularly for disease diagnosis.

Sample Collection

The process of obtaining specimens from patients for laboratory testing.

Analytic Variables

Variables pertaining to the methods and instruments used to generate test results.

Post-Analytic Factors

The interpretation and reporting phases of laboratory tests where results are communicated.

Workflow

The sequence of processes through which work passes from initiation to completion.
