Study Notes
Laboratory Testing Overview
- Laboratory tests deliver critical information for physicians to diagnose and manage patient conditions.
- Provides quantitative data to assess various body functions and health status.
Uses of Laboratory Tests
- Aids in diagnosing pathologic conditions.
- Monitors patient progress and guides treatment decisions.
- Establishes baseline health metrics for patients.
- Helps prevent or mitigate disease severity.
- Complies with legal health requirements.
Routine Testing Purpose
- Aims to detect diseases early, improving treatment outcomes.
CLIA Regulations
- CLIA (Clinical Laboratory Improvement Amendments) enhances the quality of laboratory testing in the U.S.
Specimen Storage Requirements
- Refrigerators for specimens must maintain a temperature between 36°F and 46°F.
- Temperature checks required daily, with records maintained.
- No food is to be stored in specimen refrigerators, and they must feature warning labels.
Emergency Procedures
- Emergency eyewash stations flush eyes after exposure to harmful substances to prevent permanent damage.
Temperature for Testing
- Ideal room temperature for tests is between 59°F and 86°F.
Laboratory Directory Content
- Contains test names, CPT codes, reference ranges, specimen requirements, techniques, handling instructions, and rejection causes.
Laboratory Request Forms
- Essential for accurate testing, reporting, and billing, including key patient information like age, gender, and clinical diagnosis.
Reporting Results
- STAT requests prompt rapid reporting via telephone or fax.
Common Test Profiles
- Comprehensive Metabolic Profile includes a range of tests (e.g., albumin, bilirubin).
- Hepatic Function Profile and Prenatal Profile encompass specific tests for liver function and maternal health, respectively.
Laboratory Report Essentials
- Reports must feature laboratory details, patient information, testing dates, and results against reference ranges.
Comparative Analysis
- Results from external labs must be compared against local reference ranges to account for variability in testing methods.
Patient Preparation for Tests
- Some tests necessitate patient preparation to ensure specimen quality and accurate results.
- Ensuring that patients understand the need for preparation improves compliance.
Specimen Definition and Examples
- A specimen is a sample representing a larger whole.
- Examples include blood, urine, tissue biopsies, and various body fluids.
Laboratory Handling Instructions
- Manufacturer instructions should guide the transport and testing of specimens, ensuring accurate collection and handling.
Importance of Proper Identification
- Unique identifiers, such as patient name and date of birth, are critical to avoid mix-ups.
Quality Control in Testing
- Quality control ensures reliability of test results through both internal (built-in) and external (separate checks) systems.
Invalid Test Results
- Error sources include improper specimen handling or outdated reagents.
Test Result Types
- Qualitative results indicate presence/absence, while quantitative results specify exact amounts of substances.
Safety Guidelines in the Laboratory
- Organize glassware to prevent breakage.
- Properly label and handle reagents.
- Dispose of contaminated materials appropriately.
- Maintain hand hygiene and enact measures to prevent spills.
