Lab Test Course

Lesson 1 • Specimen Handling and Chain of Custody

Details proper collection, labeling, transport, and storage of specimens. Correct handling prevents pre-analytical errors that compromise test validity.

Lesson 2 • Lab Equipment and Instrumentation Basics

Introduces common instruments, their functions, and routine maintenance checks. Students gain confidence operating equipment before performing actual tests.

Lesson 3 • Understanding Test Requisitions and Reports

Explains how to read test orders, result reports, and reference ranges. Students connect ordering information to result interpretation from the start.

Lesson 4 • Introduction to Diagnostic Testing

Covers the role of lab tests in clinical decision-making and patient care pathways. Anchors all subsequent technical content in real-world diagnostic purpose.

Lesson 1 • Principles of Quality Control

Defines quality control concepts including accuracy, precision, and bias. These principles underpin every analytical decision made in subsequent chapters.

Lesson 2 • Analytical and Post-Analytical Quality

Addresses in-run quality checks and result verification before reporting. Students learn to close the QA loop from analysis through final result delivery.

Lesson 3 • Standard Operating Procedures

Covers how to write, follow, and update SOPs for lab processes. Consistent SOP use is the primary mechanism for reducing procedural variability.

Lesson 4 • Proficiency Testing and Accreditation

Explains external proficiency testing programs and accreditation requirements. Students understand how labs demonstrate competency to oversight bodies.

Lesson 1 • Anemia Classification and Workup

Applies CBC and morphology data to classify anemias by mechanism and cell size. Students build a systematic workup approach used in clinical practice.

Lesson 2 • Hematology Instrument Maintenance

Details daily startup, calibration, and troubleshooting for hematology analyzers. Instrument reliability directly affects the accuracy of all CBC results.

Lesson 3 • Coagulation Testing Fundamentals

Introduces the coagulation cascade and key clotting tests including PT and aPTT. Results are linked to clinical conditions such as bleeding disorders and anticoagulation monitoring.

Lesson 4 • Blood Cell Morphology and Identification

Teaches recognition of normal and abnormal red cells, white cells, and platelets on smears. Morphology skills are foundational to all hematology interpretation.

Lesson 1 • Principles of Photometric Analysis

Explains absorbance, transmittance, and Beer-Lambert law as applied to chemistry analyzers. These optical principles underlie most quantitative chemistry assays.

Lesson 2 • Metabolic Panel Interpretation

Covers glucose, BUN, creatinine, and electrolyte testing with clinical correlation. Students link panel abnormalities to renal, hepatic, and metabolic conditions.

Lesson 3 • Lipid Panel and Cardiac Markers

Addresses lipid fractionation, cardiovascular risk markers, and troponin assays. Students apply results to cardiovascular risk stratification and acute event detection.

Lesson 4 • Liver Function and Enzyme Testing

Teaches hepatic enzyme panels, bilirubin fractionation, and protein markers. Enzyme patterns help distinguish hepatocellular from cholestatic liver disease.

Lesson 1 • Antimicrobial Susceptibility Testing

Explains disk diffusion, broth microdilution, and MIC interpretation for antibiotic selection. Results guide clinicians in choosing effective therapy.

Lesson 2 • Bacterial Identification Methods

Teaches Gram staining, colony morphology, and biochemical identification of bacteria. Students progress from visual observation to definitive organism identification.

Lesson 3 • Fungal and Parasitic Testing

Introduces culture, staining, and microscopic methods for fungi and parasites. Students identify clinically significant organisms from common specimen types.

Lesson 4 • Molecular Diagnostics for Pathogens

Covers PCR-based pathogen detection, multiplex panels, and result interpretation. Molecular methods offer speed and sensitivity beyond traditional culture.

Lesson 1 • Infectious Disease Serology

Covers antibody testing for viral and bacterial infections including IgM versus IgG interpretation. Students apply serological windows and seroconversion concepts to clinical scenarios.

Lesson 2 • Autoimmune and Rheumatology Markers

Teaches ANA, anti-dsDNA, rheumatoid factor, and complement testing for autoimmune workup. Students recognize patterns that differentiate autoimmune conditions.

Lesson 3 • Blood Bank and Transfusion Serology

Introduces ABO and Rh typing, antibody screening, and crossmatch procedures. Transfusion serology errors carry direct patient safety consequences.

Lesson 4 • Immunoassay Troubleshooting and Interference

Addresses hook effect, heterophile antibodies, and matrix interference in immunoassays. Students apply systematic troubleshooting to resolve discrepant results.

Lesson 1 • Urine Microscopy and Sediment Analysis

Teaches identification of cells, casts, crystals, and organisms in urine sediment. Microscopic findings confirm or refute dipstick chemical results.

Lesson 2 • Serous and Synovial Fluid Testing

Introduces pleural, peritoneal, pericardial, and synovial fluid analysis including Light's criteria. Students differentiate transudates from exudates and identify crystal arthropathies.

Lesson 3 • Cerebrospinal Fluid Analysis

Covers cell count, protein, glucose, and culture of CSF for meningitis and other CNS conditions. CSF analysis requires rapid, accurate processing to guide urgent treatment.

Lesson 4 • Routine Urinalysis Methodology

Covers physical appearance, dipstick chemistry, and quality control for routine urinalysis. Students perform and verify each step before advancing to microscopy.

Lesson 1 • Critical Values and Urgent Communication

Establishes protocols for identifying, verifying, and reporting life-threatening results. Timely critical value communication is a direct patient safety requirement.

Lesson 2 • Sensitivity, Specificity, and Predictive Value

Applies diagnostic statistics to evaluate test performance in different prevalence settings. Students select tests based on clinical context rather than catalog descriptions alone.

Lesson 3 • Case-Based Diagnostic Problem Solving

Applies all prior chapter skills to complex patient cases requiring multi-step reasoning. Students demonstrate mastery by generating and defending diagnostic conclusions.

Lesson 4 • Integrating Multi-Panel Results

Teaches simultaneous interpretation of hematology, chemistry, and microbiology data for a single patient. Integration skills distinguish expert practitioners from single-discipline technicians.
