Cambodia Laboratory Exit Exam study guide
Cambodia Laboratory Exit Exam · Work through your exam, one topic at a time.
The Cambodia Laboratory Exit Exam is the final assessment for students completing a medical laboratory technology program in Cambodia. It is designed to ensure that graduates have the knowledge and skills required to practice safely and effectively in clinical laboratories. The Cambodia Laboratory Exit Exam study guide has 10 sections and about 2,496 words.
01Clinical Chemistry
Clinical chemistry in this exit exam tests the full testing pathway - patient preparation, specimen collection and transport, calibration, internal quality control, reference intervals and safe interpretation of electrolyte, renal, liver, glucose and lipid results in Cambodian hospital laboratories. Follow the standard order of draw: blood culture, citrate, serum separator, heparin, EDTA, fluoride-oxalate.
263 words, about 1 min02Hematology and Blood Transfusion Science
Haematology and transfusion science questions cover CBC interpretation, anaemia classification, coagulation testing, ABO/Rh grouping, antibody screening, crossmatching and transfusion reaction investigation, with attention to Cambodia's hospital blood banks and the National Blood Transfusion Centre. Verify patient identity and sample labelling at the bedside; a mislabelled pretransfusion sample is never acceptable.
260 words, about 1 min03Medical Microbiology (Bacteriology, Virology, Mycology)
Medical microbiology tests bacteriology, virology and mycology: specimen selection, Gram stain, culture, identification, antimicrobial susceptibility testing, and interpretation of TB, HIV viral load and fungal investigations relevant to Cambodia. Collect specimens before antibiotics whenever possible and transport in the correct medium and temperature.
251 words, about 1 min04Parasitology and Medical Entomology
Parasitology and medical entomology questions test malaria diagnosis and parasite counting, stool examination for helminths and protozoa, and vector identification relevant to dengue, malaria and lymphatic filariasis in Cambodia. Use thick films for detection and thin films for species identification; examine at least 100 fields before reporting negative.
251 words, about 1 min05Clinical Immunology and Serology
Clinical immunology and serology questions test immunoassay principles, HIV and syphilis testing algorithms, dengue serology, autoimmune markers and the interpretation of antibody and antigen results in the Cambodian laboratory. Follow the national testing algorithm; a reactive screening test is confirmed by a second assay of different format or by nucleic acid testing.
254 words, about 1 min06Laboratory Management
Laboratory management questions test quality management systems, ISO 15189 principles, document control, personnel competence, equipment and inventory management, POCT oversight and corrective action in resource-limited Cambodian laboratories. Every procedure must be a controlled document with version, approval date and review date.
240 words, about 1 min07Quality Assurance and Biosafety
Quality assurance and biosafety questions test internal QC rules, external quality assessment, biosafety levels, personal protective equipment, spill management and safe waste handling in Cambodian laboratories. Run two QC levels and apply Westgard rules before releasing patient results.
259 words, about 1 min08Laboratory Instrumentation, Techniques and Diagnostic Accuracy
This domain tests spectrophotometry, centrifugation, pipetting, calibration, and the diagnostic accuracy concepts of sensitivity, specificity, predictive values and likelihood ratios used to judge laboratory tests. Beer-Lambert law: absorbance is proportional to concentration and path length at a fixed wavelength.
226 words, about 1 min09Public Health Laboratory Practice and Disease Surveillance
Public health laboratory questions test notifiable disease reporting, case definitions, outbreak investigation, specimen referral and surveillance data quality in Cambodia's provincial and national system. Use the national case definition before classifying a case; do not change it mid-outbreak without documenting the reason.
237 words, about 1 min10Professional Ethics, Communication and Health Law
Ethics, communication and health law questions test informed consent, confidentiality, mandatory reporting, scope of practice, critical result communication and respectful patient interaction under Cambodian health law and professional codes. Obtain informed consent before invasive sampling or research; explain purpose, risks and alternatives in a language the patient understands.
