MT MLO study plan

MT MLO · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Bacteriology: isolation, identification, and antimicrobial susceptibility testing

  • Map the bacteriology workflow from specimen plating through isolate identification, writing a one-page decision tree for how Gram stain, colony morphology, and biochemical reactions narrow an unknown organism.

  • Build a personal table of 25 clinically important organisms listing expected Gram reaction, oxygen requirement, key biochemical reactions, and the single most useful confirmatory test for each.

  • Explain aloud, without notes, how to interpret a susceptibility panel including MIC, breakpoint categories, and the difference between intrinsic and acquired resistance.

  • Solve 30 practice-style case vignettes that require choosing the next identification or susceptibility step and log every miss with the reason it was missed.

Your checkpoint

A completed 25-organism identification table plus a scored 30-question self-test log showing at least 80% accuracy.

Week 2

Bacteriology: isolation, identification, and antimicrobial susceptibility testing

  • Describe the mechanisms and laboratory detection methods for the major resistance phenotypes, including MRSA, VRE, ESBL, AmpC, and carbapenemase producers, in a written summary.

  • Compare phenotypic confirmation methods such as disk diffusion, gradient diffusion, and automated systems, stating at least two limitations of each.

  • Practice interpreting quality-control ranges for reference strains and identify what corrective action follows an out-of-range result.

  • Work through 20 organism-identification flowcharts from a single clue such as a positive catalase or oxidase result until each branch is justified.

Your checkpoint

A one-page resistance-mechanism and detection cheat sheet, self-quizzed to 90% recall on a written recall test.

Week 3

Pre-analytical considerations: specimen collection, handling, and rejection criteria & Laboratory operations: quality control, quality assurance, and safety

  • List collection, transport, and rejection criteria for blood, CSF, sputum, urine, wound, and stool specimens, and justify each criterion by the organism or artifact it protects.

  • Sequence the pre-analytical steps where errors most often occur and rank them by impact on culture yield.

  • Outline the components of a quality-assurance program covering media QC, equipment calibration, proficiency testing, and document control.

  • Apply standard precautions and biosafety level requirements to three scenarios involving aerosol risk, sharps, and spill cleanup.

Your checkpoint

A specimen rejection criteria reference card covering six specimen types, plus a 15-question pre-analytical and safety quiz scored at 85% or better.

Week 4

Mycology & Parasitology

  • Differentiate the major medically important fungi by colony and microscopic morphology, including dimorphic pathogens, yeasts, and opportunistic molds.

  • Describe the role of culture, antigen detection, and molecular methods in diagnosing invasive fungal infection and state when each is preferred.

  • Identify the medically important protozoa and helminths by diagnostic stage, specimen source, and the single best detection method.

  • Explain the procedures and limitations of the O&P exam, including concentration techniques and permanent stained smears.

  • Interpret five parasitology or mycology case scenarios and select the appropriate follow-up test.

Your checkpoint

A two-part morphology atlas summary for fungi and parasites, with 20 self-written identification questions answered at 80% or better.

Week 5

Mycobacteriology and Nocardia & Virology and molecular diagnostics

  • Describe the specimen processing, decontamination, staining, and culture requirements for mycobacteria and explain how they differ from routine bacteriology.

  • Distinguish Nocardia from Mycobacterium and Streptomyces by staining, growth characteristics, and biochemical or molecular findings.

  • Compare molecular amplification, sequencing, and hybridization methods for organism detection and viral load monitoring, stating one strength and one limitation of each.

  • Outline the diagnostic approach to common viral syndromes including respiratory, hepatitis, and CNS infections, naming the preferred specimen and method for each.

  • Explain quality-control and contamination-prevention practices specific to molecular testing.

Your checkpoint

A side-by-side comparison sheet for mycobacteria, Nocardia, and common viral diagnostic algorithms, validated by a 20-question mixed quiz at 80% or better.

Week 6

Bacteriology: isolation, identification, and antimicrobial susceptibility testing & Pre-analytical considerations: specimen collection, handling, and rejection criteria

  • Re-attempt every missed question from weeks 1 through 5 and record the corrected reasoning for each.

  • Build 40 new mixed-domain practice questions weighted toward bacteriology and pre-analytical content and answer them under timed conditions.

  • Review any organism or criterion still uncertain and reduce the open-issue list to no more than five items.

Your checkpoint

A corrected error log with written reasoning for every previously missed item and a timed 40-question score of at least 80%.

Week 7

Laboratory operations: quality control, quality assurance, and safety & Laboratory management, regulatory compliance, and education

  • Summarize the regulatory framework governing clinical laboratories, including accreditation, personnel qualification, and proficiency testing requirements.

  • Explain how to design and document a quality-improvement project, including indicator selection, data collection, and corrective action.

  • Describe the elements of an effective training and competency assessment program for laboratory staff.

  • Outline safety program components covering chemical hygiene, fire safety, and exposure control plans.

  • Analyze two management scenarios involving staffing, workflow, or compliance and propose a defensible action plan.

Your checkpoint

A one-page quality-improvement project outline with measurable indicators, plus a 15-question operations and management quiz at 85% or better.

Week 8

Pre-analytical considerations: specimen collection, handling, and rejection criteria & Bacteriology: isolation, identification, and antimicrobial susceptibility testing & Mycobacteriology and Nocardia & Mycology & Parasitology & Virology and molecular diagnostics & Laboratory operations: quality control, quality assurance, and safety & Laboratory management, regulatory compliance, and education

  • Take two full-length timed practice exams and record domain-level scores to identify remaining weak areas.

  • Review every missed item from both exams and close each gap with a written explanation grounded in the underlying principle.

  • Recite the highest-yield facts for each domain from memory in a rapid self-quiz covering at least 50 items.

  • Finalize a one-page summary sheet of the most confusable pairs and criteria across all eight domains.

Your checkpoint

Two completed timed practice exams with domain score breakdowns and a finalized one-page high-yield summary sheet.

Milestones

Week 2: Score 80% or better on a 30-question bacteriology self-test and demonstrate recall of the 25-organism identification table without notes.

Week 4: Score 85% or better on the pre-analytical and safety quiz and 80% or better on the combined mycology and parasitology question set.

Week 6: Timed 40-question mixed exam scored at 80% or better with every previously missed item re-explained in writing.

Week 8: Both full-length practice exams completed within time limits with an overall score of at least 80% and no single domain below 70%.
