ABPath Chemical Pathology study plan

ABPath Chemical Pathology · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Disorders of metabolism & Electrolyte and acid/base disorders

  • Map each major metabolic disorder class (carbohydrate, lipid, amino acid, porphyria, storage) to its diagnostic analytes and confirmatory tests

  • Derive and practice the anion gap, delta gap, and osmolal gap calculations on 20 constructed cases

  • Build a one-page algorithm distinguishing respiratory vs metabolic acid-base disturbances using compensation formulas

  • Explain the laboratory workup sequence for suspected inborn error of metabolism in a decompensating neonate

  • Self-quiz 40 mixed metabolism and electrolyte items and log every miss with the underlying concept

Your checkpoint

Two-page metabolic and acid-base reference sheet plus an error log of at least 15 missed concepts

Week 2

Disorders of metabolism & Electrolyte and acid/base disorders

  • Interpret 25 practice vignettes on electrolyte disorders (sodium, potassium, calcium, magnesium, phosphate) and justify the calculated expected values

  • Compare laboratory findings that separate SIADH, diabetes insipidus, and primary polydipsia

  • Rehearse the diagnostic pathway for hypoglycemia workup including the supervised fast and C-peptide interpretation

  • Summarize specimen-handling pitfalls that falsely alter potassium, calcium, and ammonia results

Your checkpoint

Completed 25-case electrolyte worksheet with written rationale for each answer

Week 3

Serum protein and hemoglobin abnormalities & Disorders of coagulation and hemostasis

  • Differentiate monoclonal gammopathy patterns on serum and urine protein electrophoresis with immunofixation on 15 constructed cases

  • Sequence the laboratory evaluation of a prolonged PT or aPTT using mixing studies and factor assays

  • Explain the interpretive logic behind lupus anticoagulant testing and thrombophilia panels

  • Describe hemoglobin variant detection by electrophoresis, HPLC, and solubility testing and when each is indicated

  • List preanalytical variables that invalidate coagulation results and state the corrective action for each

Your checkpoint

Flowchart set for protein electrophoresis interpretation and for prolonged PT/aPTT investigation

Week 4

Analytic methods and techniques & Instrumentation and equipment

  • Compare analytical principles of spectrophotometry, immunoassay, chromatography, mass spectrometry, and electrophoresis by sensitivity, interference, and use case

  • Identify the failure modes and maintenance requirements of common analyzers, centrifuges, and pipetting systems

  • Calculate and interpret absorbance, molar absorptivity, and calibration curve linearity problems

  • Explain method validation elements: accuracy, precision, linearity, limit of detection, interference, and reference interval verification

Your checkpoint

Method-comparison table covering 10 analytical techniques plus 10 solved instrumentation calculation problems

Week 5

Quality control and quality management & Calculations and statistics

  • Construct Levey-Jennings charts and apply Westgard multirules to 20 simulated QC data sets

  • Calculate mean, SD, CV, and z-scores by hand and verify with a spreadsheet

  • Interpret proficiency testing failures and draft a corrective action sequence

  • Solve statistical problems on sensitivity, specificity, predictive value, ROC comparison, and reference interval determination

  • Distinguish internal QC, external QC, and quality assurance activities and assign each to the correct monitoring cycle

Your checkpoint

QC workbook with 20 rule-application answers and a written corrective-action template

Week 6

Laboratory administrative and management requirements and practices & Patient preparation and specimen collection & Standards and units of measurement

  • Outline regulatory and accreditation requirements governing clinical chemistry laboratories and match each to its oversight body

  • Design a phlebotomy and specimen-rejection workflow that addresses patient identification, timing, and collection-tube order

  • Convert between conventional and SI units for 25 common analytes and state reference-interval implications

  • Explain reporting-critical-value policies and the documentation chain of custody for toxicology specimens

  • Draft a budget and staffing justification for a new chemistry analyzer using workload units

Your checkpoint

Administrative packet containing a unit-conversion table, a specimen-rejection policy, and a one-page analyzer justification memo

Week 7

Clinical laboratory evaluation of organ and systemic diseases; reproduction, pregnancy, and newborn screening and monitoring; point-of-care testing; infectious disease serology and disorders of the immune system; toxicology, drug misuse, and therapeutic drug monitoring; patient care decision-making and consultation

  • Map laboratory panels to organ systems: cardiac, hepatic, renal, pancreatic, and endocrine markers with their diagnostic windows

  • Sequence prenatal, pregnancy, and newborn screening tests and state the timing and follow-up for each abnormal result

  • Compare point-of-care testing devices to central laboratory methods on accuracy, connectivity, and operator requirements

  • Interpret infectious disease serology patterns including acute vs convalescent titers, IgM pitfalls, and autoimmune serologies

  • Apply therapeutic drug monitoring principles: timing of levels, half-life, steady state, and free vs total drug interpretation

Your checkpoint

Organ-system and special-population test-selection guide with 30 mapped clinical scenarios
