Medical Laboratory Technology

Clinical Microbiology

• Focuses on the diagnosis and management of infectious diseases.
• Involves the study of bacteria, viruses, fungi, and parasites.
• Key Techniques:
  • Culture Techniques: Growing pathogens in controlled environments.
  • Microscopy: Using light or electron microscopes to identify microorganisms.
  • Molecular Methods: Techniques like PCR for detecting genetic material of pathogens.
• Important Tests:
  • Antimicrobial susceptibility testing to determine effective treatments.
  • Serological tests to identify antibodies or antigens.

Biochemistry

• Studies the chemical processes within and related to living organisms.
• Involves analysis of bodily fluids (e.g., blood, urine) for diagnostic purposes.
• Key Components:
  • Enzymes: Assessing activities for metabolic disorders.
  • Electrolytes: Monitoring levels (sodium, potassium) for organ function.
  • Metabolites: Analyzing substances produced during metabolism (e.g., glucose).
• Common Tests:
  • Liver function tests to evaluate liver health.
  • Kidney function tests (e.g., creatinine, BUN).

Hematology

• Focuses on blood and its disorders.
• Analyzes components like red blood cells, white blood cells, platelets, and plasma.
• Key Tests:
  • Complete Blood Count (CBC): Provides information on blood cell levels and types.
  • Coagulation Studies: Assessing blood clotting ability (e.g., PT, aPTT).
  • Bone Marrow Analysis: Evaluates blood cell production and health.
• Important Conditions:
  • Anemias: Disorders characterized by low red blood cell counts.
  • Leukemias: Cancers of blood-forming tissues.

Pathology

• The study of disease, its causes, and effects on the body.
• Involves examination of tissues (histopathology) and body fluids.
• Types of Pathology:
  • Anatomic Pathology: Includes surgical pathology and cytology.
  • Clinical Pathology: Involves laboratory analysis of blood and other fluids.
• Key Techniques:
  • Biopsy: Removing tissue for examination.
  • Autopsy: Post-mortem examination to determine cause of death.
• Important Concepts:
  • Disease processes: Understanding how diseases develop and progress.
  • Diagnostic criteria: Establishing guidelines for identifying diseases.

Clinical Microbiology

• Diagnose and manage infectious diseases through various techniques.
• Study of microorganisms: bacteria, viruses, fungi, and parasites.
• Key techniques include:
  • Culture Techniques: Cultivating pathogens in controlled environments to obtain isolates.
  • Microscopy: Utilizing light or electron microscopes for identification and observation of microorganisms.
  • Molecular Methods: Employing techniques such as PCR to detect and analyze genetic material from pathogens.
• Important tests conducted:
  • Antimicrobial Susceptibility Testing: Determines effective antibiotics for treatment of infections.
  • Serological Tests: Identify presence of antibodies or antigens in patient samples.

Biochemistry

• Focus on chemical processes in living organisms with a primary emphasis on diagnostic analysis of bodily fluids.
• Key components analyzed include:
  • Enzymes: Evaluating enzyme activities helps diagnose metabolic disorders.
  • Electrolytes: Monitoring levels of key electrolytes like sodium and potassium to assess organ function.
  • Metabolites: Analysis of metabolic byproducts such as glucose to evaluate metabolic health.
• Commonly performed tests include:
  • Liver Function Tests: Assess overall liver health and function.
  • Kidney Function Tests: Includes measurements of creatinine and BUN to evaluate kidney health.

Hematology

• The study of blood components and associated disorders.
• Analyzes blood elements: red blood cells, white blood cells, platelets, and plasma.
• Key tests in hematology:
  • Complete Blood Count (CBC): Provides a comprehensive overview of blood cell types and levels.
  • Coagulation Studies: Evaluate blood clotting mechanisms (e.g., PT, aPTT) to identify bleeding disorders.
  • Bone Marrow Analysis: Assesses production and quality of blood cells from the bone marrow.
• Important disorders examined include:
  • Anemias: Conditions marked by a deficiency in red blood cells resulting in fatigue and weakness.
  • Leukemias: Blood cancers originating from bone marrow affecting blood cell production.

Pathology

• Examination of diseases, their causes, effects, and underlying mechanisms.
• Involves histopathological investigations of tissues and fluid samples.
• Major types of pathology:
  • Anatomic Pathology: Encompasses surgical pathology and cytology for tissue evaluation.
  • Clinical Pathology: Focuses on laboratory analyses of fluids such as blood for disease diagnosis.
• Essential techniques employed:
  • Biopsy: Removal and examination of tissue samples to diagnose diseases.
  • Autopsy: Investigation post-mortem to ascertain cause of death.
• Crucial concepts include:
  • Disease Processes: Insights into development and progression of diseases.
  • Diagnostic Criteria: Standards established for identifying and classifying diseases accurately.
