Study Notes
- Medical laboratory science (MLS) entails analyzing human biological specimens using various analytical techniques.
- MLS results are crucial for the diagnosis, treatment, and monitoring of disease.
- MLS professionals need in-depth knowledge of basic sciences, laboratory instrumentation, and quality control.
- Training for MLS professionals includes academic study and clinical laboratory experience.
- MLS professionals play a critical role in healthcare.
- Common laboratory departments are clinical chemistry, hematology, microbiology, and transfusion medicine.
- Clinical chemistry analyzes bodily fluids for chemical components.
- Hematology focuses on the study of blood and bone marrow.
- Microbiology involves identifying microorganisms that cause disease.
- Transfusion medicine deals with blood banking and blood transfusions.
- Other areas in MLS include immunology, molecular diagnostics, and urinalysis.
- Immunology studies the immune system and its response to diseases.
- Molecular diagnostics utilizes molecular biology techniques to diagnose and monitor diseases.
- Urinalysis involves the analysis of urine for diagnostic purposes.
- Lab safety is a top priority, including handling biohazardous materials, following safety protocols, and using personal protective equipment (PPE).
- Quality control ensures the accuracy and reliability of test results.
- Quality assurance encompasses all activities to ensure the quality of laboratory services.
- Pre-analytical factors involve all steps before sample analysis, including test ordering and sample collection.
- Analytical factors are related to the testing process itself.
- Post-analytical factors involve result reporting and interpretation.
- Laboratory results must be accurate, precise, and reliable.
- Accuracy is the closeness of a measured value to its true value.
- Precision is the reproducibility of a measurement.
- Reliability refers to the overall consistency of a test.
- Reference ranges are used to interpret laboratory results, established by testing a healthy population.
- Deviations from reference ranges can indicate disease.
- Laboratory information systems (LIS) manage patient data and test results.
- LIS aids in workflow management and quality control.
- Ethical conduct is essential for MLS professionals.
- MLS professionals must maintain patient confidentiality, adhere to professional standards, and provide accurate and reliable results.
- Continuing education is important for staying current in the field because new technologies and techniques are constantly emerging in MLS.
- MLS professionals must adapt to changes in the field to provide the best patient care.
- Medical laboratory science is a dynamic and challenging field and MLS professionals make a real difference in patient care.
- Specimen collection is a critical pre-analytical step; proper collection techniques ensure the integrity of samples.
- Common specimen types include blood, urine, and swabs.
- Blood collection usually involves venipuncture, performed by phlebotomists or other trained personnel.
- Urine samples are collected in clean containers.
- Swabs are used to collect samples from various body sites.
- Each department uses specific techniques and instruments.
- Clinical chemistry uses spectrophotometry and chromatography.
- Hematology uses automated cell counters and microscopy.
- Microbiology uses culture techniques and staining methods.
- Transfusion medicine uses blood typing and crossmatching.
- Automation has revolutionized medical laboratories; automated instruments increase efficiency and reduce errors.
- Automation requires trained personnel to operate and maintain the equipment.
- Point-of-care testing (POCT) brings testing to the patient bedside, providing rapid results for timely clinical decisions.
- POCT requires strict quality control measures.
- Molecular diagnostics plays an increasing role in disease diagnosis.
- Molecular techniques include PCR and gene sequencing.
- Molecular diagnostics can detect infectious diseases and genetic disorders.
- Quality control materials are used to monitor test performance.
- Control samples have known values and are run alongside patient samples.
- Statistical analysis is used to evaluate quality control data.
- Laboratory accreditation ensures compliance with quality standards through regular inspections and audits.
- Accreditation is performed by organizations like the College of American Pathologists (CAP).
- The role of the MLS professional is evolving; they are increasingly involved in data analysis and interpretation.
- MLS professionals may specialize in specific areas of the laboratory.
- Strong communication skills are essential for MLS professionals.
- MLS professionals must communicate results to physicians and other healthcare providers and document findings accurately and completely.
