Study Notes
Forensic Toxicology
- Forensic toxicology involves the legal implications of toxin exposure.
Blood Culture Collection
- When collecting blood cultures, if only one bottle can be filled, prioritize adding to the aerobic bottle.
- Correct order for blood culture collection: select equipment, perform friction scrub, cleanse bottle tops, and perform venipuncture.
- Pediatric blood culture challenges arise due to prior antibiotic administration.
- Initial specimen diversion is a technique used when collecting blood cultures.
Lactose Tolerance Test
- The lactose tolerance test assesses if a patient lacks the enzyme to convert lactose into glucose and galactose.
Parentage Testing
- Blood samples are the preferred specimens for parentage testing.
- A child who is a minor cannot order paternity testing.
Blood Donation and Transfusions
- Autologous donation acknowledges that unused units are not shared with other patients.
- Blood transfusions may be fatal if incompatible blood is given due to red blood cell lysis.
- TDM (therapeutic drug monitoring) helps maintain appropriate drug dosages across various medications.
Blood Specimen Collection and Tests
- The phosphate additive in blood ensures plasma pH stability.
- Coagulation testing requires a specific ratio of blood to anticoagulant in the specimen tube.
- Blood alcohol specimens can be cleaned using Zephiran chloride.
- Tests like hemoglobin A1c are essential for managing diabetes and monitoring treatment effectiveness.
- Collection of multiple specimens is necessary for glucose tolerance tests (GTT).
Glucose Metabolism
- Hyperglycemia indicates increased blood glucose levels.
- Glucose levels typically peak 30 to 60 minutes after ingestion.
- Timing of specimen collection during GTT begins after the glucose beverage is finished.
- Patients complete meals with controlled carbohydrate intake 3 days prior to GTT for accurate results.
Point-of-Care Testing (POCT)
- Popular tests include glucose monitoring for diabetic management and cardiac assessments using TnT and B-type natriuretic peptide.
- POCT can use diverse blood sample types, allowing devices to download data and verify operator IDs for security.
- HemoCue HB201+ uses microcuvettes for testing instead of traditional strips.
Infection and Sepsis Monitoring
- Lactate levels serve as markers for sepsis severity.
- Septicemia refers to the presence of microorganisms in the bloodstream.
Anemia and Hematology
- Hemoglobin is crucial in anemia management.
- Blood specimens for lead analysis require tan-top tubes with K2EDTA.
Miscellaneous
- Chain-of-custody protocols apply to forensic specimens, ensuring integrity during testing.
- Rapid tests like those for syphilis detect specific pathogens like Treponema pallidum.
- Good cholesterol is represented by HDL, while drugs like phenobarbital are not categorized as typical abuse substances.
