Study Notes
Infection Control
- A susceptible host is an individual with little resistance to infectious microbes.
Work Practice Control
- Wearing gloves during blood draws is an effective measure to reduce exposure to bloodborne pathogens.
Coagulation
- Calcium is an essential ion for the coagulation process.
Quality Control
- Outdated evacuated tubes can lead to incomplete filling, affecting additive-to-sample ratios.
Molecular Testing
- Molecular genetic testing requires specimens to be collected in sterile EDTA tubes.
Antiglycolytic Agent
- The purpose of an antiglycolytic agent is to preserve glucose levels in specimens.
Blood Collection Order
- When using an evacuated tube system, a blood culture (SPS) tube is filled first.
Blood Culture Disinfection
- Chlorhexidine gluconate is the recommended disinfectant for blood culture sites in infants aged 2 months and older.
Fibrin Formation
- Latent fibrin formation in serum may occur due to incomplete clotting during centrifugation.
Capillary Specimen Collection
- The order of draw differs when collecting capillary specimens compared to routine venipuncture for tests like BUN and CBC.
Preanalytical Errors
- An example of a preanalytical error is failing to adequately mix tubes after collection.
Modified Allen Test
- A positive modified Allen test is characterized by the hand color returning to normal within 15 seconds.
Tube Handling
- Nonanticoagulant gel tubes should be placed upright immediately after mixing, per CLSI guidelines.
Capillary vs. Venous Values
- Reference values for glucose are typically higher in capillary specimens compared to venous specimens.
Serum Separation
- CLSI advises that serum or plasma should be separated from cells within 2 hours of collection.
Transporting Samples
- Transporting tubes with stoppers up does not ensure sterility of the sample.
Serum Definition
- The liquid portion of a clotted specimen is termed serum.
Glucose Monitoring
- The primary reason for glucose monitoring through point-of-care testing (POCT) is to manage diabetes.
Certification Agencies
- AMT, ACA, and ASCP are organizations that certify laboratory professionals.
Blood Culture Errors
- Improper cleansing of the collection site is a frequent error in blood culture collection.
Urinalysis Specimen
- A random specimen is commonly used for routine urinalysis.
FIT Test Indication
- A positive FIT (Fecal Immunochemical Test) indicates potential bleeding in the colon or rectum.
Specimen Accessioning
- Accessioning involves connecting a specimen with an individual, assigning a unique identification number, and recording its receipt.
Plasma Definition
- The liquid portion above centrifuged cells in a non-gel tube is referred to as plasma.
Capillary Blood Composition
- Blood obtained via capillary puncture closely resembles arterial blood in composition.
Post-Prandial Glucose Collection
- If a phlebotomist arrives before the 2-hour mark for a post-prandial glucose test, they should verify the timing with the patient's nurse.
Heart Anatomy
- The left ventricle serves as the delivering chamber of the heart.
Sample Volume Requirement
- For a chemistry test requiring 0.5mL of serum, a 3-mL red top tube is the minimum acceptable size to meet the specimen volume requirement.
Phlebotomy Malpractice Standards
- Standards of care in phlebotomy malpractice cases often rely on guidelines from the Clinical and Laboratory Standards Institute (CLSI).
