Study Notes
Blood Banking and Specimen Collection
- Blood bank tests typically require lavender or pink top EDTA tubes for collection.
- For fever of unknown origin (FUO), two or three cultures should be collected consecutively from different sites to ensure accurate results.
Pediatric Considerations
- The same antiseptic methods for blood culture skin preparation used for adults can also apply to pediatric patients, except when using tincture or iodine as antiseptic.
Skin Antisepsis Techniques
- To reduce contamination risks from skin flora when collecting specimens, sites should undergo a 30 to 60 second friction scrub to effectively reach bacteria beneath dead skin cells.
RNA Testing
- Blood specimens for RNA tests must be sent for testing immediately or collected in a special stabilizing reagent to preserve RNA integrity.
Trace Element Testing
- For trace element tests, it is recommended to draw the specimen by itself using a needle and tube assembly to prevent contamination from other tests.
Coagulation Specimens
- Coagulation specimens drawn through vascular access devices (VADs) require discarding blood that is six times the dead space volume of the tubing, roughly 5 mL, to ensure accurate readings.
Glucose Tolerance Test (GTT) Protocol
- During a Glucose Tolerance Test (GTT), the patient must refrain from drinking beverages or chewing gum, as these activities can activate the digestive process and affect test results.
Paternity Testing Samples
- Blood samples are preferred for paternity testing; however, buccal swabs are increasingly utilized due to their convenience and effectiveness.
Drug Screening Preferences
- Drug screening tests are primarily conducted on urine rather than blood, as urine is more accessible for collection and can detect a wider variety of drugs and their metabolites over a longer period.
