SPECIAL COLLECTION AND POINT OF CARE TESTING Flashcards
(52 cards)
Non-routine laboratory tests that may
not only involve additional preparation
and procedure but may require other
specimens such as urine or feces
SPECIAL COLLECTION PROCEDURES
Important in determining which blood
product can be safely used for blood
transfusion
THE BLOOD BANK SPECIMEN
In collecting blood bank specimen, use:
- LAVENDER TOP
- PINK TOP EDTA
- RED-TOP (NON-ADDITIVE)
Use special identification systems such
as ID bracelet (self-carbon adhesive for
specimen), blood ID band (linear barcode), and patient identification
BLOOD BANKS
Conduct tests in the laboratory, These
include typing the blood for transfusion
and screening for infectious diseases
BLOOD BANKS
Done mainly for the purpose of blood
transfusion
BLOOD DONOR COLLECTION
(VOLUNTEER)
Blood donors should be
17 to 66 years of age
Test that checks the blood for
pathogens for patients who have a fever
of unknown origin
BLOOD CULTURE
Existence of bacteria in the blood
BACTEREMIA
Presence of microorganism and toxins
in the blood
SEPTICEMIA
A butterfly and a specially designed
holder are used
DIRECT INOCULATION
Filled first and each container is mixed
after removal from the holder
AEROBIC VIAL
Blood is transferred to the culture
bottles after completing the draw using
a safety transfer device, which is
activated as soon as the needle is
removed from the site
SYRINGE METHOD
Performed in the laboratory rather than
at the patient’s bedside
INTERMEDIATE COLLECTION TUBE
Coagulation tests:
PT, aPTT, TT
This blood test is done to check if the
patient is suffering from diabetes
- 2-hour postprandial glucose (2-hour pp)
- (The patient is on a high-carbohydrate diet 2 to 3 days prior to the test.
- The patient should fast for at least 10 hours before the test)
A patient who could be suffering from
carbohydrate metabolism problems is
subjected to the__, to evaluate the
ability of the body to metabolize glucose
Glucose Tolerance Test (GTT)
- Before, patient must eat a balanced
meal containing approximately 150
grams of carbohydrates for 3 days
Measures the ability of the body to
process lactose and determines if the
patient lacks mucosal lactase, which is
an enzyme that converts lactose into
glucose or galactose
LACTOSE TOLERANCE TEST
Performed to exclude the possibility of
paternity of a particular child
PATERNITY/PARENTAGE TESTING
Before the advent of DNA parenting
testing, testing for parentage involves
ABO, Rh TYPING
Uses genetic fingerprinting or DNA
profiling to establish parentage by
providing genetic proof
DNA PATERNITY TESTING
Measures drug levels at designated
intervals so that the appropriate
dosage can be established and maintained for the patient, thus avoiding toxicity
THERAPEUTIC DRUG MONITORING
Performed by drawing a LARGE VOLUME OF
BLOOD about 500 mL from the patient as
part of the treatment procedure for
polycythemia and hemochromatosis
THERAPEUTIC PHLEBOTOMY
Overproduction of red blood cells that is
harmful to the patient
POLYCYTHEMIA
