(F) Lesson 1: Non-Blood Specimen Handling and Processing Flashcards
(247 cards)
Liquid or semi-liquid substances produced by the body and are found within various organs and body spaces
Non-blood specimens
T or F: Most non-blood specimens can be collected by a phlebotomist
False (most are only for physicians)
When a phlebotomist gives instructions regarding specimen collection, what 2 types of instruction should be given?
Oral and written (with illustrations)
T or F: You may verify proper labelling after accepting a specimen for transport
False (before accepting)
T or F: Initials of the phlebotomist are needed when labelling non-blood specimens
False
Where should the label be pasted on the container?
Body; not the lid (risk for interchanging samples as lids are removed during testing)
T or F: Phlebotomists must treat all body substances as potentially infectious
True
What is the most frequently analyzed non-blood body fluid?
Urine
How many hours before a urine sample deteriorates?
2 hours
This is the most commonly requested urine test
Routine urinalysis
T or F: Routine urinalysis is not part of a physical exam
False
This type of analysis for urine samples utilizes observation with the naked eye
Physical or macroscopic observation
This macroscopic observation tells us about the degree of hydration
Color
A darker urine color indicates what?
Concentrated sample due to dehydration
This macroscopic observation is aka transparency
Clarity
A turbid urine sample indicates the presence of what?
Bacteria, WBCs, etc.
What 2 methods measure specific gravity?
Urinometry and Refractory
What 2 macroscopic parameters measure urine concentration
Specific gravity and osmolality
High specific gravity means what in terms of concentration?
Concentrated
T or F: Odor, volume, and osmolality are considered routine urinalysis procedures
False
This macroscopic parameter is only measured if the tests are for quantitative analysis
Volume
This macroscopic parameter can also measure the degree of hydration (other than color) of the specimen as it is more preferred yet more expensive
Osmolality
T or F: Urine should be transported at room temperature
False (with ice)
T or F: Outpatient urine samples are handled by nurses
False (nurses handle inpatient samples while technicians handle the outpatient samples)
