Chapter 1 Flashcards
Blood Sample
A portion of blood removed that is small enough so as not to cause harm
Venipuncture
Withdrawing a venous blood sample using a needle attached to an evacuated tube system or other collection devices
Skin (Dermal) Puncture
Puncturing a finger with a specially designed safety lancet to withdraw a smaller amount of capillary blood
Blood Specimen
A discrete portion of blood taken for laboratory purposes of one or more characteristics to determine the character of the whole body
Give three things laboratory test results are used for.
Diagnostic evaluation, therapeutic assessments, and monitoring health status.
Screening Tests
Laboratory tests that give a “positive” or “negative” result
Qualitative Tests
Lab tests that do not provide a specific measure of a substance, only and indicated “positive” when the result is within a range of values.
Quantitative Tests
Provide exact measurements of a substance in the blood.
Phlebotomist
Blood collector
True or False: Phlebotomists assist in the collection and transportation of specimens other than venous blood.
True. Eg. arterial blood, urine, tissues, and sputum.
Preexamination (Preanalytical) Phase
The part of the process that occurs before the actual testing and analysis are performed.
What are the three phases of specimen collection? Give an example of what is included in each.
1) Preexamination (preanalytical) - Lab requests, labeling the specimen, post-puncture care, processing the specimen.
2) Examination (analytical) - Using appropriate equiptment, reviewing and verifying results, reconciling discrepancies
3) Postexamination (postanalytical) - Entering critical lab data, storing specimens appropriately, defining and adhering to turnaround times
What kind of care does “Point of Care” include?
Includes low-risk lab tests or clinical procedures such as glucose screening, hematocrit, fecal occult blood tests, urine dipsticks, and etc.
What does POCT stand for?
Point-of-care-testing.
What does EKG stand for?
Electrocardiogram.
Acute-care hospitals, specialty hospitals, hospital-based clinics, hospital-based emergency centers
Hospital (Inpatient) Settings
Community health centers, mobile vans for blood donation, fertility clinics, free-standing surgical centers, rural health clinics, specialty practices, and etc.
Ambulatory Care (Outpatient) Settings
Pathologist
Physicians who have extensive training in pathology (study and diagnosis of disease)
Administrative/Management Staff
Individuals who may have a graduate degree in health care administration or business
Technical Supervisors
Medical lab scientists with additional experience and education in a lab specialty area, such as hematology, microbiology, or clinical chemistry
Medical Laboratory Scientists (MLS)
Certified professionals with a bachelor’s degree in a biological science
