W3 introduction to clinical laboratory Flashcards
what is MLA primary responsibility in lab
procurement and preparation of specimens for analysis in lab
- -patient info management using LIS
- prepare reagent and quality control
- qc activities
- load specimens
- prepare slide or tissue
- inoculating and incubating micro
collection sites
no testing
phlebotomy
pic
specimen collection centres
rapid response laboratories
hospital setting
labs perform priority testing
short TAT
high volume lab
specialized procedures- high volume lots of the same sample
doc- diagnostic and scientific centre
reference lab or provincial labs
complex testing procedures -mayo clinic
departments within a clinical lab
specimen accessioning chemistry and urinalysis hem and coag transfusion med (immunohematology) microbiology histology (`anatomic pathology)
what does mla do in chemistry and urinalysis
largest most automated concentration of various chemical of different body fluid, mostly blood (glucose cholesterol triglycerides MINT TOP pst usually or GOLD TOP sst both centrifuged in order to test urinalysis too
hem coat
study of formed elements of blood(erythrocytes,luekocytes,thrombocytes)
-perform cbc, white cell differential
ESR (erythrocyte sedimentation rate
LAV tubes
-bone marrow anaylised too
coag- bleeding and clotting issues — pt prothrombin time and activated portial thromboplastin time and fibrinogen –BLUE -looking for clotting disorders.
what do MLAs do in hem or coag
centrifuge coag specimens and load hematology and coagulation analyzers and make peripheral blood films and ESR testing
transfusion medicine or immunohematology
provide blood components to patients who need them
-rbc, plasma. platelets, serum, coagulation factors, albumin
type o,a,b,ab and then rh pos or rh neg
*most of testing based on antigen-antibody reactions
micro
bacteria, fungi, parasites and viruses —–identify pathogen
bacteria- culture and sensitivity
-take swab from wound, abscess, throat, nose, eye, vagina,, urin, cerebrospinal fluid, sputum, stool and blood
what do MLAs do in micro
planting specimens and incubating appropriately
histology and cytology
study of tissue structure
biopsy autopsy-cut into thin sections and stained then examined microscopically by a technologist or pathologist
cytology-anatomic pathology in which structural changes in cells are evaluated to detect and diagnose cancer
what do MLAs do in histology or cytology
prepare and stain
maintain instruments
prepare reagents
filing slides and tissue as well as waste management
