introduction to vet leb Flashcards
what are the different types of labs
in house, referral
what are the advantages and diadvantages of referral labs
adv:high quality equiptment and specially trained staff- better validity of results
-can perform difficult/ unusual teste
-lab often employ veterinary pathologies who can give more medical information from test results
disadvantage:
-takes longer time to get results, delays diagnosis
-storage and transportation measures needs to be considered
-may not be readily available
-often more expensive for client
advantages and disadvantages of in house testing
adv:
-get results fast, reach diagnosis fast
-samples fresh when examined so less artidacts or unusable material
-good revenue for clinic
-often cheaper for clinics
disadv:
-equiptment expensive to purchase
-requires staff to be trained to run and maintain equiptment
-need dedicated space to be allocated for machines
what affects quality of results
Quality of sample (Pre-analytical)
-Sample collection, handling, storage, dispatching
- Quality of analysis (Analytical)
-Instruments/Equipments –maintained, calibrated?
-Reagents
-Lab technique- protocol, operator skill
Suitability for species - Quality of patient’s lab records (Post-analytical)
-Transcription errors when reporting
equiptment for running heamatology tests
-blood tubes
-centrifuge machine (spin down blood to seperate blood into its compoents)
-haematology machine (to run CBC)
-microhamatocrit tubes (calculate packed cell volume and total protein)
-SNAP test (to test for various diseases)
equiptment for running blood biochemistry test
-blood tubes
-centrifuge machine
-automated biochemsitry machine (test for organ funtion)
- glucometer
