lecture 21 automation Flashcards
what is osmometry
measures molality of body fluids, solutes carried in urine/plasma. freeze point depression
what is reflectance principles for urinalysis
uses reflectance to measure amount detected on test strip
what is enzyme immunoassay
detects antigen/antibody using enzyme chemiluminescent tags
what is impedance
channels designed to facilitate flow of single cells, resistance= pulse= cell
what is end point and chromogenic clot detection
measure patient coagulation pathway
what is blood culture instrumentation
bacteria growth in blood will consume labelled CO2. Co2 detected using flurophore (BACTEC)
what is MALDI-TOF
measures unique ratio of size to charge (M/Z ratio)
what is transfusion medicine automation machine
Provue
purpose of osmometers
monitor progression of diabetes and renal disease
what is chromogenic clot detection
complex hemostasis. coagulation fcgor cleaves synthetic substrate, chromophore released, colour change
what is electrochemical clot detection
as clot forms it completes electric circle. as clot gets bigger,balls moves less until it stops
