Flashcards in lecture 21 automation Deck (11):
1

what is osmometry

measures molality of body fluids, solutes carried in urine/plasma. freeze point depression

2

what is reflectance principles for urinalysis

uses reflectance to measure amount detected on test strip

3

what is enzyme immunoassay

detects antigen/antibody using enzyme chemiluminescent tags

4

what is impedance

channels designed to facilitate flow of single cells, resistance= pulse= cell

5

what is end point and chromogenic clot detection

measure patient coagulation pathway

6

what is blood culture instrumentation

bacteria growth in blood will consume labelled CO2. Co2 detected using flurophore (BACTEC)

7

what is MALDI-TOF

measures unique ratio of size to charge (M/Z ratio)

8

what is transfusion medicine automation machine

Provue

9

purpose of osmometers

monitor progression of diabetes and renal disease

10

what is chromogenic clot detection

complex hemostasis. coagulation fcgor cleaves synthetic substrate, chromophore released, colour change

11

what is electrochemical clot detection

as clot forms it completes electric circle. as clot gets bigger,balls moves less until it stops
