About the system
The cobas t 711 coagulation analyzer is a fully
automated, high throughput system for coagulation tests.
The analyzer is designed for a large array of quantitative
in vitro tests and can be operated 24 hours a day, 7 days a
week.
The analyzer consists of the following components:
Component Function
Analyzer unit Contains the incubators and photometers, used for making
measurements; also contains the cuvette handlers, which
move the cuvettes for pipetting, mixing, and measuring.
Control unit Controls the analyzer functions
Cuvette transport unit Transports the cuvettes from the cuvette reservoir to the
analyzer unit.
Fluid unit Manages the system fluids: Water, liquid waste, System
Cleaner, samples, and reagents.
Reagent storage Refrigerates and stores the reagent cassettes.
Sampling unit Includes the rack loading area slots for placing different types
of racks, and the sample balcony for handling rack trays. From
the slots and sample balcony, racks are moved to the barcode
reader for scanning and are then moved to the rack area.
Transfer unit Pipettes samples, reagents, and other fluids from their
containers into cuvettes for mixing so that measurements can
be performed.

20 About the measuring principle
About the measuring principle
The analyzer performs optical measurements for clotting
tests, chromogenic tests, and immunoturbidimetric tests.
The analyzer performs the following tasks:
• Sample and reagents are pipetted into a cuvette and
incubated to ensure that all reaction components are
at the correct temperature.
• The reaction is started by adding a start reagent.
• The photometer measures turbidity or color change
for the respective test.
Clotting test
Plasma is mixed with a reagent or reagents, resulting in
the formation of a fibrin clot that increases the turbidity of
the mixture. The clotting time is calculated based on the
change in turbidity.
Chromogenic test
Plasma is mixed with reagent containing a chromogenic
substrate for a specific enzyme. The activation of the
enzyme results in cleavage of the chromogenic substrate
and a product changing the color of the reaction mixture
is formed. This change of absorbance is measured and
calculated per unit of time.
Immunoturbidimetric test
Plasma is mixed with reagent containing latex particles
coated with antibodies for a specific analyte. The latex
particles form complexes with the analyte, resulting in a
change of turbidity of the reaction mixture. This change is
then measured.
