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.
