Samsung LABGEO
PA20
Introduction
Ŷ Introduction
The Samsung LABGEO
PA20
is a fully integrated photometric device that can perform both
clinical chemistry analyses and immunoassays simultaneously. Innovative laser-actuated
microvalves together with the centrifugal microuidics makes the total process of plasma
separation, metering, mixing, incubation, washing, and detection fully automatic.
A lithium-heparinized whole blood, plasma, or serum sample of 450uL is applied directly
to a disposable reagent disc and the disc is inserted into the analyzer by an operator. Each
reagent disc is self-contained clear plastic with diameter of 12 cm and thickness of 0.8 cm,
which consists of dierent kinds of reagents and buers.
The entire process is activated once the operator touches the “Run” button on the display.
The ‘self-test’ function is initiated, whereby the main power, main motor, laser motor,
temperature IC, photometer, laser, heater and barcode reader are checked. The ‘self-test’
function is conducted automatically before each test or control run. This built-in self
testing function minimizes maintenance costs. After inserting a reagent disc into a tray,
the analyzer automatically detects the disc type and identies the clinical chemistry and
immunoassay tests before performing the assays. The analysis is completed in about 12 to
25 minutes depending on the disc type.
The results are displayed on the LCD screen along with the reference ranges, can be printed
out by an internal thermal printer, and can be transferred to a laboratory information
system and electronic medical record systems (LIS/EMR) via an Ethernet and wireless LAN
ports. Data storage is up to 5,000 patient results and 3,000 control results in the instrument.
The system provides user-friendly and easy interface for analysis that minimizes user
manipulation. Handy compact design (246(W) x 375(D) x 289(H) mm
3
) allows maximized
space utilization and the light weight (~ 9.2 kg) provides portability.
Compared to conventional blood analyses done in clinical laboratories, the analyzer system
is suitable for point-of-care applications because it requires a smaller amount of blood
takes less time, and does not require specially trained operators, or expensive instruments
to run biochemical assays and immunoassays separately.
