Chapter 2 MEASUREMENT
2-5-1 Overview of calibration
Calibration is necessary to maintain measurement accuracy.
Calibration reduces unfavorable effects of reagent pack that changes
with time, eliminates gaps among lots or facilities, and maintains
measurement accuracy to a certain level.
Basically, calibration should be performed using the SPOTCHEM
Calibrator Kit for each type of Reagent Strips, but it requires a lot of time
to do so for all types of Reagent Strips.
To eliminate such inconvenience, this analyzer is designed to be able to
perform calibration for different Reagent Strips by inserting magnetic
cards (Reagent Card) storing the lot information of each reagent strip.
There are 2 methods for calibration with SP-4430.
1
・
Calibration by magnetic card
2
・
Calibration by calibrator kit (using an exclusive calibrator lit)
1 calibration is performed by inserting a magnetic card (Reagent card)
attached to each reagent strip into the magnetic-card reader.
2 calibration is performed using an exclusive calibrator. This calibration
should be performed every 6 months, when the Reagent Lot is changed
or the service representative considers that calibration is necessary. The
SPOTCHEM Calibrator Hb Kit is to be used for Hb items. The
SPOTCHEM Calibrator Kit is to be used for other items’ calibration.
There are two ways of calibration available, one is “1-Point Calibration”
using either Low or High Calibrator Solution and the other is “2-Point
Calibration” using both of Low and High solution. Make sure to perform
calibration according to the calibration conditions of each measurement
item by referring to “3-3-2 Entering parameters”.
