followed and the Instrument Operating Manual must be
consulted.
The use of the kit is only possible with an updated
version of software. Make sure that the software
installed in the instrument corresponds or has a
Release (Rel.) subsequent to the one reported in the
table
published
(http://www.diesse.it/en/Support/Download/strumento:39/)
5.
Check that the Chorus TRIO instrument is set up correctly
(see Operating Manual).
6.
Do not alter the bar code placed on the handle of the device
in order to allow correct reading by the instrument.
7.
Avoid using self-defrosting freezers for the storage of the
samples.
8.
Defective barcodes can be inserted manually in the
instrument (see Operating Manual).
9.
Do not expose the devices to strong light or to hypochlorite
vapors during storage and use.
10. The use of strongly hemolyzed, lipemic, icteric samples, of
serum not completely coagulated or of samples presenting
microbial contamination may all constitute sources of error.
11. Do not use the device after the expiry date.
12. Make sure that the instrument is connected to the
Washing Buffer Autoimmunity (Ref. 86004).

STORAGE AND STABILITY OF REAGENTS
Reagents must be stored at 2/8°C. In the case of storage at
an incorrect temperature the calibration must be repeated
and the run validated using the control serum (see section
9, Test validation).
The expiry date is printed on each component and on the kit
label.
Reagents have a limited stability after opening:

SPECIMEN COLLECTION AND STORAGE
The sample is composed of serum collected in the normal
manner from the vein and handled with all precautions dictated
by good laboratory practice.
Possible consequences, in case of use of other biological liquids,
are not known.
The fresh serum may be stored for 2 days at 2/8°C, or frozen for
longer periods at –20°C.
The sample cannot be repeatedly thawed.
Do not keep the samples in auto-defrosting freezers. Defrosted
samples must be shaken carefully before use.
Heat-inactivation can rise to erroneous results.
The quality of the sample can be seriously affected by microbial
contamination which leads to erroneous results.

ASSAY PROCEDURE
1.
Open the package (on the side containing the pressure-
closure), remove the number of devices required and seal
the rest in the bag after expelling the air.
2.
Check the state of the device according to the indications
reported in chapter 4, Analytical Precautions.
3.
Dispense 150 µl of undiluted test serum in well no. 1 of each
device; at each change of batch, use a device for the
calibrator.
