PRINCIPLE OF THE METHOD
The assay is based on agglutination reactions. These involve in vitro
aggregation of microscopic latex particles. This aggregation consists in
the specific reaction between antigen and antibodies. Antigens contained
in the sample bind with the antibodies coated on polystyrene latex
particles. The sample is mixed with a suspension containing antibodies
against the antigen bound to latex particles. If antigen is present in the
sample, it will react with the antibodies and form an aggregate. If no
antigen is present in the sample, the mixture will maintain its clear appearance.
CONTENTS
PARAMETERS
STORAGE AND STABILITY
Store at 2-8ºC.
Components are stable once opened until the expiry date marked in the
label if kept at the recommended storage temperature, well closed and if
contamination is prevented during their use.
On board stability: The reagents opened and stored in the refrigerated
compartment of the analyzer are stable for 30 days.
Do not freeze. Reagent deterioration: presence of particles (R1,R2)and
turbidity (R1).
SAMPLES
Use sample collection tube, following the instructions included in the
package.Store stool samples in collection tube during maximum 7 days
at 2-8ºC. For longer periods freeze the samples at -20ºC and thaw
prior to use.
NOTES
The clinical diagnosis should not be based on a single test result; the
complete medical history of the patient should be taken into
consideration.
