The K-ASSAY ®   ASO/RF/CRP Control is intended to be used as a consistent test sample of known concentrations for monitoring the K-ASSAY ®
Anti-Streptolysin O (ASO),
Rheumatoid Factor (RF),
C-Reactive Protein (CRP),
and wide range CRP
immunoturbidimetric assays.

 1.  Carefully and slowly remove rubber stopper and let air enter vacuum-sealed bottle.

 2.  Carefully add exactly 2 mL purified water (at room temperature) to bottle.   DO NOT MIX.

 3.  Replace rubber stopper.

 4.  Let bottle sit at room temperature for 10 minutes.

 5.  Mix by slowly swirling bottle numerous times.  DO NOT SHAKE or induce foaming.

 6.  Continue to mix until all contents have dissolved completely.

 7.  Before each subsequent use, be sure to mix bottle by slowly swirling.

Store lyophilized and reconstituted controls at 2-8°C.  Return all controls to 2-8°C promptly after use.  Unopened controls can be used for one year from the date of manufacturing as indicated by the expiration date on the package and bottle labels.

Reconstituted controls can be used for 2 weeks if stored at 2-8°C.

Reconstituted controls can also be frozen immediately after reconstitution at -20°C for 2 months and then thawed ONE TIME ONLY.

The following values are given as an example.  The expected values for the K-ASSAY ®   ASO/RF/CRP Control are continually being revised through ongoing quality assurance.   As a result, the expected values may change from lot to lot.  Please refer to the package insert and/or vial labels for each lot for the expected values.
