multiCare In CHOLESTEROL Control Solutions are used to check the accuracy of
Cholesterol system. The solutions contain a known quantity of Cholesterol which reacts with
the components of the Reagent Strip
Use: The Cholesterol values range of each control solution is shown on the label of the
Reagent Strips pack. The measuring procedure is very similar to that of whole blood
determinations. In case you suspect the correct functioning of the instrument or the Reagent
Strips, do the checking at least once with each Control Solution. If possible, use the solution
which Cholesterol value lies nearest to the one you would like to check. Checking is
recommended each time you open a new pack of Reagent Strips. The obtained results
should lie in the range of values indicated on the strips packs. multiCare In
CHOLESTEROL Control Solutions can also be used to learn and practise better the auto-
testing procedure, therefore to verify the User’s capability. A correct use of the system is
confirmed if the results of repeated measurements lie in the expected range
Composition: multiCare In CHOLESTEROL Control Solutions contain Cholesterol, at
different concentrations, in an aqueous solution. Other ingredients (and their approximate
concentrations) are indicated below:
Sodium Benzoate 0.2%
Synthetic Hydrophylic Polymer 12.5%
Principle of the method: The cholesterol content in MultiCare In TRYGLICERIDES
Control Solutions reacts with Cholesterol esterase/ Cholesterol Oxidase / Peroxidase/
Cromogen. The intensity the colour develops from the reaction is proportional to the
concentration of Cholesterol in the solution. MultiCare In CHOLESTEROL Control
Solutions can give different results if used with other Cholesterol determination systems.
The solutions are transparent.
Storage and Stability: multiCare In CHOLESTEROL Control Solutions should be
stored at room temperature (15-30°C), even after a dropper has been opened. At such
temperatures, a closed dropper is stable until the expiry date indicated on the label while an
open one must be used within 90 days. Write the opening date on the label and discard the
solution after 90 days. Dry the dropper’s tip after each use and close it well.
Procedure: your multiCare In CHOLESTEROL Control Solutions Kit is composed of :
two droppers (level 1 or level 2) and a data chip. The number of possible test is 125 per vial
Requisite accessories: a) multiCare In instrument and Manual
b) multiCare In CHOLESTEROL Reagent Strips
Execution: open the control solution box and take data chip you find inside ,insert it in the
instrument in use. Attention: In the display will appear the number 000. If appears another
number you are using a wrong chip.
Insert the reagent strip you want control and proceed in the same way as in Blood
Cholesterol determination using a drop of control solution instead of a blood drop. For more
details, please refer to the Instrument’s Manual. Invert the dropper 4 or 5 times before use
it. The result will appear in the instrument after 45 seconds.
Accurate results are obtained if the checking is executed correctly. Please follow the hints
below:
Avoid the formation of air bubbles when dispensing a drop; remove bubbles eventually
by a tissue before applying the drop
Apply a single drop once on the centre of the reactive area of the strip
Do not draw the drop back into the dropper once it has come in contact with the reactive
area of the strip
Do not let the dropper tip come in contact with the reactive area of the strip, otherwise
the Control Solution in the dropper can be contaminated by the strip reagents
Precautions:
1. The Control Solutions are only for diagnostic in vitro use
2. Use this product as has been supplied; do not add other substances or dilute it,
otherwise its diagnostic use will be compromised
3. Do not ingest or inject the Control Solutions
4. Use data chip you find inside the control solution kit. The number in the display must
be 000. Do not use data chip insert in the strip’s box.
Expected results: at room temperature multiCare In CHOLESTEROL Control Solutions
give results that are largely included (95%) in the Concentration Range indicated on the
Reagent Strips Vial.
In case your results are out of the expected range, possible causes are:
Incorrect test execution: read carefully the instructions in the instrument’s manual.
Control Solution is contaminated or expired. Replace with a new Control Solution or use
another one at a different concentration, if available.
Working Temperature is out of the recommended range above.
Reagent Strips are contaminated or expired.
The instrument isn’t clean how recommended in multiCare In Instrumental Manual
Data chip used is wrong.
If you still do not obtain satisfactory results:
Do not use the system for Cholesterol determinations
Contact the nearest multiCare In CHOLESTEROL sales’ office before still use the
instrument .
