Lyphochek Diabetes Control is a lyophilized, human whole blood-based control that is used to monitor the clinical assay precision of hemoglobin fractions associated with diabetes, including Hemoglobins A1, A1C, F, Total Glycated Hemoglobin and Total Hemoglobin. The product is provided in lyophilized form for ease of storage and increased stability. 

The control is available in two significant levels. Multiple levels allow for monitoring of test system reliability. The independent Lyphochek Diabetes Control monitors HbA1c and Total Hemoglobin test procedures, and it has value assignment listings for over 30 methods, including HPLC, immunoassay and point-of-care methodologies.

Applications & Use

This product should be treated the same as patient specimens and used in accordance with the instructions accompanying the instrument, kit, or reagent.

Using a volumetric pipette or equivalent, reconstitute each vial with 0.5 mL of distilled or deionized water. Replace the stopper and allow this product to stand for approximately 5 to 10 minutes, and swirl occasionally. Before sampling, gently swirl the vial several times to ensure homogeneity.

The reconstituted control exhibits column elution profiles and temperature sensitivities comparable to those of patient whole blood samples. Hemoglobin A1C results for the control must be corrected for temperature as recommended by the reagent manufacturer to achieve the assigned values.

Frequently Asked Questions

After use, how long can the control product be left out before return to refrigerator?
Typically, if the product has been stored refrigerated, allow the product to reach room temperature (18°C to 25°C) before use (specific time limitations may apply, depending on the product). For optimal analyte stability, promptly return the product to the recommended storage temperature after each use.
What type of water should be used to reconstitute lyophilized control products?
Typically, distilled or deionized water is used. Please refer to the product insert (IFU) for product specific diluent and reconstitution instructions.
How long should the reconstituted control remain at room temperature prior to use?
Upon reconstitution, the stopper should be replaced and the product should be allowed to stand at room temperature for the time period indicated in the product insert (IFU). Prior to use, gently swirl the vial to ensure homogeneity. Refer to the procedure section of the product insert (IFU) for product-specific handling instructions.
How long should frozen liquid controls sit at room temperature in order to thaw?
Typically, the frozen product should be allowed to thaw at room temperature (18°C to 25°C) for the time indicated in the package insert or until completely thawed prior to use. The product vial should be swirled gently to ensure homogeneity prior to use. Refer to the procedure section of the product insert (IFU) for product-specific handling instruction.
What are the acceptable limits for room, refrigerator, and freezer temperature?
This information is stated in the product insert (IFU):
  • Room temperature: 18°C to 25°C
  • Refrigerator temperature: 2-8°C
  • Freezer temperature: -20°C to -70°C/-20°C to -50°C for 2.5 mL vial

Most frozen products recommend avoidance of frost-free freezers. There are exceptions, so refer to specific control insert.
