Maine Standards Company LLC has released Validate anemia, a calibration verification and linearity test kit that contains ferritin, folate, and vitamin B12 in a human-serum base matrix. Prepared using the “equal delta” method recommended for linearity testing by the Clinical and Laboratory Standards Institute, the kit contains liquid, ready-to-use linearity testing material. Lab professionals can simply add the product from the dropper bottle directly into a sample cup and run as a patient sample in duplicate or triplicate. The kit seeks to maximize reportable range while minimizing manual dilutions. It stores from -10°C to -25°C. For more information, visit Maine Standards Company.
