Assay Type
Control Plasmas and Calibrators
Description
Three levels of control plasmas derived from pooled human plasma
Intended Use
PlasmaCon N is a human lyophilized plasma control intended for use as a normal control with citrated plasma to monitor the performance of the Prothrombin Time (PT) and Activated Partial Thromboplastin Time (APTT) tests.

PlasmaCon L-1 is a human lyophilized plasma control intended for use as a mid-level abnormal control with citrated plasma to monitor the performance of the Prothrombin Time (PT) and Activated Partial Thromboplastin Time (APTT) tests.

PlasmaCon L-2 is a human lyophilized plasma control intended for use as a high level abnormal control with citrated plasma to monitor the performance of the Prothrombin Time (PT) and Activated Partial Thromboplastin Time (APTT) tests.

Uses
PlasmaCon controls are used as normal plasma and abnormal plasmas in an internal QC program.

Principle of the Test
All laboratory assays require internal quality control (QC) as a component of the laboratory’s Quality Assurance program. Control ranges are determined with each lot change of reagent, with each lot change of control, and with major service of the instrument. Thereafter controls are run according to the requirements of the Clinical Laboratory Improvement Amendments. Currently the minimum requirement is two levels of control run every 24 hours; laboratories should consult the current CLIA or ISO regulations and the reagent manufacturers’ recommendations when they design their internal QC programs.

PlasmaCon control plasmas provide the laboratory a two or three level set of controls for its daily QC of its PT and APTT reagents. PlasmaCon control plasmas are manufactured from pooled plasma to which buffers and stabilizers have been added. PlasmaCon N is manufactured from pooled normal plasma. PlasmaCon L1 and L2 are manufactured from pooled plasma that is selectively depleted of various clotting factors, creating abnormal plasmas of different severities.
