Indications for Use
Control Plasma N is an assayed control for use in monitoring the performance of the following parameters in the normal range: 1. Prothrombin time (PT) 2. Activated partial thromboplastin time (APTT) 3. Thrombin time (TT) 4. Batroxobin time 5. Fibrinogen 6. Coagulation factors II, V, VII, VIII, VWF, IX, X, XI, XII 7. Inhibitors: Antithrombin III, protein C, protein S, a2 -antiplasmin 8. Plasminogen 9. Lupus anticoagulants. Control Plasma P is an assayed control for use in monitoring the performance of the following parameters in the pathological range: 1. Prothrombin time (PT) 2. Activated partial thromboplastin time (aPTT) 3. Fibrinogen (Clauss method) 4. Coagulation factors II, V, VII, VIII, VWF, IX, X, XI, XII 5. Inhibitors: Antithrombin III, protein C, protein S, a2 -antiplasmin 6. Plasminogen.
Device Story
Control Plasma N and P are lyophilized, human-plasma-derived controls used in clinical laboratories to monitor the performance of coagulation assays. Control Plasma N is pooled human plasma stabilized with HEPES buffer for normal range monitoring; Control Plasma P is pooled human plasma adjusted to defined factor concentrations and stabilized with HEPES for pathological range monitoring. These controls are used by laboratory technicians to verify the accuracy and precision of coagulation testing systems. By comparing observed results against the assayed values provided for the controls, clinicians ensure the reliability of patient test results for parameters including PT, aPTT, fibrinogen, and various coagulation factors. This quality control process helps maintain the integrity of clinical decision-making regarding patient coagulation status.
Clinical Evidence
No clinical data. Bench testing only. Precision/reproducibility evaluated using retrospective data from 68 lots (Control Plasma N) and 54 lots (Control Plasma P). Control Plasma N precision: 2.1–4.5% CV. Control Plasma P precision: 3.0–8.1% CV.
Technological Characteristics
Pooled human plasma; HEPES buffer stabilizer; lyophilized form; siliconized vials. Compatible with mechanical and photo-optical coagulation instrumentation. Traceable to WHO reference preparations and in-house standards.
Indications for Use
Indicated for use as an assayed control to monitor the performance of coagulation assays in normal (Control Plasma N) and pathological (Control Plasma P) ranges for patients undergoing coagulation testing.
Regulatory Classification
Identification
A multipurpose system for in vitro coagulation studies is a device consisting of one automated or semiautomated instrument and its associated reagents and controls. The system is used to perform a series of coagulation studies and coagulation factor assays.
Special Controls
*Classification.* Class II (special controls). A control intended for use with a multipurpose system for in vitro coagulation studies is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 864.9.
