The present invention provides a stable control serum or plasma for tumor diagnosis, wherein the control contains the tumor markers relevant for the diagnosis of tumors. The serum or plasma has a reduced lipid content. The present invention also provides for a method of making the control.

Tumor marker control

Aqueous solutions containing buffers and electrolytes are adjusted to levels required for calibration of both blood gas analyzers and ion selective electrolyte analyzers. A control material, composed of similar matrix, is adjusted to three levels of blood gas and electrolyte conditions. These quality control materials are used to monitor blood gas/electrolyte laboratory instrumentation.

Method of making a blood gas/electrolyte control

The present invention relates to a biosynthetic cerebrospinal fluid control and method of use. Additionally, this invention relates to the isolation and purification of stable liquid human prealbumin, a component in the biosynthetic cerebrospinal fluid control.

Disclosed are cell-free, stable, aqueous blood gas controls containing a proteinaceous foaming agent. The addition of foaming agent to the blood gas control permits generation of a gas impermeable foam within the head space of a sealed ampule in which the control is packaged. Upon agitation of the ampule prior to opening, the foam thus generated effectively isolates the control fluid from the ambient environment, thereby maintaining the concentration of gases dissolved within the fluid at their assigned values.
