Serological Testing Separator Primary Sampling Tubes for Suitability of Frozen Serum Stored in Gel

Suitability of frozen serum stored in gel separator primary sampling tubes for serological testing.

The suitability of frozen serum after storage in primary sampling tubes with a gel separator for serological enzyme-linked immunosorbent assay testing (hepatitis B virus surface antigen [HBs Ag], anti-HBs Ag, anti-Toxoplasma gondii immunoglobulin G [IgG], anti-rubella virus IgG, anti-cytomegalovirus IgM, and anti-Epstein-Barr virus IgM) was evaluated for 375 samples. No difference was found amo...

A comparison of IgG anti-rubella activity in frozen serum stored in primary gel separation tubes or secondary tubes.

AIMS To determine the suitability of primary gel separation tubes for the storage of frozen sera intended for serological testing. METHODS Blood samples from 102 patients were collected into gel separation tubes. The sera from these samples were split between the primary gel separation tubes and conventional plastic storage tubes and frozen. A year later, the tubes were thawed and anti-rubell...

Iodinated contrast media interfere with gel barrier formation in plasma and serum separator tubes.

Effect of use of gel-barrier sampling tubes on determination of some antiepileptic drugs in serum.

We evaluated the effect on drug concentration of the duration of sample storage in three different tubes for blood collection: SST (Becton Dickinson), AutoSep (Terumo), and Microvette (Sarstedt), all of which contain an inert barrier (e.g., gel) for cleaner separation of serum from coagulum during centrifugation. With two of the tubes (SST and AutoSep) we examined samples taken from patients un...
