Samples were collected in BD Serum Separator tubes
, allowed to clot for 30 min, and then centrifuged for 10 min at approximately 1200g.
If facilities separate serum from cells within two hours, either by pouring the serum/plasma into transfer tubes or by using gel-type serum separator tubes
, they have successfully complied with the standards.
Bruns (10) also questioned whether fluoride-containing tubes are still needed for blood glucose testing in his editorial support of the study by Fernandez et al, (11) which reported no difference in glucose values for blood specimens collected in serum separator tubes
(SST) and NaF tubes that were separated within two hours of collection.
Each blood sample drawn was divided into two tubes: (1) one-half was collected into EDTA tubes for full blood count (FBC) analysis; and (2) the other half into Serum Separator Tubes
for muscle injury markers.
The blood was placed into serum separator tubes
Blood samples were collected in serum separator tubes
(Becton-Dickenson, Franklin Lakes, NJ), centrifuged for 15 min at 10,000 rpm, and shipped on ice to the CDC for testing.
In less than 9 months and with barely any disruption of production, the system was handling blood serum separator tubes
24 hours a day, 5 days a week.
Blood was transferred to serum separator tubes
and was refrigerated until centrifugation.
According to BD data on file, clinical testing on its Vacutainer RST tubes has demonstrated a 59% relative reduction in hemolysis and a 59% relative decrease in fibrin strands compared to standard serum separator tubes
Blood samples from 10 normal donors were collected into EDTA plasma preparation, lithium heparin plasma separator, and serum separator tubes
and evaluated for stability at room temperature, 2-8 [degrees]C and after multiple freeze-thaw cycles after centrifugation and removal of the supernatant.
Venous blood was collected in plastic serum separator tubes
It has been reported (3) that collecting specimens in serum separator tubes
increases CRP values measured by the VITROS CRP slide; however, the differences we saw were much greater than those attributed to serum separator tubes
