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

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

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...

Corrigendum to “Biomarkers for diagnosis of pediatric acute neuropsychiatric syndrome (PANS) – Sensitivity and specificity of the Cunningham panel” [J. Neuroimmunol. 312. (2017) 31–37]

We have been informed that Moleculera Labs recommend Red Top glass tubes when collecting blood for the Cunningham panel. In our study (Hesselmark and Bejerot, 2017) we have used serum sampling tubes (BD Vacutainer® SSTTM II Advance tubes, Gold Top) but erroneously reported sampling in “serum sampling tube (BD Vacutainer, yellow top)” (Section 2.6 in our paper). The use of another blood collecti...

Abnormal gel flotation in a patient with apperant pneumonia diagnosis: a case report

INTRODUCTION Serum blood collection tubes with separator gel are widely used by many laboratories for chemistry analyses. We describe a case of a primary blood collection tube filled with blood sample and a floating separator gel. MATERIALS AND METHODS The blood sample was collected from a 51 years old female in intensive care unit with the diagnosis of pneumonia into a BD Vacutainer SST tube...

Stability studies of common biochemical analytes in serum separator tubes with or without gel barrier subjected to various storage conditions

INTRODUCTION The collected and shipped blood samples are exposed to a various extra-analytical factors prior to analysis. The aim of the study was to determine the stability of analytes in serum gel tubes and plain tubes exposed to a range of storage temperatures and times after centrifugation. MATERIALS AND METHODS Fifteen healthy volunteers were recruited and venous blood was collected into...
