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 (Becton Dickinson, NJ, USA) containing serum separator gel and conveyed to the core laboratory of Marmara University Hospital within 30 minutes from collection. Sample was immediately centrifuged at room temperature at 1500 × g for 10 minutes.

Results:

The analyses revealed a highly increased total protein concentration of 145 g/L (reference interval 64–83 g/L). The nephelometric analyses showed an elevated serum IgG concentration of 108 g/L (reference interval 6.5–16 g/L) and IgG lambda monoclonal band was determined by serum immunofixation electrophoresis.

Conclusion:

Limitation of the separator gel tubes in patients with a high plasma density and its possible effects on test results and laboratory costs should be remembered. The clinical diagnosis stated in the information system should also reveal known comorbid conditions besides the apparent admission reason. This information would avoid resampling, additional testing, and communication efforts with the clinicians.  相似文献   

Diversity and equality in academic publishing: the case of educational leadership     

Sefika Mertkan  Nihan Arsan  Gozde Inal Cavlan  Gulen Onurkan Aliusta 《Compare》2017,47(1):46-61

There have been ongoing criticisms of the field of educational leadership and management with respect to over-reliance on research from ‘Western’ contexts. However, evidence on the extent to which voices alternative to the dominant ‘Western’ discourse are represented in the international English-medium discourse of educational leadership and management is thin. Using a three-phase sequential mixed-methods approach, this paper explores knowledge production in the field by analysing the prevalence and impact of empirical articles published in four English-medium international journals. Additionally, the membership of editorial boards and editors is analysed to geographically locate key decision makers. Findings demonstrate that an exceptionally small set of core inner-circle Anglophone and non-inner-circle Anglophone settings enjoys disproportionate influence in the field. There is need for a knowledge base enriched with leadership and management practices from different sociocultural contexts and system structures with a multiplicity of voices to portray a more nuanced and balanced picture of leadership and management practices.  相似文献
