Esame fisico, chimico e morfologico delle urine: raccomandazioni per la fase postanalitica del Gruppo Interdisciplinare Laboratorio e Clinica Apparato Urinario (GIAU)
Physical, chemical and morphological urine examination: recommendations for the postanalytical phase from the Interdisciplinary Urinalysis Group (GIAU)
<p>This document of the Interdisciplinary Urinalysis Group (GIAU) is aimed to provide recommendations on how to improve and standardize the postanalytical approach to physical, chemical and morphological urine examination (ECMU). The main tool to emphasize the value of the ECMU is the development of a laboratory report suitable for the clinical needs. As a consequence, these recommendations are mainly related to the structure and content of the report. They include: the layout, the parameters to be included, the measurement units, the reference values, the inclusion of interpretative comments. Really, an important section of the report is dedicated to the interpretative comments: these are a real add-on value and are tailored on the type of laboratory performing the analysis (general or with a specific section dedicated to the urine examination). The different levels of the laboratory competence determine the category of possible comments. The basic one concerns comments that evaluate the non-conformity of the sample (i.e. presence of urethral, seminal, vaginal, faecal contamination; too concentrated/too diluted samples). The second level of comments is dedicated mainly to the reporting of the discrepancies between the biochemical analysis and the microscopy examination (i.e. presence of haemoglobin and no erythrocyte detection; presence of leucocyte esterase and no leucocyte detection). The third level requires a specific competence of the pathologist together with a strict collaboration with the clinic; these comments are elaborated on the basis of a specific clinical request. The detection of the &ldquo;decoy cells&rdquo; in immunosuppressed solid organ transplant recipients, that are typical of a poliomavirus infection, is a good example of the third level of interpretative comments. A final section of the document is dedicated to the opportunity to implement and adopt specific programs of external evaluation of the urinary sediment.<br />After the issuing of the recommendations dedicated to pre-analytical and analytical phases, this GIAU document gives suggestions for the standardisation and harmonisation of post-analytical phase in the attempt to emphasize the diagnostic importance of ECMU.</p>

Esame fisico, chimico e morfologico delle urine: proposta di linee guida per la fase analitica del Gruppo Intersocietario Analisi delle Urine (GIAU)
Physical, chemical and morphological urine examination: proposed guidelines for the analytical phase by the Intersociety Urinalysis Group
<p>With these guidelines, the Intersociety Urinalysis Group (GIAU) aims to stimulate the following aspects: a) improvement and standardization of the analytical approach to physical, chemical and morphological urine examination (ECMU); b) to emphasize the value added to ECMU by automated analyzers for the study of the morphology of the corpuscular fraction urine; c) improvement of the chemical analysis of urine with particular regard to the reconsideration of the diagnostic significance of parameters that are traditionally evaluated in dipstick analysis, together with an increasing awareness of the limits of sensitivity and specificity of this analytical method; d) to increase the awareness of the importance of professional skills in the field of urinary morphology and of the relationships with clinicians; e) implementation of a policy for the evaluation of the analytical quality by using, in addition to traditional IQC and EQA, a program for the evaluation of morphological competence; f) to stimulate the diagnostic industry to focus research efforts and development methodology and instrumental catering to the needs of clinical diagnosis. The hope is to revalue the enormous diagnostic potential of ECMU, by implementing an urinalysis based on personalized diagnostic needs.</p>

Automated screening of bacterial meningitis by cytofluorimetric analysis of cerebrospinal fluid: preliminary results
<p>This study was planned to assess the diagnostic performance of the automated urine particle analyzer Sysmex UF-1000i for the rapid screening of cerebrospinal fluid (CSF) in patients with suspected meningitis. Cytometric analyses&nbsp;with either optical microscopy (OM) or UF-1000i, along with assessment of glucose and protein in CSF, were performed&nbsp;on 101 consecutive CSF of patients with suspected meningitis. In 50 out of 101 samples, cultural analysis was also&nbsp;performed with different culture media. Four different diagnostic combination were developed, with different mix of the&nbsp;tested parameters. A high correlation was found between OM and UF-1000i (r=0.99; mean bias, -4.9/&mu;L). The&nbsp;diagnostic agreement was 0.90 in adults and 0.97 in children. The diagnostic agreement between CSF culture and&nbsp;bacterial count by UF-1000i was 0.98, with 1.00 sensitivity and 0.98 specificity. Results showed that the diagnostic&nbsp;combination based on CSF glucose and total proteins, cytometric analysis (leukocyte count &plusmn; neutrophilia) and&nbsp;bacterial count on UF1000i exhibited the best performance when compared with microbiological examination (area&nbsp;under ROC curve, 1.00). In conclusion, the results of this study show that the combination of two rapid clinical&nbsp;chemistry tests such as glucose and total proteins with UF-1000i analysis could represent a valid approach for&nbsp;supporting more complex analyses or even for replacing OM and CSF culture during stat examination and to achieve&nbsp;a quick detection of central nervous system infections.</p>
