A sample distribution programme for erythropoietin

INTERNATIONAL JOURNAL OF LABORATORY HEMATOLOGY, Issue 4 2006
J. T. MARSDEN
Summary A survey was sent to laboratories participating in the United Kingdom External Quality Assessment Service (UKNEQAS) Haematinics Scheme about the measurement of serum erythropoietin (EPO). Six laboratories, from a total of 120 that returned the survey, were measuring serum EPO concentrations by commercially available immunoassays on site in the United Kingdom. The workload of the laboratories varied from up to 100 specimens per month to more than 100 specimens analysed per week. All laboratories included control material in the assays and none of the laboratories was participating in an external quality assessment scheme for serum EPO. Four laboratories agreed to take part in the first sample distribution programme, with five and six laboratories participating in distributions 2 and 3 respectively. The results from eight kits were compared from the three distributions over a 2-year period. The serum EPO concentrations for the methods showed some variation across the range of 2.9,200 U/l when the serum EPO concentrations for each method were compared with the whole method mean. The results from this scheme have identified a role for an external quality assessment scheme for serum EPO measurements. [source]

Variation in GH and IGF-I assays limits the applicability of international consensus criteria to local practice

CLINICAL ENDOCRINOLOGY, Issue 1 2007
A. Pokrajac
Summary Background, There is increasing reliance on consensus criteria for decision making. Recent criteria state that acromegaly is excluded by a nadir GH during an oral glucose tolerance test (OGTT) of < 1 µg/l and a normal level of IGF-I. Objective, To study GH and IGF-I assay performance close to cut-off values for active acromegaly. Design and methods, Two serum samples known to give borderline results were sent to all centres participating in the UK National External Quality Assessment Service (NEQAS). Sample A was assigned to be a nadir during an OGTT and sent for GH assessment to 104 centres. Sample B, with a clinical scenario, was sent to 23 centres that measure IGF-I, and these centres were asked to measure IGF-I, interpret the result and provide the source of their reference ranges (RRs). Results, For sample A, the median GH was 2·6 mU/l (range 1·04,3·5 mU/l). Applying a conversion factor (CF) of 2·0 (1 µg/l = 2 mU/l), the most negatively biased method classified 10% of the values consistent with acromegaly, while the most positively biased method classified all values as consistent with the diagnosis. Applying a CF of 3·0 (1 µg/l = 3 mU/l), only 11% of results were consistent with acromegaly. For sample B, the median IGF-I was 50·8 nmol/l (range 24·3,60·9 nmol/l). All centres used age-related RRs. There was a 50% variation in the upper limit of the RRs between centres. Overall, 30% of the IGF-I results were against the diagnosis. There was little agreement in the RRs quoted by centres using the same method. Conclusion, Variability in assay performance, coupled with use of inappropriate CFs and RRs, undermines the applicability of international consensus criteria to local practice. [source]


Assessment in a specialist referred family centre: outcomes for children

CHILDREN & SOCIETY, Issue 5 2001
Andrew Pithouse
Relatively little is known about the outcomes of assessment as an information gathering mechanism as well as a therapeutic encounter in which service users explore and share their problems. Assessment in child welfare is now a highly topical issue given the new assessment framework recently introduced to England and which is currently a matter of consultation in Wales. In contributing to a long running debate over ,what works' in child protection assessment and intervention, a United Kingdom national voluntary child care agency commissioned the authors to undertake a three year outcomes study of a child and family assessment service provided by their specialist referred family centre in South Wales. The paper sets out selected findings that reveal an assessment regimen which encouraged partnership, enjoyed a comparatively high level of engagement particularly from male parents/carers, and was perceived by adult users as positive. It promoted clear decision making about the placement of children. Also, children involved in these assessments appeared to be exposed to low risk of re-abuse compared to other relevant studies.
