ImmunoCAP® ISAC and Microtest for multiplex allergen testing in people with difficult to manage allergic disease: a systematic review and cost analysis. A combination of innovative biochip technology with cutting edge research in molecular allergology has resulted in ImmunoCAP® ISAC – the most advanced in. The immuno-solid phase allergen chip (ISAC) test (Thermo Fisher ImmunoCAP ISAC) is a microarray assay system designed to assay specific.

However, when ISAC was used to measure the same component as single IgE testing or to measure multiple components homologous proteinswith a positive test defined as any component positive, it appeared that equivalent sensitivities could be achieved without corresponding loss of specificity. Excluded studies One hundred and forty-eight full-text articles were retrieved: The following key conference proceedings, were identified in consultation with clinical experts, and were screened for the last 5 years where available:.
None of these studies reported test accuracy data. A systematic review was conducted to summarise the evidence on the clinical effectiveness and cost-effectiveness of ImmunoCAP ISAC and Microtest for multiplex allergen testing in people with allergic disease.

Data were extracted on the following: Therefore, the assessment aimed to inform research decisions and support future model-based economic evaluations. Remind me later Don’t remind me again.
Dec 22 reply retweet favorite 1 week ago. Lavender EDTA or green sodium or lithium heparin. The results of the risk-of-bias assessments are summarised and presented in tables and graphs in the results of the systematic review see Study quality and are presented in full, by study, in Appendix 4. Results Clinical effectiveness A total of records were identified from searching and screened for inclusion.
Common conditions under which a specimen will be rejected. If you have any further questions, needa consultation, treatment, or if any problems are identified throughout this testing process, we would be happy to book you an appointment to meet with one of our specialists.
A speculative analysis indicated that multiplex allergen testing would have to result in a substantial reduction of the proportions of patients receiving single IgE testing and food challenge tests in order to be cost-saving in the short term.
Please proceed to bank transfer payment of the invoice that you will receive by e-mail after you send your questionnaire.
ISAC Test: 112 Allergy Tests in one tiny blood sample!
Details of studies excluded at the full paper screening stage are presented in Appendix 3. Specimen Preparation Transfer 0. Additional searching was immunovap for grey literature, three trial registries and seven conference proceedings.
This study 36 included only nine participants who received a total of 31 courses of SIT no details of diagnosis were reported. Seven studies investigated changes to treatment or management outcomes. See Stability for additional info.
An approved NPL form must accompany specimen. However, because the review identified a small number of studies with between-study variations in participant characteristics allergy historymultiplex allergen testing methods, allergens tested for, standard care comparators, and outcomes assessed, we did not consider meta-analyses to be appropriate and have provided a structured narrative synthesis.
Change to diagnostic classification Two studies investigated the effect on diagnostic classification of adding ImmunoCAP ISAC testing to the standard diagnostic work-up of people with allergic disease.
No studies were identified of people with difficult to manage allergic disease in the UK. If you live immuocap a distance from London, or for any reason cannot attend a face-to face appointment, please start with filling in an ISAC allergy symptoms questionnaire, which will be reviewed by one of our allergy consultants.

Conclusions No recommendations for service provision can be made based on the analyses included in this report. Certain tests have specimen requirements that differ for specimens shipped from New York state. Fifteen studies were included in the review. Assessment of cost-effectiveness Four economic analyses and 14 health-related quality of life studies were included in the literature review.
The relatively low sensitivities of individual ISAC components are likely to be indicative of the proportions of patients in whom each component is associated with the observed allergic response.

It is suggested that a consensus-based protocol for the use of multiplex allergen testing be developed. None of the studies was conducted in the UK, seven studies 41 — 4649 were European and one study 47 was unreported. The main potential sources of bias were in relation to participant selection and application of the index kmmunocap. Systematic review methods Results of the assessment of clinical effectiveness assessment.
Oxford University Press; Of the 15 included studies, four immunocqp funded by, 3846 or received reagents and consumables 39 or testing services 45 from, the manufacturer. In all but two cases, 5152 these studies reported no relevant outcomes. None of the included studies was classified as having a low risk of bias. For more information, visit our browser page. The sensitivities and specificities of the individual components ISAC 50 components were not reported.
One study 47 was reported only as a conference abstract. You will receive a report with interpretation of your results from one of our Allergy and Immunoccap consultants! The searches of bibliographic databases and conference abstracts identified references.
In general, individual ISAC components tended to have high specificity, but low sensitivity, relative to whole-allergen single IgE tests or SPT for the prediction of allergic response. A conceptual model structure was developed, literature on utility scores was reviewed, and cost analyses were performed to examine the short-term costs of various possible diagnostic pathways. The results of the quality assessment have been used for descriptive purposes to provide an evaluation of the overall quality of the included studies and to provide a transparent method of recommendation for design of any future studies.
To assess the effects on clinical outcomes e.
