Más eol an modh scagthástála nó má tá coinne leis go mbeidh an modh scagthástála infheidhme maidir le tráchtearraí eile, fíorófar bailíocht na dtráchtearraí eile sin.
If the screening method is known or expected to be applicable to other commodities, the validity to these other commodities shall be verified.
Más eol an modh scagthástála nó má tá coinne leis go mbeidh an modh scagthástála infheidhme maidir le tráchtearraí eile, fíorófar bailíocht na dtráchtearraí eile sin.
If the screening method is known or expected to be applicable to other commodities, the validity to these other commodities shall be verified.
ciallaíonn ‘modh scagthástála’ an modh a úsáidtear chun na samplaí sin, lena ngabhann leibhéil míceatocsainí a sháraíonn an spriocthiúchan scagthástála (STC), a roghnú le deimhneacht faoi leith.
‘screening method’ means the method used for selection of those samples with levels of mycotoxins that exceed the screening target concentration (STC), with a given certainty.
ciallaíonn ‘scoithluach’ an fhreagairt, comhartha nó tiúchan, a fhaightear leis an modh scagthástála, a n-aicmítear sampla mar shampla ‘faoi amhras’ nuair a bhíonn sé os a chionn.
‘cut-off value’ means the response, signal, or concentration, obtained with the screening method, above which the sample is classified as ‘suspect’.
I gcás modh scagthástála bithanailíseach, ní ceanglas fíor-riachtanach é teorainn chainníochtaithe (LOQ) a bhunú ach cruthófar leis an modh gur féidir idirdhealú a dhéanamh idir an bánchinneadh agus an scoithluach leis.
For a bioanalytical screening method, the establishment of the limit of quantification (LOQ) is not an indispensable requirement but the method shall prove that it can differentiate between the blank and the cut-off value.
Is gá fíorú feidhmíochta a dhéanamh ar an modh scagthástála le linn gnáthanailíse, trí rialú cáilíochta anailíse agus bailíochtú leanúnach modha.
Performance verification of the screening method is required during routine analysis, by analytical quality control and ongoing method validation.
Is éard a dhéantar i bprionsabal le modh scagthástála sampla a aicmiú mar shampla comhlíontach nó mar shampla a bhfuil amhras ann go bhfuil sé neamhchomhlíontach.
A screening method in principle classifies a sample as compliant or suspected to be non-compliant.
ciallaíonn ‘sampla cóimheasa diúltach’ sampla ar eol go bhfuil sé saor ón míceatocsain a bhfuil scagthástáil le déanamh air lena haghaidh, mar gheall ar chinntiúchán roimhe sin le modh deimhniúcháin lenar ghabh íogaireacht leordhóthanach nó le modh eile nó, i gcás nach féidir sampla den sórt sin a fháil, ábhar lena ngabhann an leibhéal is ísle is féidir a fháil a fhad gur féidir teacht ar an gconclúid, leis an leibhéal sin, go bhfuil an modh scagthástála oiriúnach don fheidhm sin;
‘negative control (blank matrix) sample’ means a sample known to be free of the mycotoxin to be screened for, by previous determination using a confirmatory method of sufficient sensitivity or by other method or, where such sample cannot be obtained, material with the lowest obtainable level as long as the level allows the conclusion that the screening method is fit for that purpose;
