Pro­fi­ci­en­cy Test for Inhibitors

 

Espe­cial­ly when it comes to such a sen­si­ti­ve tobic as the pre­sence of vete­ri­na­ry drug resi­du­es in milk and milk pro­ducts it is essen­ti­al for every labo­ra­to­ry to opti­mal­ly secu­re its own ana­ly­sis results. This is shown by the high num­ber of par­ti­ci­pants in the inhi­bi­tor pro­fi­ci­en­cy tests. The aim of this pro­fi­ci­en­cy test is to con­firm that your rou­ti­ne inhi­bo­tor test ana­ly­sis detects anti­bio­ti­ca resi­du­es in mil­kes com­mon­ly used inhi­bi­tors as peni­cil­lin G, clo­xa­cil­lin and ampi­cil­lin with rou­ti­ne inhi­bi­tor ana­ly­sis with MRL Level (maxi­mum resi­due accord­ing to Regu­la­ti­on (EU) No. 37/2010) be veri­fied by the par­ti­ci­pa­ting laboratory.

We car­ry out this Inhi­bi­tor Pro­fi­ci­en­cy Test with lyo­phi­li­zed sam­ples from UHT milk regu­lar­ly in the spring.

Mul­ti­pa­ra­me­ter Pro­fi­ci­en­cy Test Ingre­di­ens       MULTI-PT

 

Para­me­ters, sam­ple mate­ri­al and sam­ple ana­ly­sis:
For ana­ly­sis out of cow raw milk our MUL­TI-PT covers 19 dif­fe­rent para­me­ters and up to 10 dif­fe­rent con­cen­tra­ti­on levels for each par­amters (see table on page 3 and 4). For cream (cow milk) we offer 3 dif­fe­rent con­cen­tra­ti­on levels and 3 dif­fe­rent para­me­ters (see table 4).  Par­ti­ci­pa­ti­on in all para­me­ters is not obli­ga­to­ry, you have the pos­si­bi­li­ty to sign up only for the para­me­ter you inte­res­ted in. This allows you to opti­mi­se your par­ti­ci­pa­ti­on cos­ts. Depen­ding on the para­me­ters you par­ti­ci­pa­ting in, you will recei­ve a sam­ple set that con­sists up to 26 dif­fe­rent sam­ples for raw milk ana­ly­sis and 3 dif­fe­rent sam­ples for cream ana­ly­sis. All methods will be con­si­de­red, i.e. “refe­rence” and “alter­na­ti­ve” method. Each ana­ly­sis has to be per­for­med under repeata­bi­li­ty con­di­ti­ons. Sta­tis­ti­cal cal­cu­la­ti­on will be done by Quo­Da­ta GmbH. Sta­tis­ti­cal  ana­ly­sis will be per­for­med accord­ing to ISO 17043.
