Lesezeit<\/em><\/p>\n<p>Standard-Humanserum vom Typ AB stammt von gesunden, negativ gescreenten Spendern. F\u00fcr viele Forschungs- und Diagnostikanwendungen ist das genau richtig. F\u00fcr IVD-Assayentwicklung, Biomarker-Validierung und Kreuzreaktivit\u00e4tstests brauchen Sie jedoch Serum, das den zu messenden Analyten oder pathologischen Zustand tats\u00e4chlich enth\u00e4lt \u2013 Disease-State-Serum.<\/p>\n<h2>Was ist Disease-State-Serum?<\/h2>\n<p>Disease-State-Serum ist Humanserum von Spendern mit einer definierten, best\u00e4tigten Erkrankung. Anders als Standardserum \u2013 das gescreent wird, um Infektionserreger und pathologische Marker auszuschlie\u00dfen \u2013 wird Disease-State-Serum gezielt von Spendern gewonnen, die f\u00fcr einen Zielanalyten positiv sind oder eine definierte Erkrankung haben. Es ist das Positivkontrollmaterial und die Pr\u00fcfmatrix f\u00fcr die Assayentwicklung.<\/p>\n<p>Disease-State-Serum ist kein Forschungswerkzeug zur Untersuchung der Erkrankung selbst \u2013 es ist ein <strong>Reagenz f\u00fcr Qualit\u00e4tskontrolle und Assayvalidierung<\/strong> f\u00fcr Entwickler diagnostischer Tests, Immunoassay-Hersteller und Biomarker-Forscher, die echte Positivproben ben\u00f6tigen.<\/p>\n<h2>Wichtige Kategorien von Disease-State-Serum<\/h2>\n<h3>Infektionsmarker \u2013 f\u00fcr die IVD-Assayentwicklung<\/h3>\n<table>\n<tr>\n<th>Erkrankung<\/th>\n<th>Anwendung<\/th>\n<th>Hinweise<\/th>\n<\/tr>\n<tr>\n<td>HIV-1\/2-positiv<\/td>\n<td>Entwicklung von Anti-HIV-Antik\u00f6rperassays, NAT-Validierung<\/td>\n<td>Ak-positiv; RNA-positiv (vir\u00e4misch) separat erh\u00e4ltlich<\/td>\n<\/tr>\n<tr>\n<td>HBsAg-positiv (HBV)<\/td>\n<td>Entwicklung von HBsAg-Immunoassays, Quantifizierung des Oberfl\u00e4chenantigens<\/td>\n<td>Verschiedene Genotypen verf\u00fcgbar; HBeAg-Status angegeben<\/td>\n<\/tr>\n<tr>\n<td>Anti-HCV-positiv<\/td>\n<td>Entwicklung von HCV-Antik\u00f6rperassays, Best\u00e4tigungstests<\/td>\n<td>Serokonversionspanels f\u00fcr Tests im diagnostischen Fenster verf\u00fcgbar<\/td>\n<\/tr>\n<tr>\n<td>HCV-RNA-positiv<\/td>\n<td>Entwicklung von NAT-Assays, Viruslastquantifizierung<\/td>\n<td>Genotypspezifische Panels verf\u00fcgbar<\/td>\n<\/tr>\n<tr>\n<td>Syphilis (T. pallidum) positiv<\/td>\n<td>Entwicklung treponemaler Antik\u00f6rperassays<\/td>\n<td>RPR\/VDRL-Titer angegeben<\/td>\n<\/tr>\n<tr>\n<td>HTLV-I\/II-positiv<\/td>\n<td>Entwicklung von Screeningassays f\u00fcr Blutbanken<\/td>\n<td>Selten \u2013 Verf\u00fcgbarkeit bitte anfragen<\/td>\n<\/tr>\n<\/table>\n<h3>Autoimmun- und Entz\u00fcndungserkrankungen<\/h3>\n<table>\n<tr>\n<th>Erkrankung<\/th>\n<th>Anwendung<\/th>\n<\/tr>\n<tr>\n<td>Rheumafaktor (RF) positiv<\/td>\n<td>Interferenzpr\u00fcfung in Immunoassays \u2013 RF ist ein wichtiger St\u00f6rfaktor in vielen Sandwich-ELISAs<\/td>\n<\/tr>\n<tr>\n<td>ANA-positiv (verschiedene Muster)<\/td>\n<td>Entwicklung von ANA-Assays, Validierung von Autoimmunpanels<\/td>\n<\/tr>\n<tr>\n<td>Anti-dsDNA-positiv<\/td>\n<td>Entwicklung von SLE-Biomarkerassays<\/td>\n<\/tr>\n<tr>\n<td>Anti-CCP-positiv<\/td>\n<td>Entwicklung von Assays f\u00fcr rheumatoide Arthritis<\/td>\n<\/tr>\n<tr>\n<td>Hochsensitives CRP erh\u00f6ht<\/td>\n<td>Kalibrierung von hsCRP-Assays und Linearit\u00e4tspr\u00fcfung<\/td>\n<\/tr>\n<\/table>\n<h3>Stoffwechsel- und Hormonerkrankungen<\/h3>\n<table>\n<tr>\n<th>Erkrankung \/ Marker<\/th>\n<th>Anwendung<\/th>\n<\/tr>\n<tr>\n<td>25-OH-Vitamin-D-Mangel (&lt;10 ng\/ml)<\/td>\n<td>Kalibrierung von Vitamin-D-Immunoassays \u2013 Linearit\u00e4t im unteren Bereich<\/td>\n<\/tr>\n<tr>\n<td>25-OH-Vitamin D ausreichend (&gt;30 ng\/ml)<\/td>\n<td>Basismatrix f\u00fcr Kalibratoren im Normalbereich<\/td>\n<\/tr>\n<tr>\n<td>Hyperlipid\u00e4misch (erh\u00f6hte Triglyceride)<\/td>\n<td>Pr\u00fcfung der Lip\u00e4mie-Interferenz (CLSI EP7)<\/td>\n<\/tr>\n<tr>\n<td>Ikterisch (erh\u00f6htes Bilirubin)<\/td>\n<td>Pr\u00fcfung der Ikterus-Interferenz<\/td>\n<\/tr>\n<tr>\n<td>H\u00e4molytisch (erh\u00f6htes freies H\u00e4moglobin)<\/td>\n<td>Pr\u00fcfung der H\u00e4molyse-Interferenz<\/td>\n<\/tr>\n<tr>\n<td>Schilddr\u00fcsenerkrankungen (Hypo-\/Hyperthyreose)<\/td>\n<td>Entwicklung von TSH-, T3-, T4-Assays<\/td>\n<\/tr>\n<\/table>\n<h2>Wie Disease-State-Serum in der IVD-Entwicklung eingesetzt wird<\/h2>\n<h3>1. Kreuzreaktivit\u00e4tspr\u00fcfung<\/h3>\n<p>Regulatorische Einreichungen f\u00fcr IVD (EU-IVDR 2017\/746, FDA 510(k)) verlangen den Nachweis, dass der Assay nicht mit potenziell st\u00f6renden Erkrankungen kreuzreagiert. Bei einem HIV-Antik\u00f6rpertest m\u00fcssen Sie zeigen, dass in Serum von Spendern mit Rheumafaktor, ANA, HBV, HCV, Malaria und anderen in der getesteten Population wahrscheinlichen Erkrankungen keine falsch-positiven Ergebnisse auftreten. Disease-State-Serumpanels liefern die Pr\u00fcfproben f\u00fcr diese Validierung.<\/p>\n<h3>2. Assaysensitivit\u00e4t am klinischen Entscheidungswert<\/h3>\n<p>Die klinische Sensitivit\u00e4t eines diagnostischen Assays bemisst sich an seiner F\u00e4higkeit, den Analyten am oder nahe am klinischen Entscheidungsgrenzwert zu erkennen \u2013 der Konzentration, ab der ein Patient als positiv gilt. Disease-State-Serum mit best\u00e4tigt niedrig-positiven Analytkonzentrationen (nahe am Cut-off) pr\u00fcft die untere Nachweisgrenze des Assays unter realen Matrixbedingungen.<\/p>\n<h3>3. Interferenzpr\u00fcfung (CLSI EP7)<\/h3>\n<p>Lip\u00e4mische, ikterische und h\u00e4molytische Serumproben sind Standard-Pr\u00fcfmaterialien f\u00fcr das Interferenzprotokoll CLSI EP7 \u2013 erforderlich f\u00fcr die meisten IVD-Einreichungen. SeamlessBio liefert daf\u00fcr gepooltes lip\u00e4misches (Triglyceride &gt;1.000 mg\/dl), ikterisches (Bilirubin &gt;20 mg\/dl) und h\u00e4molytisches (H\u00e4moglobin &gt;500 mg\/dl) Humanserum.<\/p>\n<h3>4. Serokonversionspanels zur Charakterisierung des diagnostischen Fensters<\/h3>\n<p>HIV- und HCV-Serokonversionspanels \u2013 Folgeproben von Spendern vor, w\u00e4hrend und nach der Serokonversion \u2013 zeigen, wie fr\u00fch ein Assay eine Infektion erkennen kann. Sie geh\u00f6ren zu den wertvollsten und am schwersten zu beschaffenden Materialien der IVD-Entwicklung.<\/p>\n<h2>Regulatorische und ethische Aspekte<\/h2>\n<p>Disease-State-Serum wird nach informierter Einwilligung von Spendern gewonnen, die ihre Diagnose kennen und der Verwendung ihrer Proben f\u00fcr Forschung und Diagnostikentwicklung zustimmen.
