    Folkehelseinstituttet er et statlig forvaltingsorgan underlagt Helse og omsorgsdepartementet. Vårt samfunnsoppdrag er å produsere, oppsummere og kommunisere kunnskap for å bidra til godt folkehelsearbeid og gode helse- og omsorgstjenester. På denne måten bidrar vi til bedre helse i Norge og globalt. Folkehelseinstituttet har en sentral rolle i den nasjonale og globale helseberedskapen og som kunnskapsprodusent i helsesystemet. Beredskapsarbeidet skjer i tett samarbeid med nasjonale og internasjonale myndigheter og fagmiljø. Instituttet er statens smitteverninstitutt med tilhørende funksjoner og ansvar. Dette innebærer blant annet ansvar for innkjøp, lagring, distribusjon og oppfølging av vaksiner i vaksinasjonsprogrammene. I rollen som kunnskapsprodusent i helsesystemet skal instituttet understøtte Helse- og omsorgsdepartementet, Helsedirektoratet, Direktoratet for e-helse, Mattilsynet, Miljødirektoratet og andre nasjonale og lokale myndigheter og tjenester som er relevant kunnskap. Dette innebærer at instituttet skal sammenstille og kommunisere kunnskap om helserelaterte tema for å bidra til kunnskapsbasert praksis og offentlig debatt. Instituttets fagområder, drive omfattende kunnskapsformidling samt delta internasjonalt arbeid på instituttets fagområder mv. instituttet drifter og utvikler moderne infrastruktur for kunnskap, som omfatter helsedata og digitaliserin

    description:
    The Norwegian Institute of Public Health (NIPH) (hereinafter referred to as the “Customer”) intends to procure a multiplex protein detection system with dual-reporter fluorescence for immunological analyses, specifically for the simultaneous detection of multiple antibody isotypes and specificities within a single sample. This investment aims to strengthen laboratory capacity in the areas of surveillance, preparedness, research, and the national vaccination program. The procurement includes a multiplex detection instrument along with accompanying software, installation, training kits, warranty, and long-term service and maintenance. A framework agreement for the future purchase of system-specific consumables and post-warranty maintenance services is also required. See appendix 4 chapter 2 for further information. The instrument must support high-throughput immunological analyses with dual-reporter fluorescence. It should be compatible with existing Luminex/Bio-Rad-based workflows (e.g., Bio-Plex Manager 6.2) or similar solutions. This strategic investment is expected to improve operational efficiency, data integrity, and scientific output.

How an AI agent should use this page

Ground rule: Navigate with HTML GET links to keep explanations and relationships. Use the page's JSON alternative only when concrete values must be extracted, compared or computed.

How to use the search_doffin lookup

  1. Replace the placeholders in the HTML GET template; remove optional parameters you do not need.
  2. Check types, units, limits and ID formats in the parameter table.
  3. Follow linked results to canonical pages before combining sources.

Misreading to avoid: An empty list means "no results for this lookup". An error message or unavailable source does not mean the data does not exist.

Source-specific next step

Go to the source page for other operations. Use the JSON template only after the HTML result shows that the parameters and source are correct.
