Acknowledgements
The work has been done in co-operation for and within
the community of clinical chemistry in the Nordic
countries. The staffs at the participating laboratori-
es made it possible.
Special thanks to other persons and institutions
(in alphabetical order) outside the NORIP project
group for invaluable contributions to the final
result:
Ole Blaabjerg, Odense University Hospital, Odense for
supervision of production of HIGH and LOW control
materials.
Ivan Brandslund, Vejle Hospital and Vejle Amt for
providing the project with the data registration pro-
gram.
Christian Enggaard, Nalge Nunc International for
providing sample tubes for free.
Nils Jørgensen, Sønderborg Hospital, Sønderborg for
data handling advise.
Ari Lahti, Rikshospitalet University Hospital, Oslo has
developed improved partitioning theory for reference
interval calculation and have been a general partici-
pant in the data handling part of the project.
Minna Loikkanen, Labquality, Helsinki for providing
the project with the method data base, providing us
with a part of CAL control material and for the pra-
ctical aspects concerning the project in Finland.
Arne Mårtensson and Gunnar Nordin, EQUALIS,
Uppsala for handling the practical aspects of the pro-
ject in Sweden, also as key persons in the heamatolo-
gical part of the project.
Elin Olavsdottir, Landspitallin, Reykjavik for transla-
ting the project description to English.
Inger Nørgaard, Hjørring Hospital, Hjørring for pro-
duction of control materials P and HIGH/LOW.
Heidi Steensland, Ullevål University Hospital, Oslo
started it all and have taken the responsibility for se-
lecting IFCC compatible enzyme method data for the
project.
Kjell Torgeir Stokke, my chief at Fürst Medical
Laboratory, Oslo, for letting me have a free hand with
this project.
Adam Uldall, DEKS, Herlev University Hospital,
Herlev, a key person in most aspects of the project:
Labels and sample tubes, supervision of production
and testing of CAL and X for NORIP purpose, target
value assignment and delivery to laboratories, bio
bank etc.
Petter Urdal, Ullevål University Hospital, Oslo, one of
the persons to take the initiative in the project, also
the organiser of the seven Norwegian groups who
evaluated the NORIP results.
Special thanks to Peter Felding, Per Hyltoft Petersen
and Per Simonsson for constructive comments to this
