Publication number: 20170131209Abstract: The invention relates to a method and apparatus for detecting undesired measurement conditions in a sample container. The method comprises measuring a fluorescent property of the sample container comprising a sample substrate with impregnated blood sample and incubation buffer to which the blood sample is to be eluted, and determining, based on temporal and/or spectral characteristics of the fluorescent property, whether the fluorescent property is characteristic to a sample container comprising a sample substrate and incubation buffer under said undesired measurement conditions or to a sample container suitable for optical measurement of analyte contained in the sample. Thus undesired measurement condition can be a floating sample substrate or a foreign body in the sample container. By means of the invention, reliability of neonatal screening, for example, can be increased.Type: ApplicationFiled: January 19, 2017Publication date: May 11, 2017Inventors: Ville Väisänen, Jarkko Karvinen, Pertti Hurskainen, Elina Tuomola

Publication number: 20110294227Abstract: The present invention relates to a method for determining the risk of a pregnant woman developing pre-eclampsia. The method comprises i) determining the level of one or more biochemical markers in a sample obtained from a pregnant woman, and ii) comparing the level of the at least one biochemical marker in the sample with the level of the same biochemical marker in a control sample. A difference in the level of the biochemical marker in the sample relative to the control sample is indicative of an increased risk of developing pre-eclampsia. The isoform biochemical markers are preferably P1GF-2 and P1GF-3. The present invention relates also to a method for determining whether a pregnant woman has pre-eclampsia and as well as a kit for assessing the risk or presence of pre-eclampsia. In addition, the invention relates also to a computer program used in these determinations.Type: ApplicationFiled: November 20, 2009Publication date: December 1, 2011Applicants: PERKINELMER HEALTH SCIENCES, INC., WALLAC OY, NTD LABORATORIES, INC.Inventors: Tarja Ahola, Heini Frang, Teemu Korpimäki, Pertti Hurskainen, Mark N.

Patent number: 5998146Abstract: The invention is a luminescence energy transfer based bioaffinity assay comprising a first group labeled with an energy donating compound (donor) and a second group labeled with an energy accepting compound (acceptor), wherein the donor is a luminescent lanthanide chelate having a long excited state lifetime and the acceptor is either a luminescent compound having a short excited state lifetime or a nonluminescent compound. The increase or decrease, respectively, in the energy transfer from the donor to the acceptor resulting from shortening or lengthening, respectively, of the distance between the said groups, is measured. Characteristic for the invention is that the lanthanide energy emission and the acceptor energy absorption do not essentially or not at all overlap each other.Type: GrantFiled: July 17, 1998Date of Patent: December 7, 1999Assignee: Wallac OyInventors: Martti Latva, Ilkka Hemmila, Kaj Blomberg, Pertti Hurskainen

Patent number: 5256535Abstract: A method for the detection of a nucleotide sequence of a nucleic acid in a sample. The method comprises the steps: (i) contacting under hybridization condition the single stranded form of the nucleotide sequence with a single stranded nucleic acid probe, in which plurality of rare earth metal chelate groups is covalently linked via a water-soluble polymer of non-nucleic acid structure to a nucleotide acid that as one of its strand has the nucleotide sequence to be detected and as the other strand the nucleotide sequence of the probe, and (ii) detecting the formation of double stranded nucleic acid. The plurality of rare earth metal chelate groups have at least one metal ion selected from the group consisting of Eu.sup.3+, Sm.sup.3+, Tb.sup.3+ and Dy.sup.3+ as the chelated rare earth metal. The probes as given above are also claimed.Type: GrantFiled: June 16, 1988Date of Patent: October 26, 1993Inventors: Jyrki Ylikoski, Pertti Hurskainen, Patrik Dahlen, Christian Sund, Timo Lovgren, Marek Kwjatkowski
