  • complete solutions for screening newbornsanalytes, instrumentation andsoftware for neonatal screening
  • AnAlytes, instrumentAtion And softwAre for neonAtAl screening Everything you need for efficient neonatal screening Prediction before symptoms appear PerkinElmer provides you with the tools you need to For hemoglobinopathy testing PerkinElmer offers an run a successful and cost-effective neonatal screening additional range of products based on the RESOLVE® program. The test kit range covers most of the system and isoelectric focusing. congenital disorders for which neonates are currently screened. PerkinElmer is a pioneer in the application of tandem mass spectrometry (MSMS) to newborn screening, Our three conventional assay platforms are GSP ®, supplying instrumentation, informatics and reagents. AutoDELFIA® and VICTOR™. For these platforms, These products include the NeoBase™ MSMS reagent and subject to local registration requirements, we kit, which has 25 internal standards and supports supply automatic or manual assays for T4, TSH, detection of more than 30 disorders. 17a-hydroxyprogesterone, IRT, Hb and Toxoplasma, as well as for Phenylalanine, GALT, TGAL, Biotinidase Assays for phenylalanine, g6pd and toxoplasma and and G6PD. Kits have been developed specifically for immunoassays for Hb are not available in the usA or neonatal screening, and employ proven fluorescence canada. Additionally, assays for tgAl and biotinidase chemistries to assure excellent performance. are not available in canada. All tests are based on dry blood spot samples measured in 96-well microtitration plates. To prepare the plates a variety of punching devices are available, providing the level of automation desired by the laboratory.2
  • AssAy processingConventional assay platforms GSP® ** is a multitechnology instrument for neonatal dried blood spot assays employing DELFIA chemistry as well as prompt fluorescence or absorbance-based measurement technologies. From plate loading to results output, GSP performs all assay stages automatically. For The AutoDELFIA® laboratories wishing to implement full automation immunoassay system allows from specimen reception to results delivery, the automatic processing of GSP instrument is compatible with punchers such neonatal assays employing as PerkinElmer’s AutoPuncher™ device and with DELFIA chemistry.

It is supportedwith a range of devices for samplepreparation including the DBS Puncher,DELFIA Washer-Diskremove, DELFIAPlateshake and/or TriNest™ Incubator Shaker.Sample preparation devices AutoPuncher™ provides full automation in the punching of 3.2 mm and 6 mm dried blood spot disks from specimen cassettes, and placement of the disks in the wells of microtitration plates. MultiPuncher™ can prepare up to six microtitration plates The DBS Puncher has simultaneously. Two a changeable head to different disk sizes, 3.2 mm allow the use of disks and 6 mm, can be punched with diameters of 3.2, from the same spot. 4.7 or 6 mm. Two plates may be loaded to allow simultaneous preparation of different assays. 3
  • A full rAnge of screening AssAys The diseases screened today are varied. What they to meet todAy’s needs have in common is that without timely treatment they will cause severe retardation of a child’s development. This represents a high cost to the child and their family, to the health care provider and to society in general. PerkinElmer’s assays help secure the first stage of the process to find affected individuals in time. Congenital hypothyroidism (CH) Galactosemia The incidence of CH is 1:3000 to 1:4000 in the USA. If The incidence of galactosemia is 1:30000 to 1:60000 in the untreated CH can lead to severe developmental or intellectual USA. The untreated disorder will cause poor development, delay. Treatment in time allows affected children to develop and in the worst case may be fatal. Treatment consists of a normally. galactose-free diet and allows remission of symptoms. PerkinElmer Neonatal hTSH and Neonatal T4 assays offer PerkinElmer’s Neonatal GALT assay is intended for the two alternative screening strategies for CH. The assays are determination of GALT (galactose-1-phosphate uridyl time-resolved fluorometry-based assays using dried blood spot transferase) concentrations as an aid in screening for classic samples. galactosemia. PerkinElmer’s Neonatal TGAL assay is intended for the determination of total galactose (galactose and galactose-1-phosphate). This measurement provides an Neonatal hTSH GSP** AutoDELFIA VICTOR2D aid in screening for deficiency of any of the three enzymes Neonatal T4 GSP* AutoDELFIA VICTOR2D contributing to a-D-galactose metabolism. Neonatal GALT GSP** VICTOR2D Phenylketonuria (PKU) Neonatal TGAL GSP* VICTOR2D** The incidence of PKU is 1:10000-1:20000 in the USA. If assay in development untreated it can lead to developmental or intellectual delay. Prompt treatment with a phenylalanine restricted diet allows normal development. Congenital adrenal hyperplasia (CAH) The incidence of CAH is 1:15000 in the USA. CAH is a group The PerkinElmer Neonatal Phenylalanine assay is based on the of disorders, the most serious one being potentially fatal. For fluorescence of a phenylalanine-ninhydrin reaction product, all classes of CAH, early treatment can greatly benefit the which is enhanced by the dipeptide L-leucyl-L-alanine. The patient. use of a succinate buffer and the addition of copper further improve the analytical specificity and sensitivity.

  • Products for expanded screening Amino acids and acylcarnitine assays using tandem mass spectrometry PerkinElmer has worked with numerous screening programs seeking to implement expanded newborn screening employing tandem mass spectrometry. Using this technology laboratories can measure more than 30 amino acid and acylcarnitine analytes in less than two minutes from a single dried blood spot specimen. For sensitive, reliable amino acid and acylcarnitine assay For AA/AC detection or other newborn without a derivazation stage, our NeoBase™ MSMS reagent tests, PerkinElmer supplies the TQD MSMS kit, has 25 internal standards and 23 high and low controls. Instrument, which is used with the 2777C The kit components have been carefully validated to work Sample Manager and 1525 μ Binary Pump. together to produce results to assure the laboratory 100 % Employing well-tested and highly reliable Waters confidence. triple quadrupole mass spectrometer technology, TQD offers the proven stability of the Waters Neonatal AA/AC TQD MSMS Instrument Quattro™ micro, but superior transition times due to T-Wave™ collision cell technology. The TQD instrument has a very small footprint (35.5 cm x 84.8 cm, or 14”x 33.5”). For Tyrosine type 1 – now it’s easy to detect succinylacetone By ordering PerkinElmer’s Succinylacetone Assay Solution and adding this to samples at the same time as you add internal standard, you can extract succinylacetone along with amino acids and acylcarnitines. This allows simultaneous detection of succinylacetone alongside the other key metabolic disease markers with the NeoBase kit.6
