It involves the quantitative determination of phenvlalanine, tyrosine and the phenylalanine to tyrosine ratio (Phe/Tyr) in blood specimens dried on filter paper. This will aid in identifying newborns with PKU. It is intended for use by trained, qualified laboratory personnel. ## Device Story Kit extracts amino acids from dried blood spots on filter paper using isotopically labeled internal standards; methanol/water extraction solution. Analysis performed on tandem mass spectrometer. Device quantifies phenylalanine, tyrosine, and Phe/Tyr ratio. Used in clinical laboratory settings by trained personnel. Output provides quantitative concentration data to aid clinicians in identifying newborns with PKU. ## Clinical Evidence Bench testing only. Comparative study of 3,679 samples analyzed by both fluorometric method and NeoGram TMS method. Results: Fluorometric mean 1.1 mg/dl (S.D. 0.3); TMS mean 1.1 mg/dl (S.D. 0.2). ## Technological Characteristics In vitro diagnostic kit; utilizes tandem mass spectrometry (TMS) for analyte quantification. Employs 96-well microtiter plates. Sample input: 3mm punched dried blood spot. Extraction: methanol/water solution. Detection: mass spectrometric assay using isotopically labeled internal standards. ## Regulatory Identification A phenylalanine test system is a device intended to measure free phenylalanine (an amino acid) in serum, plasma, and urine. Measurements of phenylalanine are used in the diagnosis and treatment of congenital phenylketonuria which, if untreated, may cause mental retardation. ## Predicate Devices - Isolab Phenylalanine Test Kit ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Norton, OH 44203 Telephone: 330-825-4525 Fax: 330-825-8520 Contact person: Hank Juske, Director, Regulatory Affairs Trade name: NeoGram PKU Tandem Mass Spectrometry Kit (MS-7960) Common name: Phenylalanine screening test kit Classification name: Phenylalanine test system Legally marketed predicate device: Isolab Phenylalanine Test Kit Device description: The assay involves the extraction of dried blood spots with a solution containing stable, isotopically labeled internal standards. The response of each amino acid relative to the isotopically labeled standards in the kit is proportional to their actual concentration. The analysis of the material is performed on a tandem mass spectrometer. Control material contained in the kit allows for verification of performance for the test run. Intended use: The NeoGram PKU Tandem Mass Spectrometry Kit is intended for screening for Phenvlketonuria (PKU). It involves the quantitative determination of phenvlalanine, tyrosine and the phenylalanine to tyrosine ratio (Phe/Tyr) in blood specimens dried on filter paper. This will aid in identifying newborns with PKU. It is intended for use by trained, qualified laboratory personnel. Similarities/ Differences with the predicate device: | Similarities: | |---------------------------------------------------------------------| | -Intended use is the same. Both kits are for screening of newborns. | | -Both kits are intended to screen for the defect PKU. | | -Both measure the analyte Phenylalanine | | -Both use dried blood spots on filter paper for sample collection | | -Both use standards and controls dried onto filter paper | | -Both assays are quantitative | | -Sample size (3mm punched spot) is the same | | -Both employ a 96 well microtiter plate | {1}------------------------------------------------ -Fluorometric based chemistry vs. spectrometric assay Differences: -Linearity of approximately 21mg/dl fluorometric vs. 35 mg/dl TMS -Measurement by calibration curve versus internal standard comparison -Zinc sulfate/ethanol extraction solution vs. methanol / water solution Mean value/ standard deviation of 3679 samples run by: Fluorometric method: X= 1.1 mg/dl S.D.= 0.3 Tandem Mass Method: X= 1.1 mg/dl S.D = 0.2 {2}------------------------------------------------ DEPARTMENT OF HEALTH & HUMAN SERVICES Image /page/2/Picture/1 description: The image shows the seal for the Department of Health & Human Services USA.
