Intended Use

ALFIS Vitamin D in conjunction with ALFIS-3 Analyzer is an enzyme-linked fluorescence immunoassay intended for in vitro diagnostic use at clinical laboratories for the quantitative measurement of Total 25-hydroxy Vitamin D (25-OH Vitamin D) in human serum, lithium heparin plasma and sodium heparin plasma.

ALFIS Vitamin D is indicated to be used as an aid in the determination of Vitamin D sufficiency in adults.

ALFIS-3 Analyzer is a fluorescence-scanning instrument using magnetic beads and alkaline phosphatase enzyme system for in vitro diagnostic use in conjunction with various ALFIS immunoassays intended for measuring the concentration of designated analytes in human blood and other specimens.

Device Description

ALFIS Vitamin D Test Cartridge is a plastic structure molded in the form of a disposable, self-contained, unitized device which houses the 'magnetic bead', 'antibody-alkaline phosphatase-conjugator (Ab-ALP)', 'sample diluent', 'diethanolamine (DEA)', '4-Methylumbelliferyl phosphate (MUP)', 'washing buffer'; all of which are integral components of ALFIS Vitamin D test.

ALFIS Vitamin D test cartridge is an elongated structure having 150.8 mm length, 17 mm width and 16 mm height.

'ALFIS Vitamin D Test ID Chip' is a flat, rectangular device with its main body measuring 23 mm × 27 mm. Half of the portion along the breadth of the main body is 5 mm thick while remaining half is 3 mm in thickness. Another rectangular portion measuring 12 mm × 10 mm × 2 mm protrudes out from the breadth of apical side of the 3 mm-thick portion of the main body.

ALFIS Vitamin D Test ID Chip is an electronic memory device fitted into a plastic matrix. Lot-specific 'ALFIS Vitamin D Test ID Chip' is an integral component of ALFIS Vitamin D test system.

ALFIS-3 analyzer is a compact, bench-top, automated, fluorometric analyzer measuring 422 mm (L) x 270 mm (W) x 292 mm (H). ALFIS-3 weighs 13.0 kg.

ALFIS-3 analyzer is a fluorometer instrument of closed-system analyzer type.

'ALFIS Vitamin D Calibrators' needs to be tested by user laboratories for periodic calibration of ALFIS Vitamin D test system.

'ALFIS Vitamin D Controls' needs to be tested by user laboratories periodically for monitoring the performance of ALFIS Vitamin D test system.
