IMMULITE ® 2000 Homocysteine 2 IMMULITE 2000 Ho mocysteine (PIL2 KHO-14, 2007-11- 20) English Inte nded Use: For in vitro diagnostic use with the IMMULITE 2000 Analyzer — for the quantitative determination of L-homocysteine in human plasma or serum.
IMMULITE 2000 Ho mocysteine (PIL2 KHO-14, 2007-11- 20) 3 synthesis of HCY will take place in red blood cells after sampling. Samples should be stored on i ce between the time of sampling an d centrifugation. Note that storage on ice makes the use of serum samples particularly difficult.
4 IMMULITE 2000 Ho mocysteine (PIL2 KHO-14, 2007-11- 20) Storage: 30 days (after opening) at 2–8°C or 6 months (aliquotted) at –20°C. Barcode labels are provided for use with the diluent. Before use, place an appropriate label on a 16 × 100 mm test tube, so that the barcodes can be read by the on-board reader.
