|| LDL standard is a standardized preparation of human plasma in LDL Diluent. After proper reconstitution with water, the preparation shows a dose-response that is identical to that of fresh human plasma in Glycacor. The reconstituted material is standardized against a purified sample of glycated LDL, and the actual value is dependent upon manufacturing lot. The reconstituted LDL Standard shows some turbidity. It is unstable to storage after reconstitution, and must be used immediately.
