3. Tailored Preparation

a) Biotest storage and use The Biotests are dispatched at room temperature, vacuum packed and with silica gel crystals to protect them from atmospheric humidity. Once delivered, they must be kept in the same way, between 3-8ºC, before expiration date. To hydrate the Biotest prior to use (this process should be carried out at least 24 hours prior to use), remove the silica gel crystals from inside the tube and fill it with Measurement Solution until the base of the Biotest is submerged. Once hydrated, the Biotest can be stored vertically at a temperature between 3-8ºC for a maximum of 15 days.

b) Reagent preparation

• LAC Measurement Solution (MS):

Both LAC1 Measurement Kit and LAC2 Measurement Kit contain 8 tubes (MLAC1 or MLAC2) to prepare the Measurement Solution, which is needed to prepare Reagents and Calibration Standards and to carry out the measurements. See Table 2 for the Measurement Solution preparation.
