Sampling

• Blood sample (plasma/serum) taken with a syringe or capillary:
  - Serum in dry tubes
  - Plasma with anticoagulant.

• Compatible anticoagulant: see cartridge datasheet: Lithium heparin often recommended.

• Urine samples should be clear.

• It is recommended to centrifuge urine at 4000 rpm for 1 minute and to aliquot it in 1.5mL tubes.

• Minimal volumes (cf. Analyses Table).
  

Be careful:

• Use samples freshly collected and stored appropriately.
• For plasma: use compatible anticoagulants (see cartridge datasheet).
• If analysis > 8 hours: keep the sample at 4°C.
• If analysis > 48 hours: keep the sample frozen at -20°C or -80°C.
• Clear and simple identification of samples: provide a list matching the identifications (e.g.: excel table).
• Define the protocol : sample origin (species: mouse, rat, ...) and nature (serum/plasma/urine...)
