Measurement of NO production in vivo is difficult because of its short half-life and the need for specialised equipment. Citrulline level can be used as surrogate marker for estimating NO production.

Indication for the detection of urinary L-citrulline

  • Estimating the NOS activity (NO production)
  • Detection of nitrosative stress due to an enhanced synthesis of inducible nitric oxide (iNO)
