False Measurement of Blood Amino Acids by LC-MS/MS in a Patient Dependent on Matrix Effect after Total Parenteral Nutrition Infusion.

CONCLUSION: This case demonstrates that TPN solutions affect the reference method of mass spectrometry measurement method due to the concentration of ingredients. We suggest that inaccurate results can be avoided by carrying out the sampling prior to TPN infusion in patients whose plasma amino acid levels will be measured.
