Sodium and potassium cations in serum

The balance of electrolytes in the body is maintained by a function called homeostasis. Diagnosis of sodium and potassium levels are determined with a blood test. This Application Note describes K+ and Na+ cations analysis in serum with the Wyn-CE system and a contactless conductimetry detection.

L'avis de l'expert : Rapid and sensitive method for diagnosics using a low number of samples (1 µL).
