What about calculating TTKG to aid in the differential diagnosis? Cybergoth 12:18, 27 August 2005 (UTC)
- Put it in. alteripse 21:34, 27 August 2005 (UTC)
Yes, that would be useful. Here is an online calculator. JFW | T@lk 23:08, 27 August 2005 (UTC)
Deleted "Liddles Syndrome" & "Pseudohyperaldosteronism" from the Differential Diagnosis, since those are associated with HYPOkalemia. 129.22.127.147 02:51, 10 March 2006

[edit] hyperkalemia wrong information in article
Increased extracellular potassium will cause hyperpolarization and not depolarization of the cell membrane. dont you agree?
Disagree: Imagine a typical cell which has a membrane voltage determined predominately by conductance through potassium channels. The point of equilibrium (where the membrane potential will equilibrate) is the Nernst potential for K, which equals -60mV*Log([K]i/[K]o). As [K]o rises, the membrane will equilibrate at a less negative potential. Hence, the cell will be depolarized in the setting of hyperkalemia. DanLevy 04:53, 10 June 2006 (UTC)

Will delete comment by user 85.167.25.246 regarding Hyperkalemia causing acidosis. True that cardiac arrest, or weakness of diaphragmatic muscles could lead to hypoxia/ischemia that would cause acidosis, but I think that these would be extreme examples, and the statement is otherwise misleading.
