低血钾时，正常肾脏有保钾功能。
血钾水平降低的同时尿钾水平升高提示肾脏保钾异常。
Elevated urinary potassium levels with low blood potassium levels suggest the kidneys are having problems retaining potassium.
还可能与其他药物相互作用，尤其是心血管药物，例如ace抑制剂，受体阻断剂和保钾利尿药。
It can also interact with other medications, especially certain types of cardiovascular medications such as ACE inhibitors, receptor blockers and potassium-sparing diuretics.
它还可能与其它药物相互作用，特别是心血管一类药物，例如ace抑制剂、受体阻滞剂和保钾利尿剂。
It can also interact with other medications, especially certain types of cardiovascular medications such as ACE inhibitors, receptor blockers and potassium-sparing diuretics.
醛固酮抑制剂和血管紧张素转换酶抑制剂可辅助阻断RAAS，并有助于防止远端肾小管钾的损失。身体保钾，这样可减少口服补钾量。
Aldosterone inhibitors and ACE inhibitors help block the RAAS and help prevent potassium loss in the distal tubules. The body conserves potassium, and less oral potassium supplementation is needed.
这有助于肾脏突变的远端保钠，但会以失钾为代价。
This helps the kidneys retain sodium distal to the site of the mutation but at the expense of losing potassium.
这有助于肾脏突变的远端保钠，但会以失钾为代价。
This helps the kidneys retain sodium distal to the site of the mutation but at the expense of losing potassium.
