Potassium sodium test?

[kisekis]

Hello. I have questions related to sodium and potassium. Hope there will be some answers.

So for urine 24 hours test wouldnt the result depend most on what we consume? How would it check how much we can ratain water. Also if theres no baseline on how much we should consume during the test?

Im also confused finding the right ratio for potassium sodium since the serum test isnt reliable. Since theres also research and discussion here saying salt load will decrease aldoesterone(bad) and decrease potassium, increase adrenaline cortisol. I get complicated result from salt load.

Also balancing mineral is complicated too such as magnesium calcium. Cause too much of 1 could cause problem. I also read there are a few people here who doesnt do good with salt load depends on their condition. 

Trying increase each one and feel the difference in our own also hard for me cause my body is just weird. Hard to identified.

Anybody has an idea/tips? I cant get the blood volume test and mineral in cell test.

Would the 24 hours urine and blood sodium potassium, plasma renin activity, aldoesterone blood test reliable to detect low blood volume, electrolyte issue?

Thank you for whoever reply

No, there is virtually no clinical value in measuring urinary sodium or potassium in dysautonomia. Any attempt to estimate blood volume from this is based on the presumption of normal fluid and sodium handling, which is often defective in us. 

There is value in collecting urine to measure the volume - large volumes may indicate diabetes insipidus (but is more often due simply to how much we drink), or to measure catecholamines, to help exclude a phaeochromocytoma.

Plasma renin & aldosterone are useful, for example I produce neither, hence the likely reason I am clinically volume deplete.

In theory, any urine testing is the excess your body is not using. So if your urine numbers are high that means your numbers in your body are too high. Obviously it doesn't always work this way, but that is the theory.

@StayAtHomeMom. I don't think that's the case even in theory. There are conditions in which you have high urine sodium or potassium or both due to your body's inability to moderate it ( and hence hold onto too little of it). That's why if you have POTS it's important to rule out such conditions as a cause.

Thanks everyone for the reply.

Im still confused.

@joiedevivrehow to rule out the condition?

I can only get standard test many advanced test arent available

@StayAtHomeMomi see but thats also depends on what we eat/consume right? so theres no baseline to see how much it affected the result? We just eat/consume our normal salt, potassium?

@bombsh3ll i see like you said its also depends on how much we drink. Shouldnt there be a baseline for that? Or we should write it down...?

Is it the standard aldoesterone blood test and plasma renin blood test? Or the more advanced ones? Cause people say test like ace angiotensin but i dont think its available.

I have low blood volume diagnosed through a hemodynamics test. I had this done at the Cleveland Clinic. My blood work often shows low potassium levels.  This was one of the only findings I had in the beginning.
