Urine24 hour Urine
Sterile Jar24 hour urine - PLAIN bottle
24-hour urine - ACID bottle
although plain is preferred, can be analysed on Acid collection.
If an Oral Salt Loading Test is requested, collect the specimen in an acidified 24-hour urine bottle instead of a plain bottle. See instructions in Urine Aldosterone testing.
These tests are of value principally -
In differentiation of the cause of low plasma sodium
To differentiate btween pre-renal and renal failure in certain circumstances where oligouria is present (urine Na)
In acute disturbances of sodium and potassium homeostasis, as a guide to immediate therapy
To assess volume status
While a 24 hour urine collection is the gold standard, in some cases a spot urine may be an adequate alternative.
