Thanks for the query.
You have not mentioned your son's age.Nephrotic syndrome
in childhood often relapses. A relapse is characterized by increase in urine albumin
to 3+ or more and requires increase in the dose of medications.
Urine albumin of 1+ usually does not indicate a relapse and the pt. can be kept on the same dose of medications. However the urine test has to be repeated frequently to monitor if albumin is increasing.
Hope this answers your query.
