Blood and Urine Analysis before and after Initiation of NO Supplementation

	Before NO Supplementation	After NO Supplementation
Plasma renin	normal	normal
Plasma aldosterone	normal	normal
Plasma brain natriuretic peptide (BNP)	not tested	normal
Urinary protein (mg/24 h, normal 28–141)	257 (elevated)	51 (normal)
Urinary nitrite (μg/ml, normal is not detectable)	not detectable	17 (elevated)
Urinary nitrate (μg/ml, normal is 0–124 μg/ml)	140 (elevated)	480 (elevated)

Urinanalysis showed a decrease in protein excretion together with increased urinary nitrate, as would be expected from therapy.
