Microalbumin
Microalbumin is a small amount of albumin in the urine that can be an early sign of kidney damage, especially in people with diabetes or high blood pressure.
iollo markers that associate with Microalbumin
Alanine
Like glycine, alanine is an amino acid that can be reabsorbed in the renal tubules. Tubular dysfunction associated with early diabetic kidney disease may cause urinary wasting of alanine in addition to albumin.

Glycine
Glycine is an amino acid that can be reabsorbed in the proximal tubules of the kidneys. Impaired tubular reabsorption of glycine may lead to increased urinary glycine excretion along with microalbuminuria, an early marker of kidney damage.

Taurine
Taurine is an abundant amino acid in the body. Urinary taurine wasting can occur along with microalbuminuria in the setting of tubular dysfunction and early nephropathy.
