• Why choose Kidney Damage Tests?

Tests for kidney damages focus on the content of urine, which totally include 12 indexes as follows.

- U-TP (Urinary Total Protein). A urine total protein test is conducted to detect excess protein in the urine. When U-TP>150mg/L, kidney problems may be expected.

- U-malb (Urinary Microalbumin). Microalbumin indicates the early damages to glomerular mechanical barrier. The normal reference is Umalb≦30mg/L.

- U-TRF (Urinary retinol binding protein). U-TRF indicates the early damages to glomerular charge barrier. The normal reference is Umalb≦1.9mg/L..

- U-IgG (Urinary Immunoglobulin G). Large amount of U-IgG tells that glomerular filtration membrane is damaged seriously. The normal reference is Umalb≦8.8mg/L.

- Uβ2-M (Urinary β2-Microalbumin). The characteristics of beta2 microglobulin (B2M) make it useful as a tumor marker for some blood cell cancers, for detecting kidney damage, and for distinguishing between glomerular and tubular disorders of the kidney.

- Uα1-M (Urinaryα1-Microalbumin). It indicates the reabsorption of renal tubules, which is a better reference than B2M in most conditions.

- α2-M (Urinaryα1-Macroalglobulin). Its appearance indicates postrenal proteinuria.

- light chainκis always the marker of prerenal proteinuria which is a common symptom of light chain disease, multiple myeloma, lymphoma etc.

- light chainγhas a similar function of light chain γ.

- U-NAG (Urinary N-acetyl-beta-D-glucosaminidase). Urinary concentration of NAG is a sensitive index of renal tubular function.

- U-GGT (Urinary Gamma-glutamyl transpeptidase). Urinary concentration of NAG is a sensitive index of renal tubular function.

- Urinary Osmotic Pressure. It is a smart index to reflect the concentration and dilution function of renal tubules.

Why choose Kidney Damage Tests?

It helps your doctor make an overview about your kidney medical condition, including:
● whether your kidney are injured or not
● Which part of your kidney are injured, glomeruli or renal tubules?
● How severity is your kidney damages? The tests offer directions for your doctor to choose drugs for you.
● The tests find your sensitivity to current drugs and are the basis for your doctor to consider drug changes for you.
