    Is There Any Tests to Know If I Have Renal Tubular Acidosis

    Is There Any Tests to Know If I Have Renal Tubular AcidosisRenal Tubular Acidosis, short for RTA, is a disease that occurs when the kidneys fail to filter acids into the urine, which causes a person’s blood to remain too acidic. Without proper treatment, chronic acidity of the blood leads to growth retardation, kidney stones, bone disease, chronic kidney disease or even kidney failure. Well then, is there any tests to know if I have renal tubular acidosis?

    The list of diagnostic tests mentioned in various sources as used in the diagnosis of Renal Tubular Acidosis includes:

    1. Serum bicarbonate

    It is the most senstive and specific test for most forms of RTA. The finding of low serum bicarbonate concentration is the usual starting point for investigating metabolic acidosis. Typically, between 15 to 19 mmol/L in proximal RTA; classic distal RTA may present with a lower serum bicarbonate; hypobicarbonataemia is not as severe in hyperkalaemic (type IV) RTA.

    2. Serum chloride

    In the absence of confounding conditions, patients with complete forms of RTA are hyperchloraemic, but chloride may be normal in incomplete distal RTA.

    3. Urine pH

    Most sensitive and specific test for diagnosis of classic distal RTA. The diagnosis of classic distal RTA is made when urine pH cannot be lowered below 5.5 in the face of hyperchloraemic metabolic acidosis with abnormally low arterial p

    4. CT/spiral CT

    CT can be used to assess the urinary tract for obstruction when ultrasound is unavailable or ultrasound examination is limited by patient size. CT can also be used to assess for stones and ureteral obstruction.

    In addition the mentioned above, if you have the symptoms like bone pain, mild dehydration, urinary stone and so on, you should also do tests to make a diagnosis. Any questions, please be free to contact our Online Doctor or leave a message below directly.
