Post Sarcoisosis:Protein/Trace Blood in Urine



I am an african american male. Age 35. Diagnosed w/sarcoidosis approximately 1 year, 3 months ago. Underwent prednisone therapy for 6-7 months. Doing fine, but had a physical done yesterday and trace amounts of blood, along with a protein level of 300 was discovered in my urinalysis. Not experiencing any UTI symptoms. Could this be from the sarcoidosis?


Dear Sir,

Sarcoidosis can affect any organ, including the kidneys. This could cause some proteins to be detected in the urine; however, it is unlikely to cause blood in the urine (referred to as hematuria). In some cases of sarcoidosis the vitamin D levels are high, causing high levels of calcium in the blood and/or urine. This can lead to the development of kidney stones, which can cause hematuria.

There are other causes of hematuria that should also be considered.

You are advised to consult your doctor to help determine the cause.
