No blood test: There is no blood test to detect amyloidosis. Sophisticated laboratory techniques called electrophoresis or free light chain assays may reveal early evidence of some amyloid proteins. A biopsy is needed to confirm a diagnosis of amyloidosis and determine the specific type of protein involved in the disease. ...Read moreSee 1 more doctor answer

No: Amyloidosis is diagnosed by tissue biopsy such as a rectal biopsy wherein the amyloid in the tissue is detected by the congo red stain. It is the accumulation of particular misfolded proteins in the space between cells (extracellular matrix) that distinguishes amyloidosis. There are many types of amyloid proteins than can cause amyloidosis. ...Read moreSee 1 more doctor answer
I have been diagnosed with lichen amyloidosis without proper test conducted by a dermatologist at malaysia. Should i get 2nd opinion?
What is the best test to point toward (or rule out) possible al amyloidosis? Serum free light chain assays or urine free light chain assays?
Does pathology routinely test for amyloid? Recently had thyroidectomy and have smoldering myeloma so would like amyloidosis to be ruled out.
Not routine: A special stain for amyloid is not routine for thyroid. However, amyloid can be seen on routine slides, so if there is a fair amount of it, pathologist can see something, but special stain is needed to confirm it is amyloid. important that the pathologist knows the medical history, so can be on the lookout for amyloid, which is not common and can be subtle. You can call MD and ask to make sure. ...Read moreSee 1 more doctor answer
Testing for amyloidosis. Two 24-hr urine protein labs both showed protein 6.3mg/dl. 1st test was 140mg/24hrs from volume of 2225ml of pee. 2nd test was 129.2mg/24hrs from 2050ml pee. Both in range, but if peed more would have been over limit. Worry?
No worries please.: The test results take into account the concentration of protein in the urine, not just the amount. If you had consumed more fluids and made more urine, the total amount of protein would be the same even tho there was more urine. Example: if you have a cup of salt water and add more water to it, the water will be less salty but the total amount of salt will stay the same. ...Read moreSee 1 more doctor answer
