Calcium oxalates are organic substances, present in many plants and other commonly eaten products. They are present in dock, asparagus, rhubarb, beets, dark beer, cocoa, coffee, tea, and others. The third of calcium oxalates found in urine comes from the digestive system, and the remaining two thirds from metabolic processes in the liver. This makes the presence of oxalates in a morning urine sample all but useless for diagnostic purposes. In order to estimate if the oxalate content in urine calls for treatment, the test must be conducted on an all-day urine sample, because only it can be compared to laboratory norms.
At the IIM Arcana, such a test can be performed. It is useful only if, in a few general urine tests, calcium oxalate crystals have been observed. The crystals are visible under a microscope in urinary sediment analysis.
Calcium oxalate crystals, similarly to other crystalline complements in urine, often show up in people with the “leaky gut syndrome.” Therefore, in case of this syndrome, the diagnostic value of calcium oxalate presence is questionable. Also, consuming vitamin C has an effect on the test—vitamin C is converted into oxalates by the body, therefore it should be avoided for 24 hours before the test. As I mentioned above, in case of intestine inflammation, the test is useless for diagnosis.
If there is a suspicion of a genetic disease called hyperoxaluria, a genetic screening test should be performed. Low-oxalate diet makes sens only for people suffering from this disorder, or for ones with a family history of kidney stones.
