The Sulkowitch Urine Calcium Test is designed for the home user to self-test first morning urine to check for calcium in urine which in turn can help the user to assess calcium retention. Calcium is the most common mineral in the body and one of the most important.

Almost all of the calcium in the body is stored in the bone, the rest is found in the blood. The test uses reagents in drops to measure the presence of calcium in urine. Determination of the calcium content in urine is based on the reaction of calcium ions with the reagent provided to form a precipitate.

The reagents were designed in conjunction with a naturopathic health care provider and an independent laboratory in Canada who also provided measurement of the results.

Note: This test may not be available in Canada and some countries due to health regulations.
