The Vitamin C Test Strips, sold by Riordan Clinic, come in a pack of 50. These are testing strips designed to measure and monitor Vitamin C levels in urine to ascertain your metabolic requirement, helping manage a user's daily vitamin consumption.

Utilization of these strips simply involves dipping a strip into a urine sample, waiting for a color change, and then comparing this color to the provided color chart to determine the concentration of Vitamin C. The resultant reading is qualitative rather than quantitative, to monitor the sufficiency or deficiency of Vitamin C in the body, rather than providing exact measurements.

The compact and easy-to-carry packaging of these strips make them convenient for use anywhere. The formula of the reagents on the test strip is exclusive to Riordan Clinic and contributes to the accurate assessment of vitamin C levels.

It should be noted that certain substances or conditions, including Vitamin C supplements, can impact the accuracy of the test results. These strips are meant for personal use only and not intended as a professional diagnostic tool. It is advised to consult a healthcare professional for accurate and professional health assessment. The product does not come with any personal medical advice or instructions for adjusting vitamin intake.
