Where To Buy Vitamin C Test Strips


Background: Vitamin C is a strong reducing agent found at high levels in various foods, and it may influence the results of urine strip tests even at an ordinary consumption levels. After oral administration, we measured urine vitamin C levels using urine strips and evaluated whether vitamin C interfered with various test items. The utility of a urine strip with a vitamin C indicator was assessed.


Methods: Thirty-three healthy volunteers each ingested 1,000 mg of vitamin C. Their urine samples were tested for vitamin C using a URiSCAN 11 strip (YD Diagnostics, Korea) before and after administration of vitamin C. Standard materials were added to normal pooled urine to generate urine samples with various concentrations of the analytes tested (blood, bilirubin, nitrite, leukocytes, and glucose), and vitamin C was spiked to predetermined levels. These samples were then tested using two urine strips - URiSCAN and Chemstrip test strip (Roche Diagnostics, Germany) - to evaluate interference from vitamin C. In clinical samples with positive vitamin C results, microscopic and chemical analyses were also conducted to examine the differences.


Results: Thirteen urine samples from the 33 volunteers were positive for vitamin C before ingestion, and all subjects were positive after ingestion. Vitamin C spiking of urine demonstrated false-negative results at various concentrations. Of 159 specimens with positive results for vitamin C, 14 showed discrepant results after additional confirmatory tests.


Conclusions: Vitamin C in urine can cause significant interference with urine strip tests. A urine strip with a vitamin C indicator is useful to reduce the risk of incorrect results in regard to disease states.


Our dipstick results for glucose, leukocyte esterase, and hemoglobin for samples with added vitamin C changed compared with the results for the original samples without vitamin C. The degree of interference increased with the urinary vitamin C concentration, as reported previously.6 As is well known, vitamin C did not interfere with the protein test.1 However, we also did not observe interference in the nitrite test. However, we tested only three samples that were positive for nitrite, so it is difficult to say that vitamin C does not interfere with the nitrite test.


Wondering if you get enough Vitamin C through diet and/or nutrient supplements? VitaChek-C strips have been exclusively created by Riordan Clinic for in vitro measurement of urine Vitamin C. Each bottle contains 50 test strips. Start by testing early in the day before eating or taking nutrients. Then test after breakfast and again in the afternoon. Test a final time right before bed. The test strips are designed to be a fast and simple way to check your nutrient levels of Vitamin C daily so that you can adjust your diet or nutrient regimen accordingly.


Glucose meters are increasingly used in hospitals and home settings. These handheld devices provide instant readings and are therefore, beneficial for glucose-level monitoring in patients with diabetes [1]. Nonetheless, there have been concerns regarding the measurement accuracy of glucose meters. Some substances, such as vitamin C and maltose, are considered responsible for errors in glucose measurements using point-of-care testing glucose meters [1,2,3]. Vitamin C is widely used in the treatment of cancer, viral infections, severe burns, and chronic fatigue syndrome because of the antioxidant effects [4]. Maltose can be upregulated in patients undergoing peritoneal dialysis involving icodextrin as an osmotic agent [3]. High concentrations of vitamin C and maltose in blood can lead to false increase in glucose meter readings, resulting in misdiagnosis of hypoglycemia and potential fatalities [1]. Therefore, there is an urgent need for interference-resistant glucose meters [5]. We evaluated the interference of vitamin C and maltose with glucose readings obtained using the following t
