VITACHECK-C strips provide a test for vitamin C, or ascorbic acid, in urine.\u003c\/div\u003e\\r\\n\u003cdiv class='\\\"pad10\\\"' style='\\\"margin:' baseline sans arial sans-serif\u003e\u003c\/div\u003e\\r\\n\u003cdiv class='\\\"pad10\\\"' style='\\\"margin:' baseline sans arial sans-serif\u003eVITACHECK-C strips are packaged along with a drying agent (desiccant) in a plastic bottle with a twist-off cap. Each strip is stable and ready to use upon removal from the bottle. The entire reagent strip is disposable. Results are obtained by direct comparison of the test strip with the color blocks printed on the bottle label.

The presence of vitamin C (ascorbic acid) in urine causes the color of the test area to change from green to light yellow.\u003c\/div\u003e\\r\\n\u003cdiv class='\\\"pad10\\\"' style='\\\"margin:' baseline sans arial sans-serif\u003e\u003c\/div\u003e\\r\\n\u003cdiv class='\\\"pad10\\\"' style='\\\"margin:' baseline sans arial sans-serif\u003e\u003cstrong style='\\\"margin:' baseline\u003eINGREDIENTS:\u003c\/strong\u003e\u003c\/div\u003e\\r\\n\u003cdiv class='\\\"pad10\\\"' style='\\\"margin:' baseline sans arial sans-serif\u003e\n\u003cb style='\\\"margin:' baseline\u003eREAGENTS \u003c\/b\u003e(Based on dried weight at time of impregnation)\\r\\n5.8% w\/w ferric chloride\\r\\n4.9% w\/w DTPA\\r\\n1.2% dipyridyl\\r\\n89.1% w\/w buffer and non reactive ingredients\u003c\/div\u003e\\r\\n\u003cdiv id='\\\"list_ingredients\\\"' class='\\\"pad10\\\"' style='\\\"margin:' baseline sans arial sans-serif\u003e\\r\\n\u003cp style='\\\"margin-bottom:' baseline\u003e\u003cb style='\\\"margin:' baseline\u003eWARNING AND PRECAUTIONS:\u003c\/b\u003e\\r\\nVITACHECK-C® strips are for in vitro use only. Do not touch test reagent area of the strip.\u003c\/p\u003e\\r\\n\u003cp style='\\\"margin-bottom:' baseline\u003e\u003cb style='\\\"margin:' baseline\u003eSTORAGE\u003c\/b\u003e\\r\\nStore at room temperature between 15°C – 30°C (59°F – 86°F) and out of direct sunlight. Do not use after expiration date listed on the bottle or box.\u003c\/p\u003e\\r\\n\u003cp style='\\\"margin-bottom:' baseline\u003e\u003cb style='\\\"margin:' baseline\u003eRECOMMENDED HANDLING PROCEDURES\u003c\/b\u003e\\r\\nAll unused strips must remain in the original bottle. Transfer to any container may cause reagent strips to deteriorate and become nonreactive. Do not remove desiccant from bottle. Do not open container until ready to use. Opened bottles should be used within 3 months after first opening.\u003c\/p\u003e\\r\\n\u003cp style='\\\"margin-bottom:' baseline\u003e\u003cb style='\\\"margin:' baseline\u003eTEST PROCEDURE\u003c\/b\u003e\\r\\n1. Remove from the bottle only enough strips for immediate use and replace cap tightly.\\r\\n2. Collect specimen in a clean container. Dip the reagent pad of the strip in a fresh, well mixed urine specimen. Remove the strip immediately.\\r\\n3. While removing, drag the edge of the strip against the top rim of the urine container to remove excess urine. Blot the lengthwise edge of the strip (NOT the reagent pad) on an absorbent paper towel, napkin, etc.\\r\\n4. After 30 seconds, compare the reagent pad to the color blocks on the chart on the bottle. Proper read time and good light are critical for optimal results. Hold the strip and the bottle horizontal with the pad close to the color chart.\u003c\/p\u003e\\r\\n\u003cp style='\\\"margin-bottom:' baseline\u003e\u003cb style='\\\"margin:' baseline\u003eRESULTS\u003c\/b\u003e\\r\\nResults are determined visually by direct comparison of the reacted pad area with the color blocks printed on the bottle label. The color blocks represent the approximate amount of vitamin C (ascorbic acid) in the urine.\u003c\/p\u003e\\r\\n\u003cp style='\\\"margin-bottom:' baseline\u003e\u003cb style='\\\"margin:' baseline\u003eLIMITATIONS OF THE PROCEDURE\u003c\/b\u003e\\r\\nComparison to the color chart for these vitamin C test strips is dependent on the interpretation of the individual. The person reading the results must have normal color vision.\u003c\/p\u003e\\r\\n\u003cp style='\\\"margin-bottom:' baseline\u003e\u003cb style='\\\"margin:' baseline\u003eEXPECTED VALUES\u003c\/b\u003e\\r\\nThe daily average urinary output of vitamin C (ascorbic acid) is 20-30 mg\/day but varies with intake and the physiological and psychological stress of the individual.\u003c\/p\u003e\\r\\n\u003cp style='\\\"margin-bottom:' baseline\u003e\u003cb style='\\\"margin:' baseline\u003eSPECIFIC PERFORMANCE CHARACTERISTICS VITACHECK-C® \u003c\/b\u003ehas been developed to be specific for the measurement of vitamin C (ascorbic acid) in the urine. The performance has been checked in the laboratory and in clinical studies. This test can detect vitamin C (ascorbic acid) as low as 10 mg.\/d1.\u003c\/p\u003e\\r\\n\u003cp style='\\\"margin-bottom:' baseline\u003e\u003cb style='\\\"margin:' baseline\u003eBIBLIOGRAPHY\u003c\/b\u003e\\r\\n1.
