    Description | See Ingredients

    VitaCheck-C Reagent Strips For in Vitro Measurement of Urine Vitamin C (Ascorbic Acid) from Teco Diagnostics are firm plastic strips to which a reagent area is affixed. VITACHECK-C strips provide a test for vitamin C, or ascorbic acid, in urine.

    VITACHECK-C strips are packaged along with a drying agent (dessicant) 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. No calculations or laboratory instruments are required.

    TEST PRINCIPLE
    VITAMIN C (Ascorbic Acid): This test is based on a complex chelating agent with a poly-valent metal ion in its higher state and an indicator dye that reacts with the metal ion in its lower state. The presence of vitamin C (ascorbic acid) in urine causes the color of the test area to change from green to light yellow.

    REAGENTS (Based on dried weight at time of impregnation)
    5.8% w/w ferric chloride
    4.9% w/w DTPA
    1.2% dipyridyl
    89.1% w/w buffer and non reactive ingredients

    WARNING AND PRECAUTIONS:
    VITACHECK-C® strips are for in vitro use only. Do not touch test reagent area of the strip.

    STORAGE
    Store 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.

    RECOMMENDED HANDLING PROCEDURES
    All 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.

    TEST PROCEDURE
    1. Remove from the bottle only enough strips for immediate use and replace cap tightly.
    2. Collect specimen in a clean container. Dip the reagent pad of the strip in a fresh, well mixed urine specimen. Remove the strip immediately.
    3. 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.
    4. 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.

    RESULTS
    Results 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.

    LIMITATIONS OF THE PROCEDURE
    Comparison to the color chart is dependent on the interpretation of the individual. The person reading the results must have normal color vision.

    EXPECTED VALUES
    The 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.

    SPECIFIC PERFORMANCE CHARACTERISTICS VITACHECK-C® has 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.

    Great for checking vitamin c status
    By Normalina from Florida on 05/22/2014
    Pros: Convenient to use
    Cons: none
    Recommended: Yes
    It is good to know the status of vit c level. Sometimes body uses more depending on inflammation in one's body such as sore muscles, arthritic pain, viral or bacterial level. It makes it easier to keep track so you can be protected.

    This is how you know if you have a C problem
    By Dave from Silicon Valley on 04/03/2014
    Pros: see your Vitamin C status
    Recommended: Yes
    Some rare people do fine with minimal C intake. Others need 10 or more grams per day. If you are in the latter group, you are at a lot of risk. Use VitaChek C For in Vitro Measurement of Urine Vitamin C to find out.

    Good Gage for Those Taking Lypospheric C
    By Armstead from California on 05/24/2012
    Pros: Easy to use/read
    Recommended: Yes
    I'm taking high-dose vitamin C using Lypo-Spheric Vitamin C and I wanted to know the correct dosage for my system. Vitacheck helped me reduce the dosage confidently as well as the expense.
