When using Chemstrip 7 urine test strips, it's important to be aware of certain safety considerations to ensure accurate results and minimize potential risks:

Chemical Exposure: The reagent pads on Chemstrip 7 contain chemicals that can be harmful if they come into contact with skin or mucous membranes. To prevent irritation or injury, avoid touching the reagent areas directly. If accidental contact occurs, immediately rinse the affected area with plenty of water.

Handling and Storage: Always handle the test strips with clean, dry hands to prevent contamination. Store the strips in their original container, tightly sealed, at room temperature below 30°C (86°F). Do not freeze the strips, as extreme temperatures can affect their performance. Ensure the strips are used before their expiration date to maintain accuracy.

Sample Collection: Use a clean, dry container to collect the urine sample. Test the sample as soon as possible after collection to obtain reliable results. If immediate testing isn't feasible, refrigerate the sample at 2-8°C (36-46°F) and bring it to room temperature before testing. Mix the sample thoroughly prior to testing to ensure consistency.

Interference Factors: Certain substances can interfere with test results. For instance, high concentrations of vitamin C (ascorbic acid) in urine may lead to false-negative readings for glucose and blood. Chemstrip 7 is designed to resist vitamin C interference; however, it's still advisable to be cautious of potential interferences. Additionally, highly colored urine or the presence of certain medications can affect the accuracy of the test.

Environmental Considerations: Chemstrip 7 contains chemicals, including arsenic, known to the State of California to cause cancer. Handle and dispose of the strips according to local regulations to minimize environmental impact.

By adhering to these guidelines, you can ensure the safe and effective use of Chemstrip 7 urine test strips, leading to more accurate and reliable results.

Chemstrip 7 urine test strips are designed to minimize interference from Vitamin C (ascorbic acid), which can otherwise lead to false-negative results for glucose and blood in urine tests. This is achieved through an iodate-impregnated mesh layer that oxidizes ascorbic acid before it reaches the reagent pads.

However, certain substances can still affect the accuracy of Chemstrip 7 results:

• High Specific Gravity (SG): Urine samples with high SG may contain crenated red blood cells that do not lyse upon contact with the reagent pad, potentially leading to false-negative results for blood.

• Formalin: Used as a preservative, formalin can cause false-negative reactions in blood tests.

• Medications: Captopril, a medication for hypertension, and high concentrations of nitrite can decrease the sensitivity of blood detection on the test strips.

• Unmixed Samples: Red blood cells can settle at the bottom of the urine container. Failing to mix the sample thoroughly before testing may result in a falsely decreased reading for blood.

To ensure accurate results with Chemstrip 7, it's important to be aware of these potential interferences and follow proper testing procedures.
