Product Introduction
- Product Overview: The FOB Tube (Fecal Occult Blood Test Tube) developed by Xiamen Zhizi Industry & Trade Co., Ltd. is a professional medical device tailored for early screening of digestive tract diseases (e.g., gastric cancer, colorectal cancer). It integrates fecal sample collection, preservation, and pre-processing functions, replacing traditional multi-step "sample + reagent" separate operations. Widely used in hospitals, physical examination centers, and primary healthcare institutions, this FOB Tube simplifies the occult blood testing process while ensuring detection accuracy, making it a reliable tool for clinical diagnosis and disease prevention.
- Product Performance: The FOB Tube excels in sample compatibility, stability, and usability. It is fully compatible with mainstream detection platforms (chemiluminescence, immunoturbidimetry), enabling direct loading of fecal samples without matrix interference, ensuring detection accuracy ≥98%. The pre-filled reagent in the tube maintains stability for 18 months at room temperature (2-30℃), eliminating the need for cold chain transportation. Equipped with a precision sampler (0.1-0.2g fixed sampling volume), it reduces operation error to ≤5%, significantly improving test repeatability. Additionally, its humanized packaging design supports efficient laboratory management, adapting to high-volume testing scenarios.
Product Advantages
- Excellent Sample Compatibility for Versatile Detection: The FOB Tube features optimized sample compatibility, seamlessly adapting to multiple mainstream detection platforms in clinical practice, including chemiluminescence and immunoturbidimetry. Unlike ordinary test tubes that require complex sample pre-treatment (e.g., dilution adjustment, impurity removal) to avoid matrix interference, the FOB Tube’s pre-filled buffer solution contains a "matrix modifier" component. This component can neutralize interfering substances in fecal samples (such as bilirubin, bacteria metabolites) within 5 minutes, ensuring direct loading of the treated sample into detection instruments without affecting reagent reaction kinetics. Clinical verification shows that when used with different platforms, the FOB Tube maintains a detection consistency rate of over 95%, eliminating the need for platform-specific tube replacement and reducing laboratory consumable costs.
- Long-Term Stability to Reduce Logistics & Storage Costs: The FOB Tube’s pre-filled reagent adopts a "double-stabilizer system" (including antioxidant and microbial inhibitor), which effectively inhibits reagent degradation and microbial growth at room temperature. Unlike traditional reagents that require -20℃ freezing storage or 2-8℃ cold chain transportation (increasing logistics costs by 30%+), the FOB Tube can be stored at 2-30℃ for up to 18 months, with no significant change in reagent activity. This not only simplifies storage conditions (no need for professional refrigeration equipment) but also lowers transportation costs (compatible with ordinary express delivery). It is particularly suitable for resource-limited areas (e.g., remote rural clinics) that lack cold chain support, ensuring timely supply of testing consumables.
- Standardized Quantitative Sampling for High Repeatability: The FOB Tube is integrated with a precision sampler—either a fixed-volume sampling spoon (0.1g standard) or a calibrated pipette (0.2mL fixed volume)—which is designed to match the tube’s internal structure. During sampling, the sampler can only collect a fixed amount of fecal sample, avoiding the problem of inconsistent sampling volume caused by manual operation (e.g., excessive sampling leading to reagent dilution, insufficient sampling causing false negatives). Through 1000+ repeated tests, the sampling error of the FOB Tube is controlled within ≤5%, while the repeatability of test results (CV value) is improved to ≤3%, far lower than the industry average of 8%. This standardized design ensures that test results from different operators or laboratories are comparable, laying a foundation for accurate clinical diagnosis.
- Eco-Friendly & Humanized Packaging for Efficient Management: The FOB Tube adopts an eco-friendly packaging solution—its tube body uses recyclable medical-grade PP material, and the outer packaging is made of degradable paper-plastic composite material, reducing environmental pollution. In terms of usability, the tube body features a "stackable design" (uniform diameter and height), which saves 40% of storage space compared to irregularly shaped tubes, facilitating warehouse inventory management. The outer packaging clearly marks the batch number, expiration date, and recommended storage conditions, allowing laboratory staff to quickly identify valid products. Moreover, some models of the FOB Tube have a "writable information area" on the tube body, enabling direct marking of patient name, sampling time, and other information with a marker pen, avoiding sample confusion and improving the efficiency of sample tracking.
Product Operation Guide
- Step 1: Unpacking and Preparation: Take out the FOB Tube from the outer packaging, check if the FOB Tube is intact (no cracks, no reagent leakage), and confirm the expiration date. Tear open the sterile packaging of the FOB Tube’s built-in sampler, and put on disposable gloves to avoid sample contamination. Place the FOB Tube on a flat operating table to ensure stable placement during subsequent operations.
- Step 2: Sample Collection: Hold the FOB Tube in one hand, and use the built-in precision sampler to collect fecal samples. Insert the sampler into the middle layer of feces (avoiding the outer layer contaminated by toilet water), and the sampler will automatically collect the fixed-volume sample (0.1g/0.2mL). After collection, insert the sampler back into the FOB Tube, ensuring the sample is fully immersed in the pre-filled reagent.
- Step 3: Sample Mixing and Incubation: Screw the cap of the FOB Tube tightly (rotate until a "click" sound is heard to confirm sealing), and invert the FOB Tube 5-8 times to fully mix the sample and reagent. Place the FOB Tube at room temperature (20-25℃) for 10 minutes to allow the reagent to react with the sample (do not shake violently during incubation to avoid foam affecting detection).
- Step 4: Loading and Detection: After incubation, open the cap of the FOB Tube, and use a pipette to 吸取 100μL of the mixed solution from the FOB Tube. Load the solution into the detection instrument (chemiluminescence/immunoturbidimetry platform) according to the instrument instructions, and record the test results. After use, place the FOB Tube into a medical waste bin for centralized disposal (do not reuse the FOB Tube).
Frequently Asked Questions
Q: Can the FOB Tube be used for samples other than human feces?
A: No, the FOB Tube is specifically designed for human fecal occult blood testing. Its reagent formula and sampler volume are optimized for human fecal samples. Using it for animal feces or other biological samples may lead to inaccurate results due to mismatched matrix components.
Q: What should I do if the reagent in the FOB Tube changes color before use?
A: The normal color of the FOB Tube’s pre-filled reagent is light yellow or colorless. If the reagent turns brown, red, or other abnormal colors before opening, it indicates possible reagent deterioration. Do not use this FOB Tube; please contact our customer service for replacement with a new batch.
Q: Is there a requirement for the time interval between sample collection and detection using the FOB Tube?
A: After sample collection and mixing in the FOB Tube, it is recommended to complete detection within 2 hours at room temperature. If detection is delayed, store the FOB Tube at 2-8℃ for no more than 24 hours. Prolonged storage may cause reagent activity decline, affecting test accuracy.
