Overview

The fecal occult blood test (FOBT) detects hidden blood in stool that is invisible to the eye, an early signal that distributors and clinics use to screen populations at higher digestive-tract risk. The colloidal gold card from GIVE LIFE TIME LIMITED performs this detection through a single-step immunochromatographic strip rather than a lab-based chemical reaction, which is why it suits pharmacy, community-health, and at-home distribution. The mechanism angle matters for buyers because the test reliability depends on antibody specificity and clear line interpretation, not on a color-change chemical. Wholesalers who explain the principle credibly reduce returned-stock complaints and support correct end-user instruction.

How It Works

Each card embeds colloidal gold particles conjugated to anti-hemoglobin antibodies on a pad at the sample end. When a prepared stool extract is added, any hemoglobin present binds the conjugated antibody and the complex migrates by capillary action along a nitrocellulose membrane. A second anti-hemoglobin antibody immobilized in the test zone captures the complex, producing a visible colored band whose appearance confirms a positive occult-blood result. A separate control zone binds conjugate regardless of sample, so a control line must appear for the test to be valid. The whole read completes within one to five minutes as the liquid front travels the strip.

Indications

This test is positioned for adults in higher-risk groups: people with long-term constipation, diabetes, smoking or heavy drinking habits, a family history of bowel cancer, a preference for spicy or very hot food, and older consumers generally. It is a screening aid, not a diagnostic device, and a positive result should route the user to colonoscopy or clinical confirmation. Distributors should keep indication copy aligned with in-vitro screening language so the product is not marketed as a treatment or cure.

Dosage & Administration

Collect a fresh stool sample the same day using the sampling stick at several points, mix it into the provided container, then transfer two to five drops to the sample window after a two-minute wait. Read the result between one and five minutes. If testing cannot happen immediately, hold the prepared specimen at 2 to 8 degrees C and complete within 48 hours; let it equilibrate to 10 to 30 degrees C before use.

Storage & Sourcing

Each card is packed one serving per box, measuring 7 by 2.4 by 0.6 cm and weighing 5.4 g, with outer packaging 14 by 7.5 by 2.3 cm at 31 g. Store between 4 degrees C and 30 degrees C and respect the 24-month validity. GIVE LIFE TIME LIMITED sets a minimum order of 5,000 units, and buyers should confirm the single-test presentation and ambient storage range before committing pallet-scale volume. Lot-level expiry printing supports first-expiry-first-out rotation in distribution.

FAQ

Q: Why must the control line appear for a valid result?
A: The control zone captures conjugate independent of the sample, so its band proves the strip wicked correctly; without it the test is invalid.

Q: How quickly should the result be read?
A: Interpret the bands one to five minutes after adding the sample, because lines can fade or appear late and mislead the reader.

Q: Can the card replace a colonoscopy?
A: No, it is a screening aid that flags hidden blood; a positive result must be followed by clinical examination such as colonoscopy.
