Overview

The follicle-stimulating hormone (FSH) test kit is an in-vitro diagnostic (IVD) that qualitatively measures FSH in urine to help women monitor fertility status, perimenopausal transition, or ovarian reserve at home or in clinic. Supplied by GIVE LIFE TIME LIMITED under the Magewell brand, the kit uses colloidal gold immunochromatography in a five-test box that also includes a urine cup. From a regulatory standpoint the product must be handled as a regulated IVD: distributors need to confirm the intended-use labeling, the validity period, and the storage conditions before the kit enters a market, because mislabeled fertility tests create both compliance and consumer-safety exposure.

How It Works

The strip applies a double-antibody sandwich format. Colloidal gold conjugated to an anti-FSH antibody sits at the sample end; when urine is applied, FSH antigen binds the conjugate and the complex migrates along the nitrocellulose membrane. The test zone is coated with a second anti-FSH monoclonal antibody that captures the complex and forms a visible band when FSH is present, while the control zone is coated with goat anti-mouse IgG that must capture conjugate to validate the run. A positive sample shows both test and control bands, whereas a negative sample shows only the control band. Results are read one to five minutes after immersion, within a ten-minute window.

Indications

The kit is intended for women who have tried unsuccessfully to conceive, those approaching age 50, people with irregular lifestyles, and those planning a later second child, as a self-referential check of urinary FSH trends. It is an aid, not a diagnosis, and the final interpretation should rest with a clinician. Distributors should present it as a qualitative screening device and avoid therapeutic or diagnostic claims that would reclassify the product under stricter medical-device rules.

Dosage & Administration

Collect a fresh urine sample in the supplied cup at a consistent daily time without excessive pre-test hydration, then dip the strip arrow-end into the urine for one to five seconds without exceeding the MAX line. Lay the strip flat and read once the control line appears, within one to five minutes and no later than ten minutes. Use each strip once and discard after reading.

Storage & Sourcing

Store unopened kits at 2 to 8 degrees C for up to 72 hours if testing is delayed, or aliquot and freeze at minus 20 degrees C for long-term holding not exceeding three months, avoiding repeated freeze-thaw. The box measures 14 by 7.6 by 2.3 cm and weighs 29 g, with a two-year shelf life from manufacture. GIVE LIFE TIME LIMITED sets a minimum order of 5,000 units; buyers should verify the five-test presentation, the 2 to 8 degrees C short-term range, and the in-vitro labeling before bulk import. Batch numbers support lot traceability through the cold chain.

FAQ

Q: What should a missing control band indicate to the user?
A: The control zone must capture conjugate for the run to be valid, so a missing control band means the strip failed and the test should be repeated.

Q: How should distributors manage the two-year shelf life?
A: Keep stock at the stated 2 to 8 degrees C short-term range, rotate by batch expiry, and avoid freeze-thaw cycles that can degrade the conjugates.

Q: Is this kit a diagnostic device on its own?
A: No, it is a qualitative in-vitro screening aid; distributors must label it accordingly and direct users to clinical confirmation for final interpretation.
