TEST PROCEDURE
Allow the rapid test, specimen, buffer, and/or controls to equilibrate to room temperature (15-30°C) prior to testing.
- Bring the pouch to room temperature before opening. Remove the rapid test cassette from the sealed pouch and use it as soon as possible.
- Place the test device on a clean and horizontal surface. Reverse the specimen collection tube, extrude 3 drops of the prepared specimen into the specimen well (S) of the test cassette and start the timer.
- Wait for the colored line(s) to appear. Read results at 8-10 minutes. Do not interpret the result after 15 minutes.
INTERPRETATION OF RESULTS
POSITIVE: Two colored bands appear on the membrane. One band appears in the control region (C) and another band appears in the test region (T).
NEGATIVE: Only one colored band appears in the control region (C). No apparent colored band appears in the test region (T).
INVALID: Control band fails to appear.

Relative Sensitivity: 97.92% (95%CI: 92.68%~99.75%)
Relative Specificity: 98.00% (95%CI:94.27%~99.59%)
Accuracy: 97.97% (95%CI:95.32%~99.34%)
Cross-reactivity
No cross reaction was observed when samples enriched with the following respiratory symptoms relative pathogens: Influenza A, Influenza B, SARS-COV2, Human coronavirus (229E, HKU1, OC43 and NL63), Parainfluenza virus (type 1-4), Mycoplasma pneumoniae, adenovirus, Neisseria meningitidis, mumps virus, Staphylococcus aureus, Streptococcus pneumoniae.
Interfering Substances:
No interference was observed to the test strip, with the following compounds: Alpha-interferon, purified Mucin, whole blood, budesonide nasal spray, one, Oxymetazoline, HAMA, Fluticason propionate.
Precision (Repeatability & Reproducibility)
Intra-Assay
Within-run precision has been determined by using 15 replicates of three specimens: a negative, a weak positive and a positive standard. The specimens were correctly identified >99% of the time.
Inter-Assay
Between-run precision has been determined by 15 independent assays on the same two specimens: a negative, a weak positive and a positive standard. Three different lots of the Respiratory Syncytial Virus Antigen Rapid Test have been tested using these specimens. The specimens were correctly identified >99% of the time.
COMPANY PROFILE
Hangzhou lmmuno Biotech Co., Ltd is the original organization in lmmuno Group, which has engaged in this industry for more than 10 years. The team of Hangzhou lmmuno Biotech has developed a series of proteins and rapid test kits for the in vitro diagnostic industry in early stage.In the past few years we focused on the human medical diagnostic field which mainly cover the following directions: rapid tests for vector-borne diseases(VBDs), rapid tests for sexually transmitted diseases (STDs), rapid tests for respiratory system diseases, rapid tests for digestive system diseases and rapid test for drug of abuse. For now, we are paying more attention to the diagnosis of neglected tropical diseases (NTDs). With strong R&D ability we are capable to develop and produce test kits for customers in a short time, and our product quality is ahead of similar products in the market.
