Medomics – SARS-CoV-2

Faisal Zafar — Fri, 11 Feb 2022 11:44:36 +0000

Medomics The SARS-CoV-2 Antigen Test Kit. Through the receptor-binding domain (RBD) of the spike protein, the virus infects human cells.

Influenza A/B infection mechanism

The hemagglutinin on the virus’s surface binds to the corresponding receptors on the respiratory epithelium, and simultaneously adsorbs on the epithelium of the host.

Test Principle

SARS-CoV-2 Antigen Test Strip

Colloidal gold-labeled anti-SARS-CoV-2 antibody is sprayed on the conjugation pad and Use another anti-SARS-COV-2 antibody and one quality control antibody to fix on the NC membrane respectively as T line and C line.

When the appropriate test sample treated with lysis buffer is added to the sample well of the test strip because of this the sample will move forward along the test strip by capillary action.

Antigen of the SARS-CoV-2 virus will attach to the colloidal gold-labeled anti-SARS-CoV-2 antibody if it is higher than the limit of detection.

In addition, the sample does not contain SARS-CoV-2 antigen or the concentration is lower than the limit of detection, so a negative result is displayed and only a red C line appears.

Testing Methods for SARS-Cov-2 SARS-Cov-2

Medomics – SARS-CoV-2 Antigen Test Kit (LFIA) determines if someone is infected by detecting the presence of viral material.

How does the virus infect the cell

For the virus to invade the human cells, it needs to attach to the ACE2 receptor with the receptor binding domain (RBD) of the Spike protein.
Colloidal gold-labeled anti-SARS-CoV-2 antibody and quality control antibody are sprayed on conjugation pad.
Test line is fixed with anti-SARS-CoV-2 antibody for detecting the novel coronavirus and the quality control antibody is fixed on the Control line.

Advantage of Medomics – SARS-CoV-2 Antigen Test Kit (LFIA)

It is easy to use
It show accurate result
Show result in just 15 minutes

Tests to detect SARS-CoV-2 infection

There are several types of tests used to detect SARS-CoV-2,1 and their performance characteristics vary.

Tests can provide results quickly (within minutes); others require processing time.
Several tests require specialized training in a laboratory, while others can be performed at the point of care or at home.
It is possible for some tests to identify SARS-CoV-2 without a false-negative result; other tests can identify SARS-CoV-2 without a false-positive result; and some tests can identify both.
Because some tests are less expensive and easier to perform, and supplies are readily available, they can be performed frequently.

Healgen Rapid Test Cassette For COVID-19 – 1 Piece

Faisal Zafar — Fri, 11 Feb 2022 06:53:49 +0000

Helegen Rapid

The COVID-19 IgG/IgM (Whole Blood/Serum/Plasma) Helegen Rapid Test Cassette For COVID-19 utilizes lateral flow technology for the qualitative, differential detection of both anti-SARS-CoV-2 IgM and IgG antibodies. In general, antibodies can be detected 1-3 weeks after infection. This test is intended to screen patients for SARS-CoV-2 antibodies. Coronaviruses are enveloped RNA viruses that are distributed broadly among humans, other mammals, and birds that cause respiratory, enteric, hepatic, and neurologic diseases. Four viruses – 229E, OC43, NL63, and HKU1 are prevalent and typically cause common cold symptoms in immunocompromised individuals. Three other strains SARS-CoV, MERS-CoV, and SARS-CoV-2 (COVID-19) can be transmitted from non-human vertebrates to humans.

Warning:-

This product has not been FDA cleared or approved, but has been authorized for emergency use by FDA under a EUA for use by authorized laboratories.
This product has been authorized only for detecting the presence of IgG and IgM antibodies to SARS-CoV-2, not for any other viruses or pathogens.
The emergency use of this product is only authorized for the duration of the declaration that circumstances exist justifying the authorization of emergency use of in vitro diagnostics for the detection and/or diagnosis of COVID-19 under Section 564(b)(1) of the Federal Food, Drug, and Cosmetic Act, 21 U.S.C. § 360bbb-3(b)(1) unless the declaration is terminated or authorization is revoked sooner.
This product is intended for professional use and not for home use.
Not for the screening of donated blood.

Instructions for Use

1. Remove the test cassette from the sealed foil pouch and use it as soon as possible.
2. Lay the device on a flat surface and add specimen (see specific instructions for each specimen type below):
a. For Serum or Plasma Specimen: With the plastic dropper provided, draw serum/plasma specimen to exceed the specimen line, as shown in the diagram below. Hold the dropper vertically and transfer the drawn serum/plasma specimen into the sample well (S). Immediately add 2 drops (about 80 μL) of sample buffer to the buffer well (B) ensuring that the buffer vial tip does not touch the sample. Avoid air bubbles.
b. For Whole Blood Specimen: Hold the plastic dropper vertically and transfer 1 drop of whole blood (about 10 μL) to the sample well (S) of the test device. Immediately add 2 drops (about 80 μL) of sample buffer to the buffer well (B) ensuring that the buffer vial tip does not touch the sample. Avoid air bubbles.
3. Wait for the control line (C) to change from blue to a red color. If, after 2 minutes, the sample has not moved across the test window or if blood is still present in the sample well (S), add 1 additional drop of sample buffer to the buffer well (B).
4. The results should be read in 10 minutes. Do not interpret the result after 15 minutes.
