COVID-19 Antigen Rapid Test Pen (Saliva)

Panbio 2

The Rapid Response COVID-19 Antigen Rapid Test Pen (Saliva) is an in vitro immunoassay. The assay is for the direct and qualitative detection of SARS-CoV-2 viral nucleoprotein antigens from saliva samples through visual interpretation of colour development. This test is intended for professional use only.

Key Benefits:

• First and the only no-spit test dedicated to COVID-19 – Its sponge-like pen tip will collect a sufficient volume of specimen in 2 mins without the need to spit and avoiding uncomfortable nasal/throat swabbing.
• ALL IN ONE – No need to waste time setting up a workstation and handle numerous assay components. All you need is one pen that can be used comfortably in any location.

Test Principle 

Anti-SARS-CoV-2 antibodies are immobilized on the test region of the nitrocellulose membrane. Anti-SARS-CoV-2 antibodies conjugated to coloured particles are immobilized on the conjugated pad. A sample is added to the extraction buffer which is optimized to release the SARS-CoV-2 antigens from specimen. During testing, target antigens, if present in the saliva samples, will be released into the extraction buffer individually packed in the kit. Consequently, the extracted antigens will bind to anti-SARS-CoV-2 antibodies conjugated to coloured particles

As the specimen migrates along the strip by capillary action and interacts with reagents on the membrane, the complex will be captured by the anti-SARS-CoV-2 antibodies at the test region. Excess coloured particles are captured at the internal control zone. The presence of a coloured band in the test region indicates a positive result for the SARS-CoV-2 viral antigens, while its absence indicates a negative result. A coloured band at the control region serves as a procedural control, indicating that the proper volume of specimen has been added and membrane wicking is working.

 

ï¿­ INVBIO saliva alcohol screening test kit detects alcohol presence in saliva. Therefore, directly dipping the strip into alcohol alone will not provide you with an accurate reading.
ï¿­ It is very important that the test be read at exactly two minutes, The result you read 2 minutes after saturation with saliva is the accurate test result.
ï¿­Nothing should be placed into the mouth of the subject for at least 10 minutes prior to saliva collection. This includes food, drink, tobacco products or other materials.

SPECIMEN COLLECTION AND PREPARATION
ï¿­Nothing should be placed into the mouth of the subject for at least 10 minutes prior to saliva collection. This includes food, drink, tobacco products or other materials.
ï¿­ Saliva specimen can be collected in a sputum cup or a clean container, or directly applied to the reaction pad of the test strip.

PROCEDURE:
Open the foil package and remove the test strip.
Saturate the reactive pad by dipping the reaction pad into the saliva specimen collected in a cup, or saturate the reactive pad on the end of stick with saliva in mouth for 10 seconds, shake off the excess saliva.
Immediately start timer and at exactly 2 minutes, compare the reactive pad with the provided colored chart.
Results after more than 2 minutes may be not accurate.

INTERPRETATION OF RESULTS:
­ Negative: Almost no color change by comparing with the background. The negative result indicates that the BAC is less than 0.02%.
­ Positive: A distinct color developed all over the pad. The positive result indicates that the BAC is 0.02% or higher.
­ Invalid: The test should be considered invalid If only the edge of the reactive pad turned color that might be ascribed to insufficient sampling.

 

FLX pyrosequencing analysis of the effects of the brown-algal fermentable polysaccharides alginate and laminaran on rat cecal microbiotas.

FLX pyrosequencing analysis of the effects of the brown-algal fermentable polysaccharides alginate and laminaran on rat cecal microbiotas.

Edible brown algae are used as main meals materials in Far East Asian international locations, significantly in South Korea and Japan. They comprise fermentable dietary fibers, alginic acid (uronic acid polymer) and laminaran (β-1,3-glucan), which can be fermented into natural acids by intestinal micro organism.

To make clear the impact of edible algae on the intestinal setting, the cecal microbiotas of rats fed diets containing no dietary fiber (management) or 2% (wt/wt) sodium alginate or laminaran for two weeks have been analyzed utilizing FLX amplicon pyrosequencing with bar-coded primers focusing on the bacterial 16S rRNA gene. The most considerable phylum in all teams was Firmicutes.

Specifically, Allobaculum was dominant in all food regimen teams. In addition, Bacteroides capillosus (37.1%) was considerable in the alginate group, whereas Clostridium ramosum (3.14%) and Parabacteroides distasonis (1.36%) have been solely detected in the laminaran group. Furthermore, rats fed alginate confirmed simplified microbiota phylotypes in contrast with others. With respect to cecal chemical compounds, laminaran increased cecal natural acid ranges, significantly propionic acid. Alginate elevated complete cecal natural acids.

Cecal putrefactive compounds, comparable to indole, H(2)S, and phenol, have been decreased by each alginate and laminaran. These outcomes point out that edible brown algae can alter the intestinal setting, with fermentation by intestinal microbiota.

Tsunami lung.

We encountered three instances of lung issues attributable to drowning in the current massive tsunami that struck following the Great East Japan Earthquake. All three have been females, and two of them have been outdated aged. All segments of each lungs have been concerned in all the three sufferers, necessitating ICU admission and endotracheal intubation and mechanical air flow. All three died inside 3 weeks.

In no less than two instances, misswallowing of oil was suspected from the options famous at the time of the detection. Sputum tradition for micro organism yielded isolation of Stenotrophomonas maltophilia, Legionella pneumophila, Burkholderia cepacia, and Pseudomonas aeruginosa. The trigger of tsunami lung could also be a mix of chemical induced pneumonia and bacterial pneumonia.
