The Rapid Antigen Test for African Swine Fever (ASF) is a chromatographic immunoassay intended for the visual qualitative detection or machine read quantitative detection of antigens to African swine fever virus (ASFV) in pig oral samples. ASF is a highly contagious viral disease of domestic and wild pigs including domesticated swine (pigs), wild boars, feral swine, warthogs, bush pigs, and giant forest hogs. It is caused by the ASFV, a large DNA virus of the Asfarviridae family. ASF is a notifiable disease to the World Organisation for Animal Health (OIE). ASF poses a significant threat to the global swine industry. Timely and accurate detection of ASF is essential for effective disease management and containment.
ASF is characterized by a range of clinical symptoms, including high fever, loss of appetite, hemorrhages, and high mortality rates. ASF can be transmitted between pigs through direct contact with infected pigs or their bodily fluids, or through indirect contact with contaminated objects. The virus can also be transmitted by ticks. Currently, there is no specific treatment or vaccine available for ASF. Infected pigs must be culled to prevent the spread of the virus. Preventative measures include biosecurity to prevent the introduction of the virus into a herd, and surveillance measures to detect the virus early. ASF is not a zoonotic disease, meaning that it cannot be transmitted from pigs to humans.
This user-friendly and reliable ASF Rapid Antigen Test has been designed to assist veterinarians, animal health professionals, and farmers in quickly identifying ASF-infected pigs, allowing for prompt action to limit the spread of the virus and minimize its economic impact.
This test utilizes a lateral flow immunoassay, employing dye-labeled particles that bind to ASF antigens in the sample. A nitrocellulose membrane is immobilized with a monoclonal antibody against the ASF antigen. Another anti-ASF Ag monoclonal antibody is conjugated to colloidal gold particles. This conjugate is placed on a polyester pad as a conjugate pad. When the test is in assay buffer containing specimens, the solubilized conjugate migrates with the sample by passive diffusion and both the conjugate and sample come into contact with the anti-ASF antibody that it absorbed onto the nitrocellulose. The appearance of a colored line on the test strip indicates the presence of ASFV antigens.
Positive results do not rule out bacterial infection or co-infection with other viruses. Negative results should be considered in the context of recent exposures, history and the presence of clinical signs and symptoms. The Rapid Antigen Test for ASF is intended for use by medical professionals or trained operators who are proficient in performing tests and trained clinical laboratory personnel.

Materials Required but not Provided:
Storage And Disposal
The product should be stored at 2-30°C. Do not freeze or overheat the test kit or kit reagents. Kit contents are stable until the expiration date printed on each test kit. The indicators must be kept in the foil pouch until use. Dispose of used contents in accordance with federal, state, and local requirements.
Before use, check the expiration date of the packaging. If the kit is past its expiration date, do not use. Confirm that all components needed are in the kit.
The SWAC (Sterile Wood Abrasive Collector) is used to collect an oral fluid sample. This is a non-invasive method that collects a sample of saliva from the animal’s mouth using the SWAC. Oral fluid samples are easy to collect and can be used on animals of all ages.
When collecting samples, it is important to use sterile equipment and to avoid contaminating the sample. Samples should be labeled with the animal’s identification number and the date and time of collection. Samples should be transported to the laboratory as soon as possible for testing. Appropriate PPE should be worn when collecting samples from animals, and caution should be used if an animal is sick or aggressive.
Inadequate or inappropriate sample collection, storage, and transport may yield false test results. The training in specimen collection is highly recommended because of the importance of specimen quality.
Obtain the sterile SWAC. Make sure the SWAC head does not touch anything until sample collection.
Insert the SWAC into the mouth of the animal being tested. Keep the SWAC near the cheek in the mouth. Rotate the SWAC 5 times to collect saliva.
Stand up the Spacket, and tear it open. Be careful not to spill the liquid reagent inside.
Put the SWAC into the Spacket. Roll the swab 5 times. Leave the SWAC in the Spacket for 1 minute before inserting the test indicator.
While the SWAC remains in the Spacket, place the test indicator into the Spacket with sample pad going down. Leave the test indicator in the Spacket for 10 minutes. Use the assaya timerDx to keep track of the test time.
Take out the test indicator and read the result at 10 minutes. Do not read the result after 20 minutes. The test indicator may also be read by the intelligent analyzer eXpress (iaX-2101) after 10 minutes.
Positive Indicator Line Legend
At 10 minutes, the appearance of the Control Line and Test Line on the Test Indicator, indicates a positive result for the presence of antigens for ASFV. Positive test results only mean antigens for ASFV exist in the specimen
At 10 minutes, the appearance of only Control Line indicates a negative result for the presence of antigens for ASFV.
If at 10 minutes, the Control Line does not appear, even if a Test Line appears in the indicator, the result is considered invalid. If the test is invalid, a new test should be performed with a new patient sample and a new Test Indicator.
Two internal procedural controls are needed to confirm correct assay procedure and active kit components. One of two is a line appearing in the “Control Line” area in every run of the test to assess validity of the test. Another one is a clear background serving as an internal negative control. The background color should be white and not interfere with the reading of the test result. If the background color interferes with the reading, it is recommended to repeat the test.

Warnings & Precautions
The RDT for ASF has been evaluated for sensitivity and specificity using a panel of known ASF-positive and ASF-negative pig oral samples. The test was found to have a sensitivity of 99% and a specificity of 98%.
