The Advantages Of ELISA Test And Its Application In Disease Viruses Diagnostic

What are the advantages of an ELISA test?

One of the greatest advantages of ELISA tests is the ability to obtain quick and accurate results.  All that is normally required is a simple blood sample that is obtained either through the arm or fingertip of a patient.  The fact that an ELISA kit can test not only for antibodies, but antigens as well, makes it a versatile tool for physicians, laboratories, and medical professionals all over the world.The ELISA tests have also found applications in the food industry in detecting food allergens, such as milk, peanuts, walnuts, almonds, and eggs.  ELISA tests can also be used in toxicology as a screen for certain classes of drugs.  Another advantage of using ELISA test kits is their high sensitivity.  ELISA Tests are favored over other testing options because not only are they more sensitive, but they are more cost effective.  Even more striking, is the applicability of the ELISA tests as convenient and easy-to-use HIV ELISA testing devices.


ELISA Tests and HIV ELISA Tests

Because ELISA tests can be performed to evaluate either the presence of antigen or the presence of antibody in a sample, it is a useful tool for determining serum antibody concentrations, such as with HIV ELISA tests.  The HIV ELISA test is usually the first one used to detect infection with HIV virus.  If antibodies to the HIV virus are present, or positive, the test is usually repeated to confirm the diagnosis.  If the ELISA test is negative, other tests are not usually needed.  The ELISA test generally has a low chance of having a false result after the first few weeks of HIV infection.  The specificity and high sensitivity of the HIV ELISA Test make it a widely acceptable kind of ELISA test since it is able to detect all the possible HIV infections.  The HIV ELISA Test was the first screening test widely used for the HIV virus because of its high sensitivity.  Use of the HIV ELISA test kit, in relation to HIV virus detection, can be intended both for screening of blood donors or as an aid for the diagnosis of clinical conditions related to infection with HIV virus.

Testing for Herpes Simplex 1 & 2 | Herpes Simplex Elisa kits

Herpes is a very serious viral disease. This disease is caused by both the Herpes Simplex virus type 1, also known as HSV-1, and type 2, also known as HSV-2. People often get herpes on the lips, which is the most common form of the infection, but one can also catch genital, ocular, and neonatal herpes. Using ELISA kits from Diagnostic Automation / Cortez Diagnostics, Inc., you can figure out if you or your patients are suffering from this disease. We offer the following kits:

Check out our selection and choose the kit that fits your needs. Additional herpes kits are available. The team at Diagnostic Automation / Cortez Diagnostics, Inc., work hard to make sure we provide you with the best and most affordable ELISA kits on the market. 



Los Angeles based Diagnostic Automation/Cortez Diagnostics, Inc., a leading provider of Hepatitis Test Kits, offers top quality HBsAg ELISA kits at competitive prices and in a timely manner.  Our company is committed to offering the best quality HBsAg Elisa Kits worldwideThese convenient and easy-to-use HBsAg Elisa Kits (Hepatitis B ELISA Kits) can immediately detect any Hepatitis B surface antigen infection.


HBsAg ELISA kits and other Hepatitis ELISA test kits, also known as HBsAg EIA kits and HBV EIA kits, are Enzyme-Linked Immunosorbent Assays for qualitative detection of Hepatitis B viruses in human serum or plasma samples. Hepatitis B ELISA kits (HBsAg Elisa Kits) are intended for screening test of blood donors and as an aid for diagnosis.


Hepatitis B virus (HBV) is transmitted through infected body fluids, including blood, semen, and vaginal fluids (including menstrual blood).  It can also be transmitted from a pregnant woman to her child at or near the time of birth.  There are several different Hepatitis ELISA tests kits to detect the hepatitis B virus.  One of the most common Hepatitis ELISA test kits is the Hepatitis B surface antigen (HBsAg) ELISA Test Kit.

The Hepatitis B Test checks for substances in the blood that show whether a hepatitis B infection is active or has occurred in the past.  The Hepatitis ELISA Test Kit (HBsAg ELISA Kit) looks for different signs of infection (markers).  For example, Antigens are markers (HBsAg) made by bacteria or viruses, so the presence of hepatitis B antigens means that the virus is in the body.  Hepatitis B surface antigen (HBsAg) is the earliest sign of an active hepatitis B infection.  This antigen may be present before symptoms of an HBV infection are present.  If this antigen is present for more than 6 months, then there is probably a chronic long-term HBV infection.  This means the Hepatitis B virus can be spread to others through a person’s life.  On the other hand, antibodies (HBsAb) are proteins produced by the body to fight infection.  The presence of Hepatitis B antibodies means that there has been an exposure to the hepatitis B virus, whether from a long past exposure or a current infection.  Genetic material (DNA) of the hepatitis B virus shows that the virus is in the body.  The amount of DNA can help determine how severe the hepatitis infection is and how easily the HBV infection can be spread.  It is important to identify the type of hepatitis virus causing the infection to prevent its spread and choose the proper treatment.



For detection of HBsAg, this quick and accurate Hepatitis ELISA test kit uses antibody “sandwich” ELISA method in which, polystyrene microwell strips are pre-coated with monoclonal antibodies specific to HBsAg virus.   Patient’s serum or plasma sample is added to the microwell together with a second antibody conjugated the enzyme horseradish peroxidase (the HRP-Conjugate) and directed against a different epitope of HBsAg.  During incubation period of this HBsAg Elisa Test, the specific immunocomplex formed in case of presence of HBsAg (Hepatitis B virus) in the sample, is captured on the solid phase. After washing to remove sample serum proteins and unbound HRPconjugate, chromogen solutions containing tetramethyl-benzidine (TMB) and urea peroxide are added to the wells. In presence of the antibody-antigen-antibody(HRP) “sandwich” immunocomplex, the colorless chromogens are hydrolyzed by the bound HRP-conjugate to a blue-colored product. The blue color turns yellow after stopping the reaction with sulfuric acid. The amount of color intensity can be measured and it is proportional to the amount of antigen captured in the wells, and to its amount in the sample respectively. Wells containing samples negative for the HBsAg virus remain colorless.

Hepatitis B virus (HBV) is an enveloped, double-stranded DNA virus belonging to the Hepadnaviridae family and is recognized as the major cause of blood transmitted hepatitis together with hepatitis C virus (HCV).   HBV virus infection induces a spectrum of clinical manifestations ranging from mild, inapparent disease to fulminant hepatitis, severe chronic liver diseases, which in some cases can lead to cirrhosis and carcinoma of the liver. Classification of a hepatitis B virus infection on this Hepatitis ELISA test requires the identification of several serological markers expressed during three phases (incubation, acute and convalescent) of the infection.




Diagnostic Automation/Cortez Diagnostics, Inc. also offers the best quality HbsAg Rapid Test (Strip) RapiDip™ InstaTest to detect Hepatitis B virus.  The One Step Strip Style HBsAg Test (Hepatitis Rapid Test) is a rapid direct binding test for the visual detection of hepatitis B surface antigen (HBsAg) in serum as an aid in the diagnosis of hepatitis B infection.  This One Step HBsAg Test (Hepatitis Rapid Test) is based on the principle of sandwich immunoassay for determination of the HBsAg virus in serum.  Monoclonal and polyclonal antibodies are employed to identify the HBsAg (Hepatitis B virus) specifically. This One Step Hepatitis B test is very sensitive and only takes about 10-20 minutes for the result to be read. Test results are read visually without any instrument.
