An abnormal Serology Test

medic-563425_1280Detection of antibodies from serological testing can be used to either diagnose an active or previous infection, or to determine if you are immune to reinfection by an organism. As the disease gets worse, more antibodies will be present. If a disease is suspected, the test may need to be repeated 10 days to 2 weeks after the first test.

If antibodies are found, you may:
Have a current infection.
Have been infected in the past.
Have immunity to a certain organism and are unlikely to become sick.

Some of the different diseases that can be detected include:
Human immunodeficiency virus (HIV)
Fungal infection
Viral hepatitis (various types)

Additional conditions under which the test may be performed:
Amebic liver abscess
Fifth disease
Fungal arthritis
Meningitis, cryptococcal
Meningitis, H. influenza
Meningitis, meningococcal
Viral arthritis

The Purpose of Serology Testing

laboratory-313867_1920A serology blood test is performed to detect and measure the levels of antibodies as a result of exposure to a particular bacteria or virus. When a person is exposed to bacteria or viruses (antigens), their body’s immune system produces specific antibodies against the organism. Antibody levels help physicians determine whether an infection occurred recently or years ago.

There are several types of serological tests that can effectively detect such antibodies. There are also several serology techniques that can be used depending on the antibodies being studied. These include: ELISA, agglutination, precipitation, complement-fixation, and fluorescent antibodies.

ELISA, or enzyme-linked immunosorbent assay, is a test that uses antibodies and color change to identify a substance. ELISA is a popular format of “wet-lab” type analytic biochemistry assay that uses a solid-phase enzyme immunoassay (EIA) to detect the presence of a substance, usually an antigen, in a liquid sample or wet sample.

Serological testing is particularly helpful in the diagnosis of viral diseases such influenza and measles, as well as of infectious diseases like mononucleosis and rheumatoid arthritis.

What Are Serology Tests?

A serology blood test is performed to detect and measure the levels of antibodies as a result of exposure to a particular bacteria or virus. When a person is exposed to bacteria or viruses (antigens), their body’s immune system produces specific antibodies against the organism.

Different types of serologic tests can diagnose various disease conditions; however, serology tests have one thing in common: they all focus on proteins made by the immune system. This vital body system helps keep you healthy by destroying foreign invaders that can make you ill.

The immune system defends against antigens by producing antibodies. These antibodies are particles that attach to the antigens and deactivate them. When your doctor tests your blood, they can identify the type of antibodies and antigens that are in your blood sample and identify the type of infection you have.

Your body produces antibodies in response to antigens. If testing shows no antibodies, it indicates you don’t have a current or past infection. Results that show there are no antibodies in the blood sample are normal. Antibodies in the blood sample often mean you’ve had an immune system response to a specific antigen from either a current or a past exposure to a disease or foreign protein.

What Is Mononucleosis?

Mononucleosis, or Mono, is also known as the “kissing disease”. Mono usually is caused by the Epstein-Barr virus (EBV). This virus is passed from person to person through saliva. However, it can be passed on by ways other than kissing, such as sneezing, sharing drinks or utensils. Here are some symptoms of Mono is most adults and children.mono

  • Sore throat
  • Very high fever
  • Swollen lymph nodes / tonsils
  • Fatigue (general weakness and sleepiness)

All of these symptoms lead to a person that is low on energy and can have serve discomfort due to an extremely high fever and a very sore throat that can lead to discomfort when eating or drinking. Use of lozenges and lots of bed rest are the first steps to being comfortable as the virus runs its’ course. The final issue would be that the spleen can sometimes be enlarged accompanied by severe pain in the upper left part of the belly. Contact sports and lifting heavy items should be avoided at all costs. If symptoms arise, consider a mono test kit to be approved by your physician to check for Mono. This consists of a blood test that will rule out all other possible issues so that a proper diagnosis can be assigned to the symptoms. The virus can last 4-6 weeks, yet all contact sports should be avoided for 2-3 months before reentry to avoid lasting problems such as a ruptured spleen.

Detecting Rheumatoid Arthritis

Do you suspect your patient has rheumatoid arthritis? If so, then you need a reliable rheumatoid factor test that can give you definitive answers.

Rheumatoid Test
When you’re searching for a rheumatoid factor test for your medical office, laboratory, or hospital, you can count on Diagnostic Automation / Cortez Diagnostics, Inc. We make high-quality serological testing supplies that are made for the qualitative and semi-quantitative measurements of RF in human serum. These serology tests are based on the principle of latex agglutination assay by Singer and Plotz.

What Is Rheumatoid Factor?
Rheumatoid factor is an antibody that is measurable in the blood. It is actually an antibody that can bind to other antibodies. Antibodies are normal proteins in our blood that are important parts of our immune system. However, Rheumatoid factor is not usually present in an unaffected individual.

About Rheumatoid Factor
Rheumatoid factor is detectable in the blood of approximately 80% of adults with rheumatoid arthritis. Sometimes rheumatoid factor can be detected in the blood of normal individuals and of those with other autoimmune diseases that are not rheumatoid arthritis. In people with rheumatoid arthritis, high levels of rheumatoid factor can indicate a tendency toward more aggressive disease and/or a tendency to develop rheumatoid nodules and/or rheumatoid lung disease.

What’s Mono?

K-I-S-S-I-N-G. Ever heard of the kissing disease? If you guessed mono, you’re right. However, you don’t only get mono from kissing, despite what you may have heard on the middle school playground. Infectious mononucleosis, mono for short, is caused by the Epstein-Barr virus (EBV), which is a type of herpes virus. Other viruses in the herpes family cause cold sores and chicken pox.

How do you get it?
Mono is contagious, which means you can spread the virus to other people who haven’t had mono before. Even though you can get mono from kissing someone infected with EBV, there are other ways you can get it, but they all involve contact with saliva. Sharing straws, toothbrushes, or food from the same plate can also spread mono.

At first, people usually don’t feel sick after getting infected with the EBV virus. So someone could be infected — and be spreading mono — and not even know it. That’s why it’s important not to share things like forks, straws, water bottles, or lip gloss

Who is most susceptible?
Most people who get mono are between the ages of 15 and 25, but younger kids can get it, too. The mono virus affects the lymph nodes, throat, salivary glands, liver, spleen, and blood, and it can make a person feel tired and achy all over. It can also make you lose your appetite. Our mononucleosis test is quick, easy and accurate. Learn more about our Serology tests from Diagnostic Automations / Cortez Diagnostics today.

Serology Tests


Serology tests are conducted for the scientific study of blood serum and other bodily fluids.  Serology tests are performed for several purposes.  One use of a Serology test is for diagnostic purposes when an infection is suspected.  A Serology test can identify certain antibodies in serum that are formed in response to an infection against foreign proteins (for example from blood transfusion), or to one’s own proteins (for instance, autoimmune disease).  A serology test can also determine if there has ever been exposure to a particular microorganism in the past, not necessarily indicating a current infection.


A serology test additionally can be employed to detect current active infection, or past infection, in people who are at risk for reactivation of infection (such people with suppressed immune systems, organ transplants, HIV, Syphilis, etc.).  In addition, Serology tests are often used by epidemiologists to determine the prevalence of a disease in a certain segment of population.  These serology tests are sometimes performed by random, anonymous sampling.  Serology tests are also important tools that may be used forensically, specifically to reveal a piece of evidence for a crime report, or court case.


Los Angeles-based Diagnostic Automation/Cortez Diagnostics, Inc. is pleased to offer a wide range of serology tests for the quick and reliable measurement of specific antibodies in human serum samples.  Some of these serology tests are latex agglutination tests (latex fixation) which use latex particles as passive carriers where particles clump together following the addition of the antibody on the serology test.

•     One such serology test is the Latex ASO Serology Test which is a serology test intended for the qualitative and semi-quantitative measurement of antibodies to streptococcal exoenzymes in human serum.  Packaged in convenient boxes of 50 serology tests, this (antistreptolysin O) ASO serology test is easy to use and cost effective for hospitals, doctors’ offices, and laboratories worldwide who need quick and easy test results for individual patients, or testing for a large segment of the population.

•        Another popular serology test is the CRP Serology Test that is used for the qualitative and semi-quantitative measurement of C-reactive protein in human serum.  This simple and easy-to-use CRP Serology Test is based on the principle of the latex agglutination assay described above and detects protein markers for inflammation in the body.   The major advantage of this serology test is the rapid three (3) minute reaction time.  Packaged in boxes each of 100 serology tests, this top quality serology test is convenient for any testing site diagnosing patients with acute and chronic inflammatory conditions.

•        A third latex serology test is the Mono Serology Test which is intended to be used for the qualitative and semi-quantitative determination of human heterophile antibodies associated with Infectious Mononucleosis (IM).  Ordering these serology tests is easy and convenient.  The Mono Serology Tests are distributed in boxes of 50 serology tests and are to be applied in-vitro diagnostic use only.  These Mono Serology Tests are known for their high sensitivity and specificity.

•        The fourth latex serology test is entitled the RF Serology Test which is intended for the qualitative and semi-quantitative measurement of RF (rheumatoid factor) in human serum.  The frequent occurrence of rheumatoid factors in rheumatoid arthritis makes them useful for diagnoses, like those employed by this serology test, and subsequent monitoring of the disease.   The major advantage of this RF Serology Test is rapid performance (3 minute reaction time) and lack of heterophile antibody interference.  Interested parties can obtain these useful and reliable serology test kits each containing 100 boxes.

•        The fifth latex serology test is the SLE Serology Test which is used as an aid in the diagnosis of Systemic Lupus Erythematosus (SLE) through the detection and quantitation of serum anti nucleoprotein factors associated with SLE.  The principle of the SLE Serology Test is based on the agglutination reaction between latex particles coated with DNP being brought into contact with a serum, which contains antinuclear antibodies.  A visible agglutination on the serology test indicates a positive reaction.  The reaction time for this occurrence on this serology test is one minute.  These top quality serology test kits are packaged in 50 boxes each kit.

The last superior quality serology test manufactured and distributed by Diagnostic Automation/Cortez Diagnostics, Inc. is the convenient and highly effective RPR Serology Test which is a Rapid Plasma Reagin –RPR Serology Test that is a non-treponemal flockulation test used for qualitative and semi-quantitative determination of reagin antibodies in serum or plasma from persons with syphilis.  The antigen used in the serology test kit is a modification of VDRL antigen, which contains micro-particulate charcoal to enhance the visual difference between a positive and negative result.  If a specimen on this serology test contains reagin, flocculation occurs with a coaglutination of carbon particles contained in the antigen suspension, which appears as black clumps.  Non-reactive specimens on the serology test appear as an even light gray homogenous suspension.  These safe and cost-effective serology test kits are distributed in packages of 100 or 500 boxes, and are for in-vitro diagnostic use only.  Reactive RPR Serology test specimens should be subjected to further confirmation testing.
