Markers of infectious diseases

Chronic infection with cytomegalovirus or a history of contact with the causative agent. CMV IgG can be detected 7-14 days after infection.

Cytomegalovirus infection is detected during the acute period. CMV IgMs appear in the blood as early as 3-4 days after the start of infection and persist for several months (after which they degrade).

Infectious mononucleosis is an acute viral infection characterised by fever, sore throat and enlarged lymph nodes. The source of infection is people with acute or chronic infectious mononucleosis, as well as healthy carriers.

The test indicates a history of contact, active infection or viral relapse.

The study shows an acute infection of infectious mononucleosis caused by Epstein-Barr virus. The increase in IgM antibodies to EBV capsid antigen (Epstein barr) disappears within 4-6 weeks.

The IgG antibody test for tick-borne encephalitis is administered 3-4 weeks after the injection to determine the course of the chronic disease or to assess a pre-existing infection.

Tick-borne encephalitis is a dangerous infectious disease spread by ticks. Unpasteurised milk can also cause infection.

It allows you to identify whether a person is infected with H. pylori, as well as those with signs and symptoms of gastrointestinal disease and asymptomatic individuals.

Helicobacter pylori IgG antibodies – a serological blood test that shows specific IgG antibodies against Helicobacter pylori. Helicobacter pylori causes diseases of the stomach and duodenum, such as erosion, ulcers and chronic gastritis. Positive IgG results indicate that the person has been infected or is currently infected with an active form of Helicobacter pylori infection. Helicobacter pylori IgG antibody testing is required if you have problems with indigestion, fullness/heaviness after eating, bloating or heartburn.

Helicobacter pylori is a microorganism found in the stomach. This bacterium is special because, unlike many others, it is adapted to living in acidic environments. According to the WHO, the majority of the human population (30-40%) carries this bacterium in their stomach lining.

It has been observed that people without this bacterium are less likely to suffer from gastrointestinal diseases such as erosions, ulcers and chronic active gastritis. Sufferers have a “burning” stomach after eating, irritation and straining. In this context, people with ulcers are often advised to eradicate the Helicobacter pylori bacteria in the body so that they no longer irritate it. Depending on their activity and quantity, these bacteria interfere with sleep quality, cause bad breath and promote the formation of cancer cells.

In addition to Helicobacter pylori bacteria, gastric diseases are also influenced by factors such as genotype, stress, smoking, coffee, alcohol, use of anti-inflammatory drugs (orally) and poor dietary habits. Often people with stomach problems like to eat before going to bed, which they should not do. Overeating or prolonged fasting and skipping breakfast are also common. Your diet should be regular throughout the day. If you have stomach problems, you should avoid dairy products, citrus fruits, chocolate, fizzy drinks, and start a cycle of stomach calming drugs or, alternatively, take therapeutic licorice teas.

There are several ways to detect the bacterium:

– Serological blood tests
– Detection of antigens in a faecal sample
– Gastric mucosal biopsy
– Breath sample

Inflammation and damage to the stomach lining caused by the bacteria are manifested by abdominal pain, indigestion, bloating, and a feeling of heaviness after eating.

A serological blood test detects specific IgG antibodies against Helicobacter pylori. A positive test result indicates that the person has had an infection or is infected with an active form of Helicobacter pylori infection. IgA and IgM antibody tests are recommended to increase the reliability and specificity of the test.

The later stages of Lyme disease and chronic disease are indicated by IgG antibodies, which start circulating in the blood 4-6 weeks after the infected tick bites. Elevated levels of these antibodies can persist for more than a year after contracting Lyme disease.

Lyme disease (borreliosis) is a dangerous infectious disease spread by ticks.

To detect chronic infection caused by Mycoplasma pneumoniae or previous contact with the causative agent. Mycoplasma pneumoniae IgG titre rises later, after 3-4 weeks.

For the diagnosis of acute infection caused by Mycoplasma pneumoniae. Mycoplasma pneumoniae serum primary M-class antibody (IgM) titres rise after approximately 2 weeks. from the time of infection or even later, and disappears within about a year.

This test shows whether the patient has sufficient immunity to tick-borne encephalitis and when re-vaccination is needed.
