Differentiation between viral or bacterial respiratory infection

Respiratory tract infections occur throughout the year. These infections are viral or bacterial in nature. In order to reach the most appropriate treatment, it is very important that the differentiation of the nature of the infection is carried out at the stage of manifestation of symptoms.

This can be challenging since uncertainty in diagnosis often leads to misuse of antibiotics or unsafe medications, mainly for the pediatric age group.

An unsafe treatment can only be avoided through the correct diagnosis which is already ensured by the newest test offered by Intermedica. This test performs the differentiation between viral and bacterial infection in the respiratory tract.

The test combines two important markers: MxA protein (Myxovirus resistance protein) and C-reactive protein (CRP). MxA and CRP, as two complementary tests, distinguish whether we are dealing with a viral or bacterial respiratory infection, saving time and avoiding wrong treatment.

The MxA protein provides information on acute viral infections of the respiratory tract. Levels of this protein in the blood increase significantly when viral infection occurs. The concentration of MxA is significantly different in adults and asymptomatic children, increases during viral infection to different levels, and decreases to initial values ??serving as an indication of elimination of infection. Such differentiation allows not only the use of MxA as a specific marker in viral infections, but also differentiates between the effect of viral and bacterial infection on the organism.

C-Reactive Protein (CRP) is the predominant acute phase protein in respiratory infections, used in routine diagnostics. In healthy individuals the levels of this protein are low. Bacterial infection, inflammation and tissue damage cause CRP levels to rise. The increase occurs significantly within 6-12 hours from the onset of inflammation. This sensitivity makes this protein an important indicator of the effect of antibiotic treatment.

The sensitivity of CRP and MxA protein during viral or bacterial infections makes it necessary to perform a test that measures both proteins simultaneously. During viral infection, the increase of CRP accompanies the increase of MxA levels, the opposite occurs during bacterial infection, where the level of MxA remains at normal values. In this way, it is determined whether the individual is affected by a viral or bacterial infection.

Testing for the two proteins in both adults and children is done through a simple blood sample. Because a small amount is needed for analysis, venous blood is not necessary. This means that the test can also be performed from peripheral blood through a finger prick, thus constituting a much simpler and effective method in children or individuals who encounter difficulties during this procedure.

The results after laboratory analysis are ready in a short time. This ensures the fastest and most efficient solution in starting the most appropriate treatment for the patient.
