Procalcitonin Antibody; Used To Diagnose the Level of Procalcitonin (PCT) In the Body
Procalcitonin antibody test is used to diagnose the level of
procalcitonin in the body, with the help of wet lab analysis. Procalcitonin is
a naturally occurring peptide composed of amino acids which are known as the
proline, glycine, arginine, and valine. This particular peptide is found in the
human blood and helps in the production of polysaccharides which are part of
the immune system. Procalcitonin is produced in response to an antigen, which
is known as the calcitonin gene-related antigen. The procalcitonin antibody has
recently emerged as one of the most effective treatments for patients with
chronic obstructive pulmonary disease.
There are two types of the procalcitonin antibody, such as
polyclonal procalcitonin antibody and monoclonal procalcitonin antibody.
Studies have shown that the polyclonal antibodies help reduce lung inflammatory
response to activated interferon and amyloid protein. Procalcitonin exhibits
greater specificity than other proinflammatory markers in identifying patients
with sepsis and can be used in the diagnosis of bacterial infections. Microbial
infected individuals and procalcitonin variance in healthy individuals has
increased the use of the procalcitonin
antibody to improve bacterial infection identification and develop
antibiotic therapy.
Thus, with the increasing prevalence of chronic diseases
such as HIV, tuberculosis, sepsis, and hepatitis, the demand for procalcitonin
antibody is also increasing. According to the Centers for Disease Control and
Prevention (CDC), in 2019, the majority (51%) of TB cases continued to be
reported from 4 states: Florida (6.3%), New York (8.5%), Texas (13.0%), and California
(23.7%). While, in 2018, around 542 deaths in the United States were attributed
to TB. This is an increase from 515 deaths attributed to TB in 2017. Thus, with
the increasing prevalence of aforementioned chronic diseases, the demand for
procalcitonin antibody is also increasing.
Procalcitonin antibody test is used to determine the risk
that a critically ill person will progress to severe sepsis and septic shock,
or the risk of the person dying. Moreover, the test is used to distinguish
between bacterial and non-bacterial causes of infections, such as pneumonia and
meningitis. The higher the procalcitonin level, the more severe the infection.
