INTENDED USE
Procalcitonin (PCT) Test card (Colloidal Gold)is a rapid and convenient immunochromatographic assay for the semi-quantitative detection of human Procalcitonin in serum or plasma . It is intended for professional use as an aid in the diagnosis the treatment of severe bacterial infection and sepsis.
SUMMARY
PCT levels are elevated in bacterial sepsis, especially severe sepsis and septic shock. PCT can be used as a prognostic indicator of sepsis, and it is also a reliable indicator of acute severe pancreatitis and its main complications. For patients with community-acquired respiratory infections and air-conditioning-induced pneumonia, PCT can be used as an indicator of antibiotic selection and efficacy judgment.
This test is an immunological diagnostic test used for detection of PCT antigen based on the colloidal gold-immunochromatography assay. This method is rapid and convenient to use and requires few equipment.It can be performed within 15-20 minutes by minimally skilled personnel.
PRINCIPLE OF THE TEST
Procalcitonin (PCT) Test card(Colloidal Gold) is an antigen-capture immunochromatographic assay, detecting PCT in blood samples. Monoclonal antibodies specifically against PCT are conjugated with colloidal gold and deposited on the conjugate pad . When an adequate volume of the test sample is added and the PCT, if any in the sample, will interact with the colloidal gold conjugated antibodies. The antigen-antibody-colloidal gold complex then will migrate towards the test window until the Test Zone (T) where they will be captured by immobilized antibodies, forming a visible red line (Test line) indicating a positive result. If PCT is absent or below Minimum detection limit(0.2ng/ml) in the sample, no red line will appear in the Test Zone (T), indicating a negative result.Absence of a red control line in the Control Zone is an indication of an invalid result.
