VIDAS® B·R·A·H·M·S PCT™

PCT-Guided Antibiotic Therapy

Procalcitonin (PCT) is a biomarker that can help:

  • Assess initial risk of sepsis
  • Monitor patient progress and mortality risk during treatment for sepsis
  • Determine whether to start antibiotics for
    Lower Respiratory Tract Infection (LRTI)
  • Determine when to discontinue antibiotics

Results within 20 minutes.

  


Overview

VIDAS B·R·A·H·M·S PCT is an automated test for use on the instruments of the VIDAS family of instruments for the determination of procalcitonin in human serum or plasma (lithium heparinate) using the ELFA (Enzyme-Linked Fluorescent Assay) technique.

Used in conjunction with other laboratory findings and clinical assessments, VIDAS B•R•A•H•M•S PCT is intended for use as follows:

  • to aid in the risk assessment of critically ill patients on their first day of ICU admission for progression to severe sepsis and septic shock
  • to aid in assessing the cumulative 28-day risk of all-cause mortality for patients diagnosed with severe sepsis or septic shock in the ICU or when obtained in the emergency department or other medical wards prior to ICU admission, using a change in PCT level over time
  • to aid in decision making on antibiotic therapy for patients with suspected or confirmed lower respiratory tract infections (LRTI) - defined as community-acquired pneumonia (CAP), acute bronchitis, and acute exacerbation of chronic obstructive pulmonary disease (AECOPD) - in an inpatient setting or an emergency department
  • to aid in decision making on antibiotic discontinuation for patients with suspected or confirmed sepsis

VIDAS B·R·A·H·M·S PCT is not indicated to be used as a stand-alone diagnostic assay. PCT results should always be interpreted in the context of the clinical status of the patient and other laboratory results. PCT levels for the prediction of mortality and overall mortality are strongly dependent on many factors, including pre-existing patient risk factors and clinical course.

VIDAS B·R·A·H·M·S PCT is available to order now via our eCommerce store.

Specs

Storage Conditions

  • Store the VIDAS B·R·A·H·M·S PCT (PCT) kit at 2-8°C.
  • Do not freeze reagents, with the exception of calibrators and controls after reconstitution.
  • Store all unused reagents at 2-8°C.
  • After opening the kit, check that the SPR® pouch is correctly sealed and undamaged. If not, do not use the SPRs.
  • Carefully reseal the pouch with the desiccant inside after use to maintain stability of the SPRs and return the complete kit to 2-8°C.
  • If stored according to the recommended conditions, all components are stable until the expiration date indicated on the label. Refer to the kit composition table for special storage conditions.

Uses

PCT-Guided Antibiotic Therapy for Sepsis

For more information, please see full package insert for VIDAS B•R•A•H•M•S PCT (30450-01).

VIDAS B•R•A•H•M•S PCT can help clinicians make better-informed decisions and help improve accuracy of early sepsis diagnosis, using procalcitonin to provide critical biomarker information.

PCT-Guided Antibiotic Therapy for Lower Respiratory Tract Infection

50% of antibiotics prescribed for acute respiratory conditions are unnecessary.1  LRTI can present in many different ways: acute bronchitis, community acquired pneumonia, and acute exacerbation of COPD.  Clinical characteristics are non-specific: cough, sputum, fever, and shortness of breath.  In the past, this ambiguity was met with almost-automatic antibiotic therapy.  Today we have better information and better ways to decide if antibiotics are warranted.

Procalcitonin (PCT) provides critical biomarker information.  PCT is produced by numerous organs at a cellular level after bacterial pro-inflammatory stimulation.2,3

  • PCT rises in 3 - 6 hours
  • Half-life of 20 - 24 hours
  • Early identification & risk assessment

About PCT

What if you had an extra piece of information to help assess sepsis patients?

PROCALCITONIN: the “extra piece” that can make the difference

Procalcitonin (PCT) is often increased during systemic bacterial infection and sepsis. This biomarker is recognized as a useful tool in the diagnostic process.

VIDAS B·R·A·H·M·S PCT is an innovative procalcitonin assay. This assay is performed on the VIDAS® system, which is fully adapted for emergency or stat conditions where rapid turnaround time is important.  

What is PCT?

PCT is the prohormone of calcitonin (CT). Whereas CT is secreted by the C-cells of the thyroid after hormonal stimulation, PCT can be produced by numerous cell types and organs after proinflammatory stimulation, especially when caused by bacterial challenge.1

In healthy people, plasma PCT concentrations are found to be below 0.05 ng/ml, but can increase up to 1,000 ng/ml in patients with severe sepsis or septic shock.

Elevated PCT levels indicate bacterial infection accompanies by a systemic inflammatory reaction.

Localized infections do not generally cause circulating PCT increases. Slightly elevated PCT concentrations are observed in bacterial infections with minor systemic inflammatory response.

Very high values have been observed during acute disease conditions with severe systemic reactions to infection, in cases of severe sepsis or septic shock.
