The Advia Centaur XP is a high-performance immunoassay analyzer developed by Siemens Healthineers. It’s designed for medium to high-volume laboratories that need fast, accurate, and automated testing across a wide range of diagnostic needs. From hormone testing to infectious disease panels, the Centaur XP delivers high throughput and precise results—supporting excellence in patient care.

In this article, we’ll explore what makes the Advia Centaur XP a trusted choice for clinical labs and how it helps improve efficiency, accuracy, and testing speed.

What Is the Advia Centaur XP?

The Advia Centaur XP is a fully automated immunoassay analyzer that performs a variety of blood-based tests. It measures levels of hormones, proteins, infectious disease markers, and more using chemiluminescent immunoassay technology. This allows labs to detect and monitor conditions such as thyroid disorders, fertility issues, cardiac events, and infectious diseases with high sensitivity and specificity.

Built for busy labs, the analyzer processes many tests in less time—without sacrificing precision.

Key Features of the Advia Centaur XP

1. High Test Throughput

The analyzer can perform up to 240 tests per hour, making it a great fit for mid- to large-sized labs. It supports continuous operation, with the ability to load samples and reagents without interrupting ongoing tests.

2. Broad Test Menu

The Centaur XP offers over 70 assays covering:

• Thyroid function tests (TSH, Free T3, Free T4)
  
  

• Fertility and reproductive hormones (FSH, LH, Progesterone, Estradiol)
  
  

• Cardiac markers (Troponin I, BNP, CK-MB)
  
  

• Tumor markers (CEA, CA-125, AFP, PSA)
  
  

• Infectious diseases (HIV, Hepatitis B & C, Syphilis)
  
  

• Vitamin levels (Vitamin D, B12)
  
  

• Therapeutic drug monitoring and autoimmune testing
  
  

This wide menu lets labs perform both routine and specialty testing from a single platform.

3. Random Access and Continuous Loading

The system supports random access testing, allowing high-priority or STAT samples to be processed immediately. It also offers continuous loading of samples, reagents, and consumables, so testing can continue without delays.

• Improve sensitivity in detecting low-level analytes
  
  

• Reduce background noise
  
  

• Deliver consistent and reproducible results
  
  

6. User-Friendly Interface

The analyzer includes a modern touchscreen interface that helps lab technicians:

• Set up test runs
  
  

• Monitor assay progress
  
  

• Track reagent levels
  
  

• Access quality control data
  
  

• Review test results quickly
