Features of Sofia 2: 

Quidel Sofia 2 has several features in store that account for its remarkable performance. Some crucial features are as follows: 

1. Automated Results: 

This Immunoassay analyzer specializes in generating automated results. These are displayed on the screen, sent to Virena, or can be taken as a printout. The emphasis here is the elimination of operator-operator variability that is usually associated with the interpretation of visually-read test results. 

2. Data Management: 

This analyzer machine is efficient in managing the test results and all the relevant data. The users can choose any of the following ways to store and manage this information. 

  • Virena wireless connectivity 
  • USB storage mechanism that provides PC storing and analysis 
  • QC, test, and calibration results stored on-board 
  • External printing through a printer for hard copies of the stored data 

All the choices remain the same for every test, be it small or a lengthy one. 

3. User Interface and Security: 

This is probably the best thing about this analyzer machine. It uses intuitive software that is convenient, fast, and performs rapid operations to navigate between stored information or run a particular patient’s samples. Moreover, it provides options to the users to set access rights and prevent unauthorized use of the machine. This way, you have instantaneous data which is in safe hands. 

Sofia 2 Advantages: 

Sofia 2 Immunoassay analyzer provides a mammoth of advantages to the supervisors and the patients simultaneously. 

  • It uses advanced fluorescent technology for optimum performance. 
  • It comes with two development modes to provide flexibility and specific demands based on the workflow. 
  • Its Walk Away automation feature eliminates the need for the supervisors and operators to wait for the test results. 
  • Its barcode technology reduces errors and runtime recorded during manual patient recordings. 
  • It comes with a replaceable and long-lasting battery. A single charge of this analyzer can cover a significant time. 
  • Its Walk Away mode is convenient for analyzing a patient’s sample, and the Read Now mode eases the reading of multiple patients’ samples. 
  • This analyzer specializes in using proprietary algorithms for data analysis and signal interpretation. This helps determine the necessary results automatically and saves so much time. 
  • The supervisors can either display the test information on the screen or let the Sofia 2 store it within its memory. 
  • This machine also provides hard copies of the data. It provides external connectivity through which the users can connect to a printer and generate the hardcopies when needed. 

How to use Quidel Sofia 2

Delayed reading mode (Walk-Away)

The sample is incubated on the analyzer, and the result is read automatically.

Immediate reading mode

The sample is incubated on the counter using an external timer and subsequently introduced into the equipment to read the result. This method works for high sample volumes.

Available Parameters
