C4G BLIS is a free open-source laboratory information system (LIS) designed to "track patient specimens and laboratory results"[1] and is primarily utilized in Africa.

Product history

The U.S. Centers for Disease Control and Prevention (CDC) initiated a collaboration with the Computing For Good (C4G) group at the Georgia Institute of Technology (Georgia Tech) in April 2009[2], with the goal of creating a LIS designed specifically for service-delivery level laboratories with limited resources.[3][4][5] The software — dubbed Basic Laboratory Information System or BLIS — was developed primarily by students at Georgia Tech with the feedback of the CDC and laboratory personnel in various parts of Africa[3], culminating in the first implementation of the software at Cameroon's Buea Regional Hospital laboratory in April 2010.[4][6] Additional pilot implementations of the software were then planned for in Uganda, Tanzania, Ghana, and Cameroon in cooperation with those countries' respective Ministries of Health.[3][2]

Development continued on BLIS after the initial deployments, though it's not clear when exactly it was released to the public in an open-source format. Public change log entries begin with version 1.09 in July 2011[7], with initial open-source commits appearing on GitHub in September 2012.[8]


Features include[2][7]:

  • patient and specimen registration
  • results entry
  • queries
  • reporting
  • lab configuration tools
  • test catalog
  • multilingual
  • custom fields
  • commenting
  • billing
  • barcode support
  • inventory management

Hardware/software requirements
