SPINA Thyr has been released in version 3.4. This new version is a major upgrade that implements a plethora of new functions. The most important new feature is the option to calculate Jostel's TSH index and TTSI, two simple estimates of central homeostatic function that have been requested my many users. Additionally, SPINA Thyr is now able to export results of calculations as text files or HL7 messages. Moreover, handling of reference ranges has been improved and multiple bugs were fixed.
SPINA Thyr 3.4 is available for free from http://spina.sf.net for Linux, Mac OS X and Windows.
