With immediate effect SPINA Thyr is available in version 4.0. This is a major upgrade that implements a plethora of new functions.

SPINA Thyr is now able to calculate z-transformed standardised variants of SPINA-GD and Jostel's TSH index, two Gaussian distributed structure parameters for peripheral deiodination and pituitary function. Additionally, the export of findings as HL7 messages, which is now the standard export format, has been improved, and SPINA Thyr is now able to read findings in HL7's ORU^R01 format. Together with the new import and export functions an editor for basic patient data has been introduced.

Additional new updates include improved printing support, bug fixes and a partial rewrite of the code to support NASA’s 10 rules for developing safety-critical code. This feature is expected to improve reliability and dependability of SPINA.
