For a stay exceeding 15 days in Kurdistan even nationals of some visa free countries need residency permission. The short-term requirements are mentioned by the Kurdistan Regional Government and include:
Evidence that the applicant has undertaken a blood test according to the procedures of the residence office. A form to obtain a blood test appointment can be collected from the residence office as part of the application process. The blood test result can usually be obtained within 2-3 days.
Given eg that Wikitravel has “… a compulsory blood test to check for Hep C and HIV (although this does not seem to be the case anymore).” which site best reflects or what is the current situation regarding the blood test requirements?
Evidence of the current ‘de facto’ situation conflicts with stated official guidance. I seek an answer that disambiguates the situation rather than merely repeats one or other of the conflicting versions. I have quoted what I believe is the Government’s official (public) stance and also Wikitravel which indicates what is published is not what actually happens. In this case I am much more interested in current practice than in theory. One instance (a friend who late in 2014 did not need a blood test for a visit of one month) is sufficient further to call in to question the reliability of the stated official stance but not enough to establish with any degree of certainty whether I would need a test or not. (My friend is of the same, British, nationality though happens to have been born in Kurdistan).
For that I would appreciate either more up-to-date (ie probably different) official information (obviously with the source disclosed) or details (with provenance) of current practice. A single example (as I have already) does not illustrate the general rule I seek.
However there is no urgency at present. The trip I was expecting seems to have been either called off or deferred. Given the situation with ISIL I am not surprised though the nearest I have heard by way of a reason is, strangely, “Because of the situation in Yemen”.
 According to gov.uk, now 30 days:
Entry requirements section - immigration officials at airports in the Kurdistan Region of Iraq routinely allow travellers to get a visa on arrival; these visas are only valid for 30 days
