Thai hospital labs after the ISO 15189:2022 deadline: two accreditation tracks, one equipment paper trail

ISO 15189:2022, the fourth edition of the medical-laboratory standard, was published on 6 December 2022, and ILAC resolved on a three-year transition. On 6 December 2025 accreditation to the 2012 edition stopped being recognised under the ILAC Arrangement. That question is settled; any lab holding ISO 15189 today has already been assessed against the 2022 edition. The question still open sits with procurement: what did the new edition and Thailand's accreditation system change about buying instruments for a hospital lab?

What the 2022 edition does, confirmed from ISO's own publication record: it cancels and replaces both 15189:2012 and ISO 22870:2016, the previously separate point-of-care testing standard. The structure is realigned to ISO/IEC 17025:2017, the wording is less prescriptive, and clinical risk to the patient carries more weight. Absorbing POCT has a real consequence in a hospital: in principle, bedside analysers that wards procure on their own now sit inside the same standard's scope as the central lab, no longer out of sight.

Thailand's two accreditation tracks

The first is the Medical Technology Council's LA programme, run against the Medical Technology Standards, B.E. 2565 edition. Certificates run three years and then enter Re-LA rounds. The council's programme page reports a cumulative total of over 700 accredited facilities as of B.E. 2569 (2026): government and private hospitals, medical-technology clinics and testing companies. By volume, this is the main road for hospital labs nationwide.

The second is ISO 15189 through the Bureau of Laboratory Quality Standards (BLQS) at the Department of Medical Sciences, the country's sole ISO 15189 accreditation body. The programme has run since 2004; the department's journal reported 201 laboratories accredited cumulatively by 2019, and its e-Accreditation process cut the procedure from 220 days to an average of 77. BLQS also accredits ISO 15190, the medical-laboratory safety standard, alongside.

Our position, plainly: a typical hospital lab starts with LA, because the criteria, the assessors and the document cycle were designed for the Thai context. ISO 15189 pays off when the lab takes referral work, reports across borders, or serves pharmaceutical and research clients whose contracts name the international standard. The tracks do not exclude each other, and plenty of large labs hold both.

The paperwork that must arrive with the instrument

The clause text of ISO 15189:2022 is copyrighted and we do not reproduce it here; mapping requirements clause by clause is your quality manager's job with the real text. What we can vouch for from the supplier's side, having delivered equipment into both LA and ISO assessments many times over, is that what assessors ask to see follows a repeating pattern:

• Quotation, delivery note and tax invoice whose specifications match exactly, for the asset register
• Traceable calibration certificates for balances, pipettes, thermometers and every measuring device that touches a result
• Acceptance-test records showing the instrument was verified before it met a real specimen
• Manuals in a language the staff actually read, with user-training records
• In-country parts and service access, with response times in writing

Every item on that list is hard to obtain retroactively. Goods receipt is the one moment you get all of it without chasing the vendor, so writing it into the TOR or purchase order costs less than closing a corrective action later. Always.

The safety twin: ISO 15190

BLQS assesses ISO 15190 together with 15189, so the Class II biosafety cabinet, the emergency eyewash, spill kits and sharps containers turn up in the same assessment round as the analysers. Budget the two together from the start rather than letting safety equipment wait for a nonconformity to force it.

Facts checked against ISO's and ILAC's publications, the Bulletin of the Department of Medical Sciences, and the Medical Technology Council's programme page on 24 August 2026. The cumulative counts (201 labs by 2019, over 700 facilities by 2026) are as-of figures from those sources, not today's totals. Verify with the accreditation bodies directly before citing this in procurement documents.
