There are ISO approved companies who will certificate your scales Like this one http://www.ukas.org/calibration/schedules/Actual/8296Calibration%20Multiple.pdf BW John From: Clinical biochemistry discussion list [mailto:[log in to unmask]] On Behalf Of Catrin Searell (BCUHB - Pathology) Sent: 19 December 2016 10:35 To: [log in to unmask] Subject: 24h urines Dear all Would anyone mind sharing with us their ISO-proof method of measuring 24h urine volumes? Is it good enough to weigh the collection and subtract the weight of an identical (empty) container? Or do we have to pre-weigh each container and write the weight on the bottle before giving them out? Any other advice would also be much appreciated e.g. how "good" your scales have to be etc. Many thanks Catrin Catrin Searell Gwyddonydd Clinigol/Clinical Scientist Adran Gwyddorau Gwaed/Department of Blood Sciences Bwrdd Iechyd Prifysgol Betsi Cadwaladr University Health Board Ysbyty Gwynedd Bangor LL57 2PW ________________________________ Cymraeg Rhybudd Ebost (2010) - Bwrdd Iechyd Prifysgol Betsi Cadwaladr Fe'ch cynghorir i ddarllen rhybydd ebost Bwrdd Iechyd Prifysgol Betsi Cadwaladr (a'i argraffu er mwyn cyfeirio ato yn y dyfodol).
