Ethylene Glycol and Methanol are now available as part of our ED Toxicology scheme; these analytes have been added In response to the ‘NHS Services, Seven Day Working’ from NHS England. The Association for Clinical Biochemistry and Laboratory Medicine published guidance on the clinical biochemistry tests that may be required to allow for the optimal clinical management of ‘Critical’ and ‘Urgent’ patients. They recommended that Ethanol, Methanol and Ethylene Glycol be included as ‘Urgent’ tests and should be available within 4 hours. They did however acknowledge that for some tests such as Ethylene Glycol which may require onward transfer to a specialist referral laboratory for analysis, the availability of results within the suggested time frames may not be achievable at present by all laboratories.
