1. Introduction The purpose of this document is to provide interim recommendations to laboratories and stakeholders involved in laboratory testing for Middle East respiratory syndrome coronavirus (MERSCoV). The recommendations have been prepared by WHO based on current knowledge. They have been reviewed by laboratory experts, including those with experience handling this virus and other coronaviruses, and also those with expertise in the development of diagnostic assays for coronaviruses. WHO is closely monitoring developments related to this virus and will revise these recommendations when necessary. Unless revisions are made, this document will expire on 28 February 2014.（中东综合征快速检测试剂盒）

2. Indications for testing WHO recommends that clinicians,which will be updated as needed, to determine which patients should be tested. Testing for other respiratory pathogens using routinely available laboratory procedures as recommended in local management guidelines for community-acquired pneumonia should also be performed but should not delay testing for MERS-CoV. Examples of other aetiologies include Streptococcus pneumoniae, Haemophilus influenzae type b, Legionella pneumophila, influenza viruses, and respiratory syncytial virus.

3. Specimen collection and shipment Whenever specimens are collected from cases under investigation, infection control guidelines should be followed.There is now increasing evidence that lower respiratory tract specimens such as bronchoalveolar lavage, sputum and tracheal aspirates contain the highest viral loads (1, 2) and these should be 2 collected when possible. A recent report of a case series of MERS-CoV infections detected in Saudi Arabia (3) has also demonstrated the importance of upper respiratory tract specimens such as nasopharyngeal/oropharyngeal swabs for detecting the virus. It is recommended that both upper and lower respiratory tract specimens be collected whenever possible. To increase the likelihood of detecting the virus, multiple samples from multiple sites should be collected over the course of the illness. Even after the initial detection of the virus, continued sampling and testing will add to current knowledge about the duration of virus shedding and is strongly encouraged. Virus has been detected in urine and faeces but at levels below those found in the lower respiratory tract(1). To date, there is little information on the value of whole blood as a specimen for MERS-CoV detection. Serum samples should be collected. Paired samples are preferred but single samples are also of value. Paired serum samples should be collected 14-21 days apart, with the first being taken during the first week of illness. If only a single sample is to be collected, it should be done at least 14 days after onset of symptoms. Table 1 lists the specimens that can be collected as well as their storage and transport requirements. Specimens should reach the laboratory as soon as possible after collection. The importance of proper handling during transportation cannot be overemphasized. When there is likely to be a delay in the laboratory receiving respiratory tract specimens, it is strongly recommended that the specimens be frozen, preferably to -80°C, and shipped on dry ice. It is, however, important to avoid repeated freezing and thawing of specimens. Serum should be separated from whole blood and can be stored and shipped at 4°C or frozen to -20°C or lower and shipped on dry ice. The storage of respiratory and serum specimens in domestic frost-free freezers should be avoided, owing to their wide temperature fluctuations. Transport of specimens within national borders should comply with applicable national regulations. International transport of MERS-CoV specimens should follow applicable international regulations as described in the WHO Guidance on Regulations for the Transport of Infectious Substances 2013-2014 available
