NABL (National Accreditation Board for Laboratories) NABL is a private， non-profit company founded in 1975 that is based in India. It offers accreditation programs for testing laboratories throughout the country.
The NABL accreditation is recognized by the World Health Organization and is one of the best in the world. In addition to general requirements， such as quality management systems， laboratory personnel are tested on their knowledge of methodology and analytical techniques.
If you need to send samples outside your home country， it's important to know where those samples will be analyzed．For example， if you need blood work done in Singapore， make sure the laboratory can handle the type of specimen you need.
Many countries have government regulations about which tests must be performed in-country and which may be sent abroad for analysis. You should check with local regulators in both the U.S. and the country in which the test will be performed to ensure compliance with all rules and regulations.
