Standard Operating Procedures (SOPs) are an essential part
of good laboratory practices. These provide a stable pattern of function by
the laboratory staff and ensure consistency of quality in laboratory results.
SOPs are also a prerequisite for accreditation of laboratories. WHO has been
providing technical support in various laboratory technologies by providing
guidelines for the development of SOPs. Guidelines on Standard Operating Procedures for Laboratory
Diagnosis of HIV-Opportunistic Infections is another step in this
direction.
HIV/AIDS is perhaps the most important challenge being
faced by the human race. In spite of considerable efforts and inputs,
specific antiviral therapy that is accessible and affordable to the growing
number of HIV/AIDS cases in developing countries could not be provided so
far. These patients with a weakened immune system contract opportunistic
infections. It is estimated that the problem will confront Member Countries
of the South-East Asia Region with greater vengeance in the days to come. An
early diagnosis of these infections is of vital importance for better
management and initiation of preventive measures.
Opportunistic infections differ from conventional communicable
diseases and have assumed importance only after the advent of HIV/AIDS.
Understandably, the expertise for the diagnosis of these infections is
sub-optimal in the developing countries. Guidelines on
Standard Operating Procedures for Laboratory Diagnosis of HIV-Opportunistic
Infections is aimed at providing technical support to laboratories
that are involved in diagnosing opportunistic infections. On the basis of
these guidelines, the laboratories need to develop their SOPs and train their
staff in their effective use. Periodic review and updating of these SOPs in
the light of new knowledge and technology are also suggested.
I am sure this publication will meet its intended
objectives and help mankind in its fight against the menace of HIV/AIDS.
