Immunology / Serology / STD / Allergy


The Immunology & Serology section provides services for Autoimmune serology, Allergen-Specific IgE serology, Infectious Diseases serology and Sexually Transmitted Diseases (STD) serology.

For serological tests for toxoplasmosis and legionellosis, paired sera (acute and convalescent; at least two weeks apart) should be sent. However, antibodies to some infections may take a longer time to develop (e.g. Legionella infections), such specimens should be taken a month to 6 weeks apart. Results for the first specimen are always despatched when ready, and this specimen is kept so that it can be run in parallel with the second specimen when it arrives. Interpretation for single specimens are always presumptive and do not carry the same weight as a rise in titre between the two specimens.

For further inquiries on tests and interpretation of results, laboratory users should call Client & Specimen Management, who will direct the inquiry to the technical and professional staff in the Section.

Stat results are only available for syphilis screening test (VDRL/RPR) for potential organ donors.

Turnaround time is based on the number of working days.
