  • RPR and TP antibody for Syphilis.
  • HIV EIA screening test for HIV infection.
  • Hepatitis B surface antigen and antibody.
  • Dark-Ground Microscopy for Treponema pallidium.
  • Type-specific serological testing for Herpes Simplex Virus anti-glycoprotein G antibodies to HSV-1 and HSV-2 for aiding in the diagnosis of HSV infection.
  • Specimen Collection Service
  • A transport service for collection of specimens for private dermatologists in Singapore is provided by National Skin Centre. Please call 6350 8436 for appointment.

A short clinical history will help in the clinicopathological correlation and in the interpretation of test results. The referring clinician and the contact number of the clinician or person to contact should be provided.

Transport Media

  • Specimens for histology should be sent in 10% formalin within 7 days of biopsy.
  • Specimens for direct immunoflurescence studies should be sent in Michel’s holding medium within 7 days of biopsy. The holding medium is provided by NSC laboratory upon request and can be dispatched to the referring clinic or hospital in advance. For centres outside Singapore, a charge on postage will be levied.
  • Blood specimens (5 mls) for indirect immunofluorescence studies can be sent in plain tubes.
  • Specimens or PCR assays can be sent as routinely processed specimens, either formalin-fixed tissue or processed paraffin blocks. Processed paraffin blocks will be returned to the referring centre.

Reports

  • A faxed histology report is available, usually within 3 working days of specimen collection. Allowance should be made for cases requiring further sections, special stains or immunohistochemistry.
  • Reports for immunofluorescence are available within a week of specimen collection.
  • All faxed reports will be followed by post.
