Test Requests

Familiarisation with Pathology Laboratory Services on the availability of the types of tests in the different disciplines, laboratory operating hours, laboratory collection service, types of emergency/stat tests and many others would be very useful prior to placing test requests.

Specimens are to be submitted together with authorised Test Request Forms or electronic requisition, or written requests with authorised requestor's name. Self-referral by patient or direct to consumer testing will not be accepted.

Types of Tests


Please refer to 'View Test Listing' to view all the tests available in Pathology Division, either alphabetically or by categories.

Test Request Form


If Test Request Forms are used, please use the correct test request form to accompany the patient’s sample so that it can reach the appropriate laboratory without unnecessary delay. Tick the appropriate box/boxes on the request form. To order tests that are not listed on the form, write the name of the test in the space marked "Miscellaneous" or "Others".

"REQUEST FOR LABORATORY SERVICES" form can be used for private referrals (e.g. by General Practitoners).

All information requested in the form should be given as this is essential for proper processing of samples and correct interpretation of test results. The following forms are used in Singapore General Hospital when requesting for various laboratory tests.

Samples of these forms can be viewed in the section under the heading Test Request Forms.

  • Patient’s NRIC number or Passport number
  • Hospital Registration or Account number
  • Date of birth
  • Sex
  • Nationality
  • Others, e.g. first twin or second twin

  • Name of Hospital
  • Name of Clinic/Department
  • Ward number
  • Bed number

Non-hospital or clinic clients should include the name, address and telephone number of their organisation. An e-mail address and Fax number should be included if available for alternative means of communication. It is important to include the name of the contact person in the organisation for the return of reports, and the name and contact number/e-mail address of the requesting doctor for discussion of the case if this is needed.

Name of Requesting Doctor/Consultant/Authorised Requestor


This information is important for the laboratory to contact the relevant physician/authorised requestor when necessary. The MCR number of the requesting physician should be included if hard copy test request is used. The specimen may be rejected if the requesting physician's name is not given.

Clinical History


  • Clinical diagnosis
  • Suspected disease/organism

  • Any previous test results with dates and previous laboratory numbers
  • Patient’s immune status (e.g. any underlying diseases, cancer chemotherapy, immunosuppressive treatment)
  • Any other relevant patient or clinical data requested in 'Special Instructions' of each laboratory discipline.
  • Specimen may be rejected if no diagnosis or clinical history is given. This applies especially to Histopathology, Cytology, Cytogenetics and Virology investigations

Nature of Specimen


Identify the specimen source by indicating the specific body site from which specimen had been taken.

Persons who coordinate the collection of specimens at sites remote to the SGH Campus must be aware that there are tests that have unique or stringent requirements and are therefore not suitable for collection outside the SGH Campus or other SingHealth institutions. Such specimens, if collected, will be rejected. Please refer to the following tables for specimens that can/cannot be collected at SingHealth Polyclinics and by Alternative Phlebotomists, respectively.

  • Specimens collected at Singhealth Polyclinics Laboratories for SGH Campus Institutions. Click here for details.

  • Specimens collected at Singhealth Polyclinics Laboratories for KKH. Click here for details.

  • Specimens collected at Singhealth Polyclinics Laboratories for CGH. Click here for details.

  • Specimens collected by Alternative Phlebotomists (Personnel who are not designated staff of SGH or Referring Institution/Clinic/Physician). Click here for details.

A consent form must be completed for all alternative phlebotomy services, to be signed by the phlebotomist and the patient. For patients under 21 years of age, or patients who lack the capacity to give consent, a separate consent form needs to be completed and signed by the phlebotomist and the patient’s legal representative. Click here for the two forms. Specimens collected by alternative phlebotomy service and not accompanied by the appropriate consent forms will not be accepted.

Date and Time of Specimen Collection


The actual date and time of specimen collection should be indicated for proper evaluation of test results.

Emergency or Stat Test


Clearly indicate this on the test request. Make sure that the telephone numbers of the named person to whom results should be given are provided.
