2.1.2 Genetic disease screening

The genetic disease screening must be conducted using a structured questionnaire prepared by the Medical Director or a qualified professional designated by the Medical Director.
The structured questionnaire to assess the risk of genetic disease transmission must include the following genetic disease screening criteria:
1. presence of a serious autosomal dominant, autosomal recessive, or X-linked genetic disorder in the sperm or ova donor; and
2. presence of a serious autosomal dominant, autosomal recessive, or X-linked genetic disorder in three generations of the sperm or ova donor's family genetic history.
In lieu of performing the genetic disease screening set out in Clause 2.1.2 (I) and (II), the results of the relevant genetic testing of the sperm or ova donor for the presence of one or more serious autosomal dominant, autosomal recessive, or X-linked genetic disorders, performed in accordance with Clause 2.3.1 (II), may be used to assess the donor for the risk of genetic disease transmission.
Based on the results of the genetic disease screening, an assessment of the risk of genetic disease transmission must be carried out by the Medical Director or a qualified professional designated by the Medical Director and the results of the assessment must be documented.

2.2 Physical examination

A physical examination of a sperm or ova donor must be performed by the Medical Director or a physician designated by the Medical Director. The results of a physical examination conducted within the previous six months, where indications of high-risk for infectious or genetic disease transmission were assessed, can be reviewed and documented in lieu of a new physical examination.

2.3 Donor testing

2.3.1 General

Each establishment engaged in conducting donor testing must develop Standard Operating Procedures (SOPs) that describe all infectious disease tests to be performed and the handling of positive and indeterminate test results.
Testing must be performed:
1. using appropriate and effective test methods;
2. by a laboratory that meets the accreditation requirements of the province in which the laboratory is located, or, in the case of imported sperm or ova, by a laboratory that meets a recognized equivalent accreditation requirement;
3. using screening or diagnostic test kits that are licensed:
  1. in Canada, if the testing is performed in Canada; or
  2. in Canada or the US, if the testing is performed outside Canada.
4. in accordance with the manufacturer's requirements for specimens, and the manufacturer's instructions for the performance of the test and interpretation of test results.
A sperm donor must be tested for the infectious disease agents set out in Clause 2.3.3 (I) (a), (b), (c), (d), (f), and (g) using donor screening test kits.
An ova donor must be tested for the infectious disease agents set out in Clause 2.3.3 (I) (a), (b), (c), and (g) using donor screening test kits.
A sperm or ova donor must be tested for the infectious disease agents set out in Clause 2.3.3 (I) (e), (h), and (i) using either donor screening test kits or diagnostic test kits.

A sperm donor must be tested for the infectious disease agents set out in Clause 2.3.3 (I), using specimen collected within seven days of obtaining the sperm sample. In the case of a sperm donor from whom a specimen has already been collected and for whom retesting is required under Clause E, it is not required to collect a specimen at the time of each donation.
An ova donor must be tested for the infectious disease agents set out in Clause 2.3.3 (I), except 2.3.3 (I) (d) and (f), using specimen collected within 30 days before obtaining ova or within seven days of obtaining ova.

2.3.3 Infectious disease agents

A sperm or ova donor must be tested for the following infectious disease agents:
1. HIV-1 and 2;
2. HCV;
3. HBV;
4. HTLV-I and HTLV-II (sperm donor only);
5. Treponema pallidum (syphilis)
  1. non-treponemal test; or
  2. treponemal-specific test.
6. CMV (sperm donor only);
7. WNV, if the donation is made during the time of year when WNV is potentially transmissible to humans in the donor's country of residence, or if in the preceding 56 days, a donor has lived in or travelled to an area where WNV is endemic;
8. Chlamydia trachomatis; and
9. Neisseria gonorrhoeae.
