Although it is not a part of the egg freezing treatment, you will be tested for any infectious diseases, like HIV and hepatitis. This is to work out if your collected eggs need to be stored separately to prevent contamination of other egg samples. The UK regulatory body (known as the HFEA) requires fertility clinics to carry out these screening tests.
Several screening tests will be carried out to check if egg freezing is suitable for you. These may include an ultrasound scan and blood tests (e.g. AMH, FSH) to check hormone levels. Some of the test results will be used to decide the treatment approach by your specialist . Depending on the results, further tests may be required.
