Genetic tests for infertility: Karyotype, Cystic Fibrosis and Y microdeletion
Prostate Specific Antigen (PSA)
Most lab testing can be performed at any of the public or hospital laboratories. The generic requisition we print for you will be accepted at any of these labs. No matter which lab you go to, the quality of testing is the same. Almost all laboratory testing is covered by the public health plan. We will let you know if additional charges are anticipated.
Please complete your tests as soon as possible after your receive the requisition unless we request that you do it at a later date. Most test results are available within a few days of doing the test but some types of tests take much longer. It is important you go for the test as soon as possible to avoid unnecessary delays in your treatment. Some tests which take longer to obtain results include:
Karyotype and Y-chromosome microdeletion tests for infertility: up to 3 months
Stone analysis: 2-3 weeks
Urine cytology: 2-3 weeks
Most of the lab tests we order require absolutely no preparation (e.g. fasting). On the occassions where specific preparation is required, we will let you know. You can also check on the Lab Web sites and the Conditions and Health Topics section of our site for more information on your condition and some of the tests we do for diagnosis and treatment. Tests which do require special preparation include:
Your requisition will be accepted at any laboratory including BC Biomed, Life Labs and the hospital labs. Please note that there are a few lab tests (e.g. semen analysis) which are only accepted at specific sites and at specific times. Please refer to the websites for up to date information
Hospitals: unless we specifically request that you have a lab test done at a hospital, please have the test done at your local BC Biomed or Life Labs. Most hospital laboratory testing is restricted to inpatients or prior to upcoming surgery.

Imaging tests include things such as X-rays, ultrasounds, CT scans, MRI, and nuclear medicine scans. We will take care of sending the requisition to the imaging centre. Following this, the imaging centre will contact you, schedule a time for your test and give you instructions if preparation is necessary. We do not have any control over when the imaging labs schedule your test. If you have concerns regarding wait times, we recommend that you contact the imaging centre first before contacting us.
We have included info on some of the most commonly performed tests which require preparation. Please be aware that this is not a comprehensive list and the preparation may not apply to your specific circumstances.
Preparation for CT scans WITH CONTRAST
You will require a blood test (Creatinine) to ensure that your kidney function is satisfactory before undergoing the scan. If you have impaired renal function, you may be asked to take acetylcysteine prior to your test. If you are on METFORMIN, you will be given specific instructions by Radiology on when to stop and resume this medication.
Preparation for Biopsies (Prostate and Kidney)
Biopsies of the kidney and prostate take core samples using a needle. While the risk of bleeding is low, there is always some risk. Testing you ability to clot and discontinuation of medications which inhibit clotting may be necessary.
1. Lab testing: INR/PTT and CBC within 1 month of the procedure. If Coumadin/warfarin is used, an additional INR/PTT is required within 24 hours prior to the test
2. Antiplatelets and anticoagulants.
Post-ESWL X-ray (KUB): if you are being seen following Extracorporeal Shock Wave Lithotripsy at our Richmond Office, you may have your X-ray done downstairs in the adjoining building. Please arrive approximately 30 minutes early to our office to pick up your requisition.

We are commonly asked about safety and radiation exposure by patients undergoing tests. The American College of Radiology and the Radiological Society of North America have information on radiation exposure and the associated risks. We do not order unncessary tests and attempt to balance the benefits and potential harms of the tests we order. It is important to consider the potential harms from imaging studies in the context of the the background exposure to radiation from the environment and the overall risks of cancer. Please contact us if you have any questions or concerns.
Note that a CT KUB has a radiation dose similar to an IVP - about 1.5-3 mSv
