Dr. Donovan's Daily Hair Loss Blog (2011-2019)

BLOOD TESTS

What blood tests do I need to get done?

We are often asked what blood tests are needed.  In general, we strongly encourage individuals with hair loss to see their own general physician or dermatologist first for an initial appointment about their hair loss and to order blood tests.    Dr. Donovan does not order blood tests for individuals prior to their first appointment as they have not yet become his patients (a doctor can only order tests for his or her own patients). 

Please keep in mind that the Donovan Hair Clinic is a private clinic and patients needing blood tests will be given a standard requisition to visit a local lab. However, because our clinic is private, these fees for blood tests will NOT be covered under provincial plans (MSP, OHIP, Alberta Health, Saskatchewan Health). Typical fees vary from province to province and an estimate can be found here:

Where should I get my blood tests done?

Dr. Donovan recommends any commercial lab nearby to where a patient lives.

 

Is there a fee for blood tests ordered by Dr. Donovan?

Because our clinic is a private clinic, there may be additional fees for any blood tests that Dr. Donovan orders.
