"Can I get my hormones checked, and will OHIP pay?" is one of the most common questions Ottawa patients bring to their family doctor, and to our front desk. The answer depends less on the hormone than on who orders the test and why. This guide covers the hormone tests most often requested, testosterone, estradiol, FSH and LH, prolactin, and cortisol, what Ontario's lab schedule says about coverage, and the timing details that make results meaningful.
Which hormone tests OHIP insures
Ontario's Schedule of Benefits for Laboratory Services lists total testosterone, free testosterone, estradiol, FSH, LH, prolactin, progesterone and cortisol as insured laboratory services. Unlike vitamin D or PSA, none of these carries a listed-condition restriction. In plain terms: when a physician, nurse practitioner, midwife or other practitioner authorized under Ontario regulation orders the test for a medical reason and you present a valid Ontario health card, you are not charged.
Two situations are different. Tests ordered by a practitioner who is not on Ontario's authorized list are not insured, even if the test itself normally is; the Schedule states that claims referred by anyone other than an authorized provider are not insured services. And tests wanted for a third party, such as an insurer, an employer or a sports body, are never covered. In both cases you pay at collection and receive a receipt. For the broader picture see is your blood test covered by OHIP.
Testosterone
Testosterone is usually measured when a patient reports symptoms such as low libido, erectile difficulties, loss of muscle, fatigue or low mood, or as part of monitoring hormone therapy. Levels are highest in the morning and fall through the day, so providers generally ask for an early-morning sample, and Canadian guidance recommends confirming a low result with a repeat morning test before drawing conclusions. If your requisition says morning, take it literally: come in when we open rather than after lunch. Our article on the role of testosterone explains what the hormone does in the body.
Free testosterone and sex hormone-binding globulin (SHBG) are sometimes added when the total result sits in a grey zone. Whether they are needed is your physician's call; the lab performs what is on the requisition.
Estradiol, FSH and LH
These pituitary and ovarian hormones are ordered for irregular or absent periods, fertility investigations, suspected early menopause in women under 45, monitoring fertility treatment, and some pituitary conditions. Timing within the menstrual cycle matters a great deal: an FSH drawn on day three of a cycle means something different from one drawn mid-cycle. Your provider will tell you which cycle day to come in, and it is worth writing that date on the requisition so our staff can record it.
Around the average age of menopause, hormone tests are often less useful than people expect. Canadian menopause guidance notes that in women over 45 the diagnosis is made from age, cycle history and symptoms, and that FSH and estradiol fluctuate too much during perimenopause to be reliable. If you are in that age range and your provider has not ordered hormone tests, that is usually a considered decision rather than an oversight.

Cortisol
Cortisol is the body's main stress hormone, and it follows a strong daily rhythm: highest shortly after waking and lowest around midnight. A single cortisol drawn at a random time of day is rarely interpretable on its own, which is why the test is usually ordered for a specific time, most often first thing in the morning, or as part of a structured protocol arranged by an endocrinologist. If your requisition specifies a collection time, arriving outside that window can make the result unusable. A blood cortisol is not a test for "adrenal fatigue," which is not a recognised medical diagnosis; if stress and tiredness are the concern, your provider will usually start with a more general set of tests.
Thyroid hormones
TSH, free T4 and free T3 are technically hormone tests too and are among the most common tests we run. They are insured, need no fasting, and have their own guide: TSH and thyroid testing in Ottawa.
Preparing for hormone bloodwork
- Follow the timing on your requisition exactly: morning for testosterone and cortisol, a specified cycle day for FSH, LH and estradiol
- Fasting is not usually needed for hormone tests alone, but if a fasting glucose or lipid profile shares the requisition, the fasting rule applies to the whole visit
- Tell staff about hormone medications, including patches, gels, injections and the contraceptive pill, and note when your last dose was; your provider needs that to interpret the result
- If you take high-dose biotin supplements, mention it to your provider; biotin can interfere with some hormone assays and they may ask you to pause it beforehand
- Bring your Ontario health card and your signed requisition, valid for six months from the date it was authorized
Making sense of results
Hormone reference ranges depend on sex, age, time of day and, for some tests, cycle phase or menopausal status, so the range printed on your report may not be the same as the one a friend was given. Results outside the range are not a diagnosis on their own; your physician interprets them alongside symptoms, examination and often a repeat test. Patients who are monitored over months, for example on testosterone therapy or during fertility treatment, may find the trend view in the Bio-Test app useful, since it shows each result against the lab's own range across visits.
Having hormone tests drawn in Ottawa
Hormone tests are ordinary blood draws, collected on a walk-in basis at all 11 Bio-Test centres across Ottawa-Carleton and Eastern Ontario. Because timing is so often part of the instructions, booking a morning slot online is a sensible way to guarantee an early draw. Review our preparation checklist before you come, and if any test on your requisition may be uninsured for you, ask at the desk so there are no surprises.
