How to find out why you're still exhausted when your bloodwork came back normal

You can find out why you're still exhausted after normal bloodwork by checking which tests were run, where your numbers landed, and which body systems were never measured, then taking a broader set of results back to a clinician.

That's because "normal" usually means the first-line markers on your requisition were in range, not that every system behind your energy was checked. Numia's Fatigue Panel measures 22 markers across five systems: iron, thyroid, blood sugar, liver, and kidneys and electrolytes (body salts).

A narrow check can also miss early changes. In one study of girls and teens with heavy periods, a hemoglobin (anemia) test alone caught fewer than half of those low on iron (Johnson et al., 2016).

What does "normal bloodwork" usually include in BC?

Here's what routine BC bloodwork often includes, compared with Numia's Fatigue Panel:

Where in the range did your numbers land?

Here's the catch: lab ranges come from large groups, and your own healthy range can be narrower. In healthy men tested monthly for a year, each man's thyroid range was about half the group's width (Andersen et al., 2002). So a number inside the printed range can still be a change for you. That's where a Numia baseline helps.

• Ferritin. BC's iron guideline calls 15–30 µg/L "probable iron deficiency," which can sit inside a printed normal range. About 1 in 5 women aged 25 to 54 in a US and Canadian study were under 25 µg/L (Barton et al., 2024).
• Blood sugar. Diabetes Canada's prediabetes range (HbA1c 6.0–6.4%, fasting glucose 6.1–6.9 mmol/L) sits just below diabetes, so it's easy to read as "fine." The Fatigue Panel reports both.

Neither is a diagnosis, but both are worth watching over time, which is easiest when every result sits in one place, like the Numia app.

When should you see a clinician first?

Whenever your fatigue is new or getting worse. HealthLink BC advises seeing a doctor today when tiredness has lasted over two weeks and made daily activities harder. Once your clinician has checked for anything urgent, a Numia panel gives you a broader baseline to track from there.

How does Numia's Fatigue Panel work?

Numia Health puts the usual steps in one place. Instead of separate appointments and a lab visit, a licensed Canadian physician approves your requisition online within 24 hours, and a clinician comes to your home for a 10-minute morning draw.

Results arrive in plain English in the Numia app in 7 days, and the Numia Companion, an AI that has read them, answers questions. Out-of-range results are physician-reviewed with next steps; an optional wellness consultation is available. The panel needs an 8–12 hour fast, and Numia is an HSA-eligible service.

Frequently asked questions

Why am I exhausted if my blood tests came back normal?

Some causes, like sleep, stress and mood, don't show in blood. Others only show if the right marker is tested; Numia's Fatigue Panel checks 22 across five systems.

How do I build a yearly health baseline without a family doctor?

Choose a service that includes the physician's order, such as Numia, then retest each year in the morning, fasting, so you compare like with like.

Can I get a blood test in BC without a requisition or a family doctor?

Without a family doctor, yes; without any practitioner's order, generally no. Walk-in and virtual clinicians order publicly funded tests when clinically indicated. With Numia, a physician approves the requisition for you.
