How an Anemia Test Is Done (And Which One You Should Take)


Order your lab requisition online — then bring it to a local lab to test for anemia.
If you’re constantly tired, dizzy, or short of breath, there’s a chance you might be anemic—and not even know it. Anemia affects how much oxygen your blood can deliver to your body, which can drain your energy, impair focus, and worsen other health conditions.
But how is an anemia test is done, and which test should you take to get clear answers?
As an acupuncturist and Traditional Chinese Medicine practitioner with over a decade of clinical experience, I’ve seen how overlooked anemia can be—especially among active people, menstruating women, and those dealing with chronic fatigue or poor recovery. Knowing your numbers is the first step to getting back your energy and performance.
What Is Anemia?
According to a 2025 review published in StatPearls, anemia is not a disease—it’s a sign that your body lacks healthy red blood cells or hemoglobin. It’s incredibly common and frequently missed, even though it affects oxygen delivery to every tissue in your body.
Common symptoms of anemia include:
- Fatigue or weakness
- Pale skin or cold hands and feet
- Brain fog or lightheadedness
- Chest pain or rapid heartbeat
- Shortness of breath during activity
Anemia can stem from iron deficiency, vitamin B12/folate deficiency, blood loss, or chronic illness. That’s why testing is so important—it’s not enough to guess based on symptoms.
So, How Is an Anemia Test Done?
Anemia tests are done through a simple blood draw. The most common way to screen for anemia is by measuring hemoglobin and red blood cell levels in a Complete Blood Count (CBC). However, a full workup usually includes additional markers to understand what’s causing the problem.
Key components in anemia testing include:
- Hemoglobin & Hematocrit: Measure oxygen-carrying capacity.
- Ferritin & Iron Levels: Check iron stores and transport.
- Vitamin B12 & Folate: Look for nutrient-based causes.
- Reticulocyte Count: Assesses bone marrow activity and red blood cell production.
These tests are often bundled into comprehensive anemia panels that assess the root cause—not just the symptom.
Recommended Anemia Tests
Here are some convenient and reliable anemia test panels you can order online without a doctor’s referral:
Basic Anemia Panel
Includes a Complete Blood Count (CBC) to evaluate red blood cell health and screen for anemia.
Comprehensive Anemia Panel
Includes CBC plus ferritin, folate, vitamin B12, reticulocyte count, and platelets—ideal if you want a deeper look at the cause of your fatigue or symptoms.
Ferritin Test
A great add-on to measure your iron storage protein and catch early iron deficiency.
Vitamin B12 & Folic Acid Test
Essential if you’re plant-based, recovering from illness, or have neurological symptoms.
Iron & TIBC Panel
Measures both iron levels and your blood’s capacity to carry it—important for ruling out iron deficiency anemia.
Sickle Cell Anemia Test
Recommended if you have a family history or are part of an at-risk population.
When Should You Test for Anemia?
The StatPearls article notes that there’s still debate in the medical world about who should be screened and when—but most agree testing is warranted if you have symptoms or risk factors like:
- Heavy menstrual cycles
- Vegan or low-iron diet
- Frequent blood donation
- Athletic training fatigue
- Family history of anemia or sickle cell
Routine blood work panels often miss nutrient deficiencies unless they’re specifically requested. So if you’ve been told your bloodwork looks “normal,” but you still feel off—it’s worth looking deeper.
Take Control of Your Health
Anemia isn’t just “low iron”—it’s a signal that your body needs attention. Whether you’re constantly fatigued or just curious about your iron and nutrient levels, these simple tests can offer real insight—and a clear path forward.
