Anemia Panel A
Test Overview
The Anemia Panel A is a diagnostic set of blood tests used to evaluate the underlying causes of anemia, a condition characterized by a deficiency in red blood cells (RBCs) or hemoglobin, which impairs the body’s ability to transport oxygen. This panel typically includes tests for iron levels, vitamin B12, folate, and other essential factors that influence red blood cell production and function. The results help identify the type of anemia and guide appropriate treatment strategies.
Test Types
- Iron Studies (Iron Panel): Assesses iron levels, ferritin, and transferrin, which are crucial for red blood cell production.
- Vitamin B12 & Folate: Determines deficiencies in these vitamins, which are important for red blood cell formation and function.
- Reticulocyte Count: Measures immature red blood cells, helping assess bone marrow response to anemia.
- Complete Blood Count (CBC): Provides an overall view of red blood cell count, hemoglobin levels, hematocrit, and mean corpuscular volume (MCV), which help identify the type of anemia.
Anemia Panel A Results & Ranges
| Test Component: | Normal Range: | Abnormal (Possible Anemia Type or Cause): |
|---|---|---|
| Hemoglobin (Hgb) | Men: 13.8–17.2 g/dL Women: 12.1–15.1 g/dL | Low: Anemia (Iron deficiency, B12 deficiency, etc.) |
| Hematocrit (Hct) | Men: 40.7%–50.3% Women: 36.1%–44.3% | Low: Suggests anemia, bleeding, or nutrient deficiencies |
| Red Blood Cell Count (RBC) | Men: 4.7–6.1 million/µL Women: 4.2–5.4 million/µL | Low: Anemia, bone marrow disorders, or blood loss |
| Mean Corpuscular Volume (MCV) | 80–100 fL | Low: Microcytic anemia (Iron deficiency, Thalassemia); High: Macrocytic anemia (Vitamin B12 or folate deficiency) |
| Serum Iron | 60–170 µg/dL | Low: Iron deficiency anemia |
| Total Iron Binding Capacity (TIBC) | 240–450 µg/dL | High: Iron deficiency anemia |
| Ferritin | Men: 20–500 ng/mL Women: 20–200 ng/mL | Low: Iron deficiency anemia; High: Inflammation, liver disease |
| Transferrin Saturation | 20%–50% | Low: Iron deficiency anemia |
| Vitamin B12 | 200–900 pg/mL | Low: Vitamin B12 deficiency anemia (Macrocytic) |
| Folate (Vitamin B9) | 3–17 ng/mL | Low: Folate deficiency anemia (Macrocytic) |
| Reticulocyte Count | 0.5%–2.5% of total RBC count | High: Bone marrow response to anemia (e.g., blood loss); Low: Bone marrow production issues |
Expected Turnaround Time
- Results Available: 1–2 business days
Specimen Requirements
- Sample Type: Blood sample (venipuncture)
- Container: Serum separator tube (SST) for iron and vitamin panels; EDTA (lavender-top) tube for CBC
Collection Instructions
- Fasting not required, but it’s recommended to avoid heavy exercise prior to the test.
- Avoid supplements or medications that may interfere with test results (such as iron supplements or vitamin B12) unless instructed otherwise by a healthcare provider.
- List of current medications and health conditions should be shared with the healthcare provider, as they may affect anemia results.
- Storage: Samples should be processed promptly for accurate results.
Test Details
Clinical Use: Identifies causes of anemia (e.g., iron deficiency, vitamin B12 or folate deficiency, chronic disease anemia). Monitors treatment effectiveness for conditions like iron deficiency anemia or vitamin B12 deficiency. Provides a comprehensive view of iron metabolism (ferritin, transferrin saturation) and vitamin levels to pinpoint the cause of anemia. Helps guide the treatment of nutritional deficiencies or bone marrow disorders that affect red blood cell production.
Limitations: Recent blood loss or iron supplementation may affect iron and ferritin levels. Vitamin B12 and folate levels can fluctuate depending on diet and supplementation. Chronic inflammation can cause elevated ferritin levels, which may be misinterpreted as normal iron stores.
The Anemia Panel A is a key tool for diagnosing different types of anemia and identifying the root causes, enabling tailored treatment plans for improving red blood cell production and overall health.
