Thank you for sharing your recent blood test results. Low levels of hemoglobin and red blood cells can indicate anemia, which can be caused by various factors. While a diet high in iron-rich foods like beef can help prevent anemia, there may be other reasons for your low levels despite your dietary.

I will now your symptoms and test results to come up with a differential diagnosis using the latest tools and medical knowledge:

1. Iron deficiency anemia: Despite consuming a high amount of beef, there is a possibility that you may not be absorbing enough iron from your diet. This could be to gastrointestinal disorders or other underlying conditions.

2. Chronic disease anemia: Some chronic diseases such as kidney disease or certain cancers can lead to anemia by affecting the production of red blood cells.

3. Hemolytic anemia: This type of anemia occurs when red blood cells are destroyed faster than they are produced. It can be caused by autoimmune disorders, infections, or certain medications.

4. Vitamin deficiency anemia: In addition to iron, deficiencies in other vitamins like B12 and folate can also cause anemia.

To further narrow down the possible causes, I would recommend additional tests such as:

- Complete blood count with differential to check for any abnormalities in white blood cells and platelets.
- Serum iron studies to assess the iron levels in your blood.
- Vitamin B12 and folate levels to rule out deficiencies.
- Bone marrow biopsy if necessary to evaluate the production of red blood cells.

Incorporating both AI tools and traditional diagnostic methods will help in identifying the underlying cause of your anemia accurately. It is important to consult with a healthcare provider for a comprehensive evaluation and appropriate management based on the final diagnosis.
