COVID-19 Update: Episode 1 part 2

This is part 2 of a 2-part audio presentation, which was recorded on April 6th, 2020 to present some of the latest research around COVID-19. In part 2 we covered the following topics:

  1. What are some of the ways to assess optimal immune function?
  2. Blood biomarkers that might be helpful
  3. Other assessment techniques
  4. What are some of the treatments/recommendations for restoring/maintaining optimal immune function?
    • Ensuring optimal nutrient intake
    • Balanced and targeted nutritional supplementation
    • Avoiding drug-induced nutrient depletion
    • Stress management
  5. How do we test for zinc deficiency?
  6. A review of some of the testing for SARS CoV2 Virus - antigen, stool antibody, and serum antibody testing

Research Studies and Links

Here are some of the information, research studies, and links we refer to in the podcast:

Blood biomarkers that might be helpful

  • Comprehensive metabolic panel (including alkaline phosphatase, creatinine)
  • CBC with differential, total lymphocyte count (low with malnutrition but increased with viral infection (unless malnourished?)
  • NLR Neutrophil/lymphocyte ratio (higher with bacterial, lower with viral)
  • Total protein, prealbumin, albumin, globulin
  • hs-CRP, IL-6
  • Nutrients
    • Zinc serum and RBC, WBC zinc if available
    • Selenium serum
    • Magnesium serum and RBC, WBC if available
    • Iron Panel - Total Iron, TIBC, Transferrin, % Sat, ferritin
    • Vitamins A, C, 25-OH D, E, folate, B12, B1, B6
    • Omega-3 Index (optimal >8%)
