Complementary Test-Recommendations

CD3+/CD56+/CD57+/CD45+ NK-Cells (Immune-Status), Zonulin and Vitamin D3.

Elderly people and patients with underlying medical conditions such as hypertension, cardiac issues or diabetes, cancer, another active infection and/or those suffering from immunosuppression are more likely to experience more severe symptoms of COVID-19 [1],[2],[3]

NEW Symptom-Checklist for COVID-19 available - DOWNLOAD THE CHECKLIST

The COVID-19 Symptomchecklist is a supportive tool in the clinical diagnosis of the practitioner/therapist.
It does not replace a detailed clinical diagnosis.

We therefore additionally recommend checking innate (CD3+) and natural killer cell (CD56+/CD57+) immune status, as well as other parameters related to current immune status:

- Zonulin

- Vitamin D3

- CD3+/CD56+/CD57+ NK-Cells

Please draw 1 x EDTA tube and 1 x Heparin tube (both are included in the testkit - Please do not spin or cool any tubes!).

CD3+/CD56+/CD57+ NK-Cells: Documentation on immunity in viral infections and innate immunodeficiency

T cells (CD3+):

Elevated in:

  1. Acute viral infections (Covid-19?)
  2. In bacterial infections in the recovery phase, and fungal infections
  3. Immune therapies/immune stimulation

Low in:

  1. Chronic viral infections (EBV, CMV, HSV1/2, VZV, etc.)
  2. Innate immunodeficiencies
  3. Immunosuppressive therapies (e.g., glucocorticoids, steroids, cytostatic agents)
  4. Autoimmune diseases
  5. Kidney insufficiency

NK cells (CD56+NK cells):

Elevated in:

  1. Acute viral infections (Covid-19?)
  2. Immune therapies/immune stimulation
  3. Autoimmune diseases

Low in:

  1. Chronic viral infections (EBV, CMV, HSV1/2, VZV, etc.)
  2. Innate immunodeficiency
  3. Rheumatoid arthritis
  4. Smokers
  5. Heavy physical exertion
  6. Low-calorie diet

NK cells (CD57+NK cells):

Elevated in:

  1. Chronic viral infections (EBV, CMV, HSV1/2, VZV, etc.)

Low in:

  1. Chronic bacterial infections (Borrelia, Chlamydia, Mycoplasma, etc.)
