C-Reactive Protein, high sensitivity (serum or plasma)
The C-reactive protein (CRP) blood test measures the level of systemic inflammation. Uncontrolled systemic inflammation places you at risk for many degenerative diseases such as heart disease, stroke, and even increased cancer risk.
- Reference Ranges:
- Low risk <1.0 mg/L
- Avg. risk 1.0-3.0 mg/L
- High risk >3.0 mg/L
- LE’s Optimal Range:
- Women <1.0 mg/L
- Men <0.55 mg/L
Interleukin-6 (IL-6) (serum)
This test is used to identify elevated levels of interleukin-6 (IL-6). Elevated IL-6 serum or plasma levels may occur in sepsis, autoimmune diseases, lymphomas, HIV/AIDS, alcoholic liver disease, cancer progression, Alzheimer disease, and in concert with infections or transplant rejection. Elevated levels of IL-6 may be associated with an increased risk of heart attack or stroke (Kanda 2004; Cojocaru 2009). It is a good idea to test values of IL-6 with other cytokines such as IL-1 beta, IL-8, and TNF-alpha.
- Reference Range: 0-15.5 pg/mL
Interleukin-8 (IL-8) (serum)
This test is used to identify elevated levels of IL-8. Elevated IL-8 levels are observed in psoriasis, rheumatoid arthritis, chronic polyarthritis, cancer progression, and hepatitis C. It is a good idea to test measures of IL-8 with other cytokines such as IL-6, IL-1 beta, and TNF-alpha.
- Reference Range: 0.0-66.1 pg/mL
Tumor Necrosis Factor-alpha (TNF-alpha) (serum)
This test is used to identify elevated levels of tumor necrosis factor-alpha. TNF-alpha levels may be elevated in sepsis, cachexia, HIV/AIDS, hepatitis C, transplant rejection, and various infectious and autoimmune diseases. It is a good idea to test measures of TNF-alpha with other cytokines such as IL-6, IL-8, and IL-1 beta.
- Reference Range: 0.0-2.2 pg/mL
