What is the cytokine ratio test?
This is a blood test done by various labs in the US including RFU Chicago. It is a measure of the ratio of pro-inflammatory cytokines (chemical messengers) to anti-inflammatory cytokines in CD3+CD4+ white cells (cells which make a lot of cytokines) in the blood. Higher ratios have been shown to be associated with a lower chance of live birth and are common in many inflammatory conditions (e.g., Crohns, IBS, arthritis, asthma), in cases where there is a DQalpha match and/or elevated NK activity. They may also be elevated under chronic stress or when you have an infection.
