[Ultra-weak luminescence of blood in cancer patients].
Ultra-weak luminescence of blood in 67 normal blood donors and 57 lung cancer patients was studied using the sensitive single photon counting system manufactured in China. The results showed that the blood emission intensity of lung cancer patients was higher than that of the normal blood donors with significant statistical difference (P less than 0.05). The characteristic peak of blue light ranging from 426.8 nm to 446.8 nm in lung cancer patients may imply that ultra-weak luminescence test be of value in the diagnosis of lung cancer.
