Here we present a case series of three patients with COVID-19 (coronavirus disease 2019) who had a cytokine panel that revealed elevation of interleukin-6 (IL-6) but normal levels of interleukin-10 (IL-10), interferon-gamma (INF-) and interleukin-8 (IL-8), in contrast to the cytokine signature described in severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS). Under or over - filling of the tubes outside of the 0.8 - 1.2 mL range may lead to erroneous results. QuantiFERON-TB Gold (QFT) is a simple blood test that aids in the detection of Mycobacterium tuberculosis, the bacteria which causes tuberculosis (TB). We recommend retesting of subjects with QFT results in the range 0.20-0.99 IU/ml to enhance reliability and validity of the test.

In addition, mitogen response was inversely correlated with C-reactive protein concentrations ( Figure 1 ). Quantiferon TB minus NIL: result 0.40 H, ref ranges 0.00-0.35 IU/mL. Competing Interests: The authors have declared that no competing interests exist. Results just above or just below the cut off thresholds can switch back and forth between a positive and negative interpretation. Most people with a positive TB blood test have latent TB infection. Centrioles are found in pairs of two in the cell, during cell division. Most indeterminate tests (n = 175/177) were due to low mitogen response (mitogen minus nil control, <0.5 IU/ml). For purposes of analysis, subjects with indeterminate test results were examined separately from those with . A mitogen serves as a positive control to assess the immune function in IGRAs. The TB antigen tube finding was interpreted if the values of nega - tive and positive control met the following criteria: nil <8.0 kIUl-1 and mitogen minus nil 0.50 kIUl . The NIL value represents nonspecific reactivity produced by the patient specimen.
