Additional file 1 of Heme oxygenase-1 and neopterin plasma/serum levels and their role in diagnosing active and latent TB among HIV/TB co-infected patients: a cross sectional study

Additional file 1: Supplementary material. Standards were used to draw a standard reference curve from which the sample ODs were converted into HO-1 and neopterin concentrations in ng/ml.

附加文件1：补充材料。以标准品绘制标准参考曲线，借此将样本的光密度（Optical Density, OD）值转换为以纳克/毫升（ng/ml）为单位的血红素加氧酶-1（HO-1）与新蝶呤（neopterin）浓度。
