Several significant differences between the CRC and non-CRC groups were found; patients diagnosed with CRC after positive FOBT were found to have lower hemoglobin levels (12.8 ± 1.94 vs. 13.64 ± 1.7, p < 0.001), albumin (4.14 ± 1.5 vs. 4.23 ± 1.3, p = 0.018), iron (62.69 ± 174 vs. 76.7 ± 34, p < 0.001), and ferritin levels (101.36 ± 174 vs. 123.43 ± 38, p < 0.001). Here, ALB is linked to colorectal carcinoma.
