Several laboratory anomalies are associated with an increased likelihood of developing CIN (Figure 1), including alkaline phosphatase (ALP), alanine aminotransferase (ALT), carcinoembryonic antigen (CEA), nitrogen index, serum lactate dehydrogenase (LDH), and tumor necrosis factor (TNF), along with baseline white blood cell (WBC) count, hemoglobin, bilirubin, serum albumin, and serum creatine levels [2,8,9,14,18]. This evidence concerns the gene CEACAM5 and cervical squamous intraepithelial neoplasia.
