Normal value of squamous cell carcinoma antigen: Radioimmunoassay: <1.5μg/L.

The normal value of squamous cell carcinoma antigen is the reference value for clinical diagnosis of various squamous cell carcinomas.

Squamous cell carcinoma antigen is a glycoprotein isolated from cervical squamous cell carcinoma (referred to as squamous cell carcinoma) tissue. It is a squamous cell carcinoma tumor marker with good specificity. Squamous cell carcinoma antigen was first used to diagnose squamous cell carcinoma. In cervical cancer, lung cancer, head and neck cancer, serum squamous cell carcinoma antigen increases, and its concentration increases with the worsening of the disease. Determination of squamous cell carcinoma antigen can monitor the efficacy, recurrence, metastasis and prognosis of these tumors. Increased: seen in squamous cell carcinoma, such as cervical cancer, lung cancer, head and neck cancer; hepatitis, cirrhosis, pneumonia, tuberculosis, etc. are also increased.

There are some things to keep in mind when testing for squamous cell carcinoma antigen:

1. Do not eat greasy or high-protein food and avoid drinking large amounts of alcohol the day before blood collection. The alcohol content in the blood will directly affect the test results.

2. You need to be on an empty stomach before blood collection and do not eat after 8 pm the day before blood collection to avoid affecting the detection of indicators on the next day.

3. You should relax when having blood drawn to avoid blood vessel contraction due to fear, which will increase the difficulty of blood collection.
