SCC Antigen Unit Converter
Squamous Cell Carcinoma (SCC) Antigen is a subfraction of the tumor-associated antigen TA-4. It is a glycoprotein belonging to the serine protease inhibitor (SCCA) family.
Clinically, SCC Antigen is a valuable tumor marker for squamous cell carcinomas of the cervix, lung, esophagus, and head & neck. It correlates well with tumor stage and is primarily used for monitoring treatment response and detecting recurrence. This converter facilitates switching between the standard reporting units of ng/mL and μg/L.
Standard Mass Units
Most CommonNanograms per milliliter (Numerically equivalent to μg/L).
Other Equivalents
Clinical Context
Reference Values: Typically < 1.5 – 2.5 ng/mL (varies by assay).
Interpretation:
• Elevated: Squamous cell cancers, but also in benign skin disorders (psoriasis, eczema) and renal failure.
• Renal Failure: SCC-Ag is cleared by the kidneys; levels may be falsely elevated in patients with creatinine > 1.5 mg/dL.
Conversion Logic:
1 ng/mL = 1 μg/L.
1 ng/mL = 1,000 ng/L.

Frequently Asked Questions
Yes. 1 nanogram per milliliter is numerically identical to 1 microgram per liter.
SCC-Ag is generally not sensitive enough for screening early-stage disease. It is best used for monitoring treatment response.
