GCF
Also written as: GCF — Gingival Crevicular Fluid
Abbreviation for Gingival Crevicular Fluid, a serum-derived fluid found in the gingival sulcus used as a diagnostic biomarker.
Full Definition
GCF stands for Gingival Crevicular Fluid, a transudate/exudate collected from the gingival sulcus that reflects the inflammatory status of the periodontium. It is extensively studied in periodontal research for cytokine profiling, protease activity, and microbial analysis. In clinical manuscripts, GCF should be spelled out in full at first mention with the abbreviation in parentheses. Editors reviewing periodontal or implant research papers should verify that GCF collection methodology (Periopaper strips, microcapillary tubes, washing method) is described in the Materials and Methods section. Variations in collection protocol affect comparability of results and should be flagged if inconsistently reported.
Usage
Usage note: Spell out in full at first use. Confirm the collection method is described if GCF data are cited as primary outcome measures.
