What laboratory tests should leukoplakia do

summary

Leukoplakia is a lot of diseases, including: vitiligo, albinism, sweat spots, tinea versicolor, white bran diagnosis and so on. Leukoplakia is not necessarily vitiligo, but vitiligo is leukoplakia. The diagnosis of this disease can be confirmed by clinical symptoms and signs combined with relevant examinations. The inspection required is as follows.

What laboratory tests should leukoplakia do

1. Histopathological examination. The synthesis of extracellular matrix components such as collagen and fibronectin increased. 　　

2. Hydroxyproline was determined. Hydroxyproline is the characteristic amino acid of collagen. Hydroxyproline exists in plasma in three forms: free, peptide bound and protein bound. Free and peptide bound hydroxyproline is the metabolite of collagen. 5% of hydroxyproline excreted in urine exists in free form. The content of hydroxyproline in serum and urine is related to scar area. 　　

3. Scar hardness was measured. The industrial scale indicator is refitted: firstly, a stainless steel round sleeve with a diameter of 12mm is made and fixed on the measuring shaft of the indicator, which is used as the base of the hardness tester, and the measuring shaft extends 5mm out of the base. Secondly, in order to make the elasticity of the indicator match the scar hardness, the internal spring of the indicator is replaced by another spring with greater elasticity, so that the telescopic movement of the spring drives the pointer to rotate.
