Phenol Red Thread Tear Test (PRT-TEST) is developed based on the Schirmer Tear Test. It is a special cotton thread impregnated with phenol red dye. Phenol red is pH sensitive and changes from yellow to red when wetted by tears. This test can indicate the function of the tear secretion easily with its stable colour and water-absorbing ability. The PRT-Test is sometimes also called the “Colour Bar Schirmer Tear Test” and may be useful tool to detect dry eyes.
The product is CE certified and the packing consists of 100 sterile threads per box (2 threads/transparent pouch and 50 pouches/box).
