When examining amniotic fluid under a microscope, arborization, or ferning, will be identified. A pH test can be performed of vaginal fluid. Amniotic fluid typically has a pH of 7.1-7.3, while normal vaginal secretions have a pH of 4.5-6.0. Causes of false positive pH tests include presence of blood or semen, alkaline antiseptics, or bacterial . Purpose: Analysis of ferning formation after tear drop desiccation on a glass slide has been applied as a simple method to examine tear normality and is referred to as the tear ferning (TF) test. Despite use of the TF test in clinical settings and in some animals, thus far no TF test protocol has been developed for the mouse model. The tear ferning (TF) test can be used to assess the quality of tears . In addition, objective methods have been used for tear fern analysis . The TF test can be used as a repeatable in vitro method to assess the quality of tears collected from humans and animals [15–18]. Tears, when dried, produce crystals in specific patterns known as ferns. Abstract. Background: The ocular ferning test is used as a diagnostic aid to evaluate patients with dry-eye disease. The ferning phenomenon is a dendritic growth form of dried tear fluid. The influence of temperature and relative humidity (rH) on the morphology of tear ferning patterns was investigated. Methods: Two microliters of tear fluid of 5 volunteers with .
