Cómo usar una variable en otra ruta en node.js

Tengo una ruta que crea una variable:

 app.post('/post', function(req, res){ var test = req.body.test //this is the var I want to use res.render('folder/ejs.ejs', { test: test}) return test })

Luego, en otra ruta de obtención, estoy tratando de insertar la cadena en una URL

 app.get('/get', function(req, res) { axios.get('https://www.randomletters.com/1234/' + test) .then((response)=>{ //.....

Cuando intento ejecutar esto, aparece el error ReferenceError: test is not defined . ¿Cómo puedo usar la misma var en diferentes lugares?
