When you submit your slides we will give you an estimate, but the times it takes depends on several things:
First, there might be other projects that are ahead in line. If we cannot start scanning your slides within a couple of days of receiving them, we will let you know.
Second, it depends on your slides and staining. Slides with colorimetric stains (IHC, H&E, colorimetric ISH etc.) are generally fast to scan. Fluorescently stained slides are much slower, especially if there is multiplex staining and the staining is weak. Many sections on each slide or large sections also take longer.
