    It depends very much on the market and the regulation that applies. Generally speaking, the whole process can take from 6 to 18 months, but it depends very much on each individual case.

    It depends on the working hours invested in the project. Once this has been thoroughly analysed, an adjusted budget will be drawn up for the hours required to carry out the project.

    If the sales expectation for your test is more than 100,000 units per year, it is recommended to automate the production of your test. However, setting up a production plant requires a large investment in material and human resources, which could cost around one million euros. This, in cases where there is no absolute certainty as to what the final market sales figure will be, can entail a significant risk. In order to minimize it, another option would be to subcontract this production to a solid company of the sector, with experience in the manufacture and handling of similar products. From OPERON, we have a long experience that will facilitate this process enormously.

    It depends on the project. Each test is different both in size and in the materials it is made of. Some of them are sold in strip format, while most of them are sold in cassette format and with different cassette designs. In fact, several of these projects often require the tests to be compatible with the use of readers for the interpretation of results, which implies working with QR codes, reading cards or RFID tags.
