Choosing the right CBC Machine for your lab depends a lot on your needs like your expected sample volume, budget, and the availability of quality service engineers of the brand in your location. If you expect low sample volume and have a budget constraint, you can go ahead with a 3-part machine. Again, if you expect high sample volume, have no budget constraints and want machine-interfacing automatic 5-part cell counters with reliable interfacing support can be the right machine for you. Mostly, total reportable parameters, price, amc, cpt (cost per test), local service support are considered before buying a cbc machine.
