# PID Types

## Waht is a PID Type?

PID (Patient IDentification) Type is a scheme of identification of the Patients. Depending on a country where iLab is used, different kinds of PID Types are applicabble. Ussually, PID types are [National Identifiers](https://en.wikipedia.org/wiki/National_identification_number). The pair PID Type and PID are unique in iLab.

## Anonymous Patients

Anonymous Patient in iLab is refered to a patient, which has not such identifier (PID Type = 0). In that case, Patient  is treated as not idetified and it hasn't its own patient file in the system. Anonymous patients are *per Sale*, they can't be reused in different Sales. Every visit of such a person leads to creation of a new Patient object.
