With the latest technology in analysers comes the ability to generate the results electronically and graphically. The results are printed and then sent to the doctor. If the results indicate the patient may be very ill, the laboratory will call the doctor with the results.
The length of time between taking the blood sample and when the doctor gets the results can vary greatly, from as little as an hour to as much as several weeks. Urgency, distances, the complexity of the test, and other factors explain why it may sometimes take so long to get your results.
