With the latest technology in analyzers comes the ability to generate the results electronically and graphically. In this case, the results will be sent via email electronically to the doctor. In many situations, results are printed and then faxed 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 the drawing of the blood and when the doctor gets the results can vary greatly, from as little as a few minutes to as much as several weeks. Urgency, geographic distances, processing schedules, complexity of the test, and other factors explain why it may sometimes take so long to learn your results.
