Medical Order for Lab Tests
What is a Medical Order?
A medical order (also called a doctor’s prescription) is a document issued by a licensed healthcare professional that specifies which blood tests a person needs to have done.
This blog guides the laboratory on which tests to perform, whether to prevent diseases, carry out a routine check-up, or evaluate a specific symptom or diagnosis.
Additionally, a medical order ensures that the requested tests are appropriate based on the patient’s overall evaluation, and in many cases, allows the cost of the tests to be covered by health insurance or a private plan.
However, not all blood tests require a medical order. Nowadays, many laboratories offer the option to perform preventive check-ups or routine tests without a prescription, making it easier to access preventive care and health monitoring.
Why Are You Sometimes Asked for a Medical Order?
It’s common for patients to have questions when visiting a blood testing laboratory: some labs require a medical order, while others allow certain tests without it. In reality, not all tests require a prescription, and it depends on several factors: the type of test, the lab policies, and whether the test is covered or not by insurance.
The main purpose of a medical order is to serve as a guide for the lab, clearly indicating what needs to be evaluated and monitored in each patient. It is especially useful when tracking a medical condition, monitoring disease progression, or assessing the effects of a new treatment or medication.
Therefore, even when it’s not mandatory, a medical order helps ensure that tests are properly oriented and that the results are useful for both the doctor and the patient.
When is a Medical Order Needed
Some blood tests do require a medical order, as the laboratory must verify that the request comes from a licensed healthcare professional or because the results have specific clinical implications.
This typically occurs when a test is part of a diagnosis, treatment follow-up, or to monitor the response to a new medication that may have side effects and requires closer evaluation.
Before undergoing any test, whether at a laboratory near you or through a home blood collection service, it’s always recommended to check in advance if a medical order is required.
Additionally, some tests may need a medical order if the patient intends to submit it for reimbursement with insurance or to meet insurance coverage requirements.
When is a Medical Order NOT Needed
Many labs allow blood tests without a medical order, especially for preventive check-ups or routine health monitoring. This means that patients can choose which tests to take on their own, without visiting a doctor first.
