A lab requisition form is an official medical order from a licensed healthcare provider that tells a laboratory or imaging center exactly which tests to perform. It serves as a referral, ensuring the tests are medically necessary. The form typically lists the following:

• Your personal details
• The specific tests or scans requested
• Provider’s signature and credentials. 

Without this form, most accredited labs cannot proceed with testing, as it guides the technical process and how results are reported to your doctor.

Yes, in most cases, you need a medical professional to authorize lab tests or scans. You can’t order an MRI or blood test independently without a doctor. Many healthcare systems require a doctor’s requisition for blood work and imaging. Some regions do offer direct-to-consumer lab testing services for basic blood work, but even those involve a physician in the background who reviews and officially orders the test for you.

Yes, our requisitions are signed by a licensed physician. Labs and the imaging centre will treat an online doctor’s requisition the same way as any other.

The validity of an ultrasound requisition varies, but many providers follow a standard validity period of about six months to ensure test relevance and patient safety. 

Some private imaging centres do offer direct-access X-ray services without a referral. But these options often mean paying out-of-pocket, choosing the scan yourself, and getting no guidance on whether it’s the right test. With Your Doctors Online, the process is thorough. You can connect to a licensed doctor within minutes, get a requisition for the exact type of imaging you need, and take it to any accredited clinic. Once your results are in, our doctors review them with you, explain the findings, create a treatment plan, and offer a doctor’s prescription if no in-person exam is required. 

You can get a requisition for a pregnancy blood test by consulting with a licensed doctor, who will assess your symptoms and decide if testing is appropriate. Pregnancy blood tests measure beta-hCG and come in two types: qualitative (confirms if you are pregnant) and quantitative (measures the exact hormone level to track early pregnancy or other conditions). Most accredited labs require a valid doctor’s requisition before performing either test. Start a virtual doctor visit to get your requisition within 5 minutes. 

This depends on the lab. Many labs and imaging centres now accept electronic requisitions or a faxed copy directly from the doctor’s office.

Healthcare professionals use a lab requisition to request laboratory tests such as blood or urine testing. In contrast, a medical prescription includes the medication that a doctor has prescribed you.
