OnlineMedicalTesting (OMT) was established by Dr. Nandi Harrysingh M.D , a US Trained Internist, and Adult Physician and is Operated in conjunction with a Canadian based IT team. 

Dr. Nandi Harrysingh is the personal physician to The President of Trinidad & Tobago, His Excellency,  Anthony Thomas Aquinas Carmona S.C, O.R.T.T

 How it works: 

  • With STD Tests, your name is NEVER used. You will receive an order number which you will take to the lab of your choice. 

You can start browsing with the tests listed on the right      

OMT is a confidential medical testing service designed to help you take charge of your own health, and to assist in the prevention and early detection of disease. You will receive the highest quality service that is convenient, comprehensive and affordable.

  • Did you know that a Doctor's Request form is required for all tests (Blood or otherwise)? (That's a $200-$300 cost by itself).

  • This is where Online MedicalTesting (OMT) comes in. OMT allows you to select, order and pay for your blood tests right here from the comfort of your home, office or wherever. Once your payment is received, you will be emailed a confirmation Order Number which you take to the lab of your choice. You simply present this order number, have your sample taken, and your results will be emailed to you. You can then take the result to your doctor if you wish, or schedule a review (via the phone or in-person) of your results right here! Video Consultation is also offered.

  • OMT saves you time and money by combining 3 different visits into one, not to mention the convenience! 

- "Health is peace of mind". 

The field of Medicine and the way it is practiced should push to be ahead to its time, not wait to catch up with the rest of the world.
