Yes, you can buy a term plan without medical test.
But it's not recommended at all. Here's why:
Firstly, there's a high chance of your claim getting rejected.
See your medical test results help your life insurance company get a clear picture of your health and accordingly decide your policy premium.
Say you did not take these tests at the time of application. Later on, if the insurer realises that the cause of your death was a pre-existing medical condition, they may reject your term insurance claim.
Find out why term insurance claim gets rejected and its causes.
Buying term insurance with medical tests helps you ensure your nominee can easily claim your policy money with no hassles or chances of rejection.
Secondly: Term policies with no medical tests usually offer lower life covers
This is because the insurer doesn't know about any underlying medical conditions you may have that might increase your risk of death. So to compensate for this unknown risk, they may offer you a low life cover, compared to what you'd have gotten had you undergone the medical tests before buying a term plan.
This low life cover may not be enough to meet your family's needs.
And thirdly, medical tests are free of cost*
So why wouldn't you want a free health checkup that the insurer pays for?
