Why it matters
The problem this solves.
The challenge
Patients call to ask fasting rules – and sometimes just guess and arrive unprepared anyway.
What it costs
Failed draws mean repeat visits, wasted phlebotomist time, and frustrated patients who blame the lab.
The Chatref way
Chatref answers the exact prep requirement per test type from your knowledge base, 24/7.
The Chatref solution
How Chatref delivers prep instructions.
A patient asks whether they need to fast before their lipid panel. Chatref looks up the test in your configured prep content and returns the exact fasting window, hydration guidance, and medication notes – so the patient arrives on time and prepared.

How diagnostic labs use Chatref to deliver the right prep instructions before patients arrive.
Our failed-draw rate dropped because patients actually arrive prepared. Chatref answers the fasting question exactly right for each test type from our own content – not a generic answer that leaves patients guessing.
The morning prep call queue used to spike before opening. Now patients check their instructions the night before and arrive ready.
It delivers our exact fasting windows and medication guidance per test, in our own voice. Patients trust the answer because it matches what we tell them in person.
of prep questions answered before the patient calls the front desk
One knowledge base covers prep for every test we offer. We updated it once and stopped getting 'can I drink coffee' calls entirely.
Can it give different prep rules for different tests?
Yes. Your knowledge base holds the prep rules per test type, and Chatref surfaces the correct one when a patient names their test.
What if a patient doesn't know the name of their test?
Chatref asks clarifying questions to identify the test from your content before returning prep instructions.
Does it cover medication hold guidance?
Yes, as far as your prep content goes. Chatref surfaces whatever medication notes you have configured per test.
Can patients ask about water and coffee before a fasting draw?
Yes. Hydration and beverage questions are among the most common, and Chatref answers them from your configured prep rules.
How do I keep prep instructions current?
Update your knowledge base source and Chatref re-indexes the changes in minutes – no code changes needed.
Make 'am I prepared?' a question patients answer themselves.
