“Huge shoutout to Wafa at Quest Diagnostics in Chelmsford!
I have very difficult veins, and it usually takes multiple attempts and sometimes multiple phlebotomists to successfully draw blood. But Wafa is truly exceptional. Last week, she got it on the very first try with absolutely no pain.
Today was another example of her skill. One phlebotomist was unable to draw my blood and had to pass it on. When Wafa stepped in, she again got it on the first attempt, it was quick, smooth, and completely painless.
Her expertise, confidence, and gentle approach make such a difference for patients like me. I’m incredibly grateful and hope she gets the recognition she deserves!”
“Outstanding Laboratory with Unparalleled Accuracy and Service
Fantastic Lab is, without question, the most reliable breath-testing laboratory in the world. While many other labs suffer from frequent reliability and reproducibility issues — often due to inadequate analysis of raw gas data and the use of inconsistent or symptom-dependent reference ranges.
Aerodiagnostics maintains the highest possible standards at every step.
They exclusively use genuine QuinTron collection kits (many labs skip this step), ensuring that every patient sample remains viable from collection to analysis. The analyser is meticulously calibrated before and after each test, and no shortcuts are ever taken.
What truly sets this lab apart, however, is the personal involvement of the owner, Gary. He routinely reviews complex or nuanced results himself and is always willing to discuss reports in detail with both practitioners and patients. His expertise, responsiveness, and genuine commitment to accuracy are unmatched.
If you need breath testing (SIBO or fructose, lactose, or sucrose malabsorption) that you can trust, Aerodiagnostics Lab is in a league of its own. I would highly recommend this without any reservation. We have ran thousands of samples with them”

“Benny was the most amazing phlebotomist I have ever met. Incredibly kind and such a calm presence to have when getting blood drawn.

“Here is another great experience with Pooja P. She is excellent at what she does and she makes it easy for it to be done. If I was anyone who want to get there blood draw and draw with a good phlebotomist she is the person to go too. She has the heart for her work and cares about everything she does and for the people who come to see her to get there medical blood work done for there health. Anyone who need a great blood drawn in Waltham or in Massachusetts in general I would recommended this awesome person that gives it her all to be great to patient everyday. Keep up the great work I’ll be returning and hope others listen and follow my steps since she is the best!!”
“Recently required a heart monitor. Was recommended my major boston hospital that first call was a family run business and was very trustworthy. After picking up the First Call . Sandra from their office called and said already used one in six month insurance covered monitor. I wanted to use them instead of I Rhythm. Which btw has a F rating with BBB . Sandra did all the rechecking and saved me money. Great company. Thank you Sandra and First Call Medical.”
“They’re the best @blood work I’ve had. Quick & Painless. I walked in @7:30, was out by 7:40.
I have no idea why they’re rated so low, but this is my second time coming here and I loved both times. Specially with the butterfly for bloodwork.
Thank you!”
“Great service and amazing professionals! Very grateful to Tara and Sherlanda (or Shirlanda, sorry!!!) who were not only kind but also excellent at what they do! ??”
“Forever grateful to Dr Musto and his staff! Dr Musto has found the cause of the pain and problems I’ve been going through for about 5 years. After seeing numerous other doctors, hospitals, labs & urgent care places, I thank Dr Musto for his knowledge and wisdom to help diagnose the problem. Highly recommend Dr Musto to anyone who needs a truly good and caring doctor! ❤️”
