A robot could eventually conduct your blood draw at the doctor’s office
The US Food and Drug Administration has approved Aletta, a robotic device designed to perform blood draws automatically in outpatient settings, marking the first authorisation of its kind. The device is intended to ease pressure on clinics facing a shortage of trained phlebotomists, potentially speeding up one of the most routine procedures in American healthcare, though it still requires human supervision rather than working entirely unattended.
Aletta uses near-infrared light and Doppler ultrasound to locate a suitable vein, then automates the remaining steps of a blood draw, including applying a tourniquet, inserting and disposing of the needle, and applying a bandage. A qualified phlebotomist must initiate each procedure and oversee the device throughout, though one person can supervise up to three Aletta units simultaneously. The FDA said its approval was based on clinical data showing success rates comparable to or better than human phlebotomists, but no timeline has been given for when the devices might appear in doctors' surgeries.
- FDA approves Aletta, first robotic blood-draw device for outpatient clinics
- Uses infrared and ultrasound to locate veins automatically
- One phlebotomist can oversee up to three robots at once

Aletta is a robotic device that has just been approved by the US Food and Drug Administration to carry out blood draws in outpatient clinics, the first machine of its kind to get this sign-off. It is designed to find a vein, insert a needle, collect a sample and apply a bandage without a person doing each step by hand.
The device is being introduced partly to help clinics cope with a shortage of trained phlebotomists, the staff who normally carry out blood draws, which is one of the most common procedures in healthcare. It still needs a qualified phlebotomist nearby to start each procedure and watch over it, though that person can oversee several machines at once rather than doing the draw themselves.
The story matters because it touches on how far automation can go in everyday medical care, and whether machines can safely take over routine tasks that have always relied on trained human hands. It also raises practical questions, such as how widely the technology will be adopted and how quickly it might reach ordinary doctors' surgeries.
