Questions about Aletta®

Is Aletta® safe?

Yes, Aletta® has received regulatory approvals in the EU (CE mark) and in the US(FDA). Aletta® has performed more than 12,000 blood collections in the EU with no serious adverse events. All reported adverse events have been characterized as mild and have occurred at a lower rate than with manual phlebotomy.

Who can use Aletta®?

Aletta® is designed for patients of 16+ in phlebotomy settings in hospitals. Aletta® may not be appropriate for every patient or every blood draw. Suitability for an Aletta® blood draw is determined by the phlebotomy staff on site.

Who oversees my blood draw with Aletta ®?

A trained phlebotomist oversees the procedure and is available to assist you when needed. A trained phlebotomist can oversee up to three Aletta devices.

Will Aletta replace my phlebotomist?

No. Aletta is a complement to the phlebotomy team, not a replacement. A trained phlebotomist continues to oversee the procedure and is available to assist when needed.

Does Aletta® use anew sterile needle for each venipuncture?

Yes. Aletta automatically uses a new, sterile needle and blood collection set for each patient.

How does Aletta® find my vein?

Aletta uses multimodal imaging, including near-infrared imaging, ultrasound, and Doppler, to identify and select a suitable vein for blood collection.

Will Aletta® work with my skin tone?

Yes. Aletta uses multimodal imaging, including ultrasound, to identify a suitable vein. Ultrasound is not affected by skin pigmentation, and Aletta has been used successfully in patients across a range of skin tones.

Is Aletta® precise and accurate?

Aletta uses multimodal imaging to identify a suitable vein and AI guidance to position and insert the needle with submillimeter (0.02 mm) robotic precision.

What does an Aletta® blood draw feel like?

Patient experience may vary, but 90% of patients report that an Aletta blood draw is less painful than or similar to a manual blood draw.

What if I am nervous or need help during the blood draw?

A trained phlebotomist oversees the procedure, and you can use the help button at any time to request assistance.

Can I stop the blood draw at any time during the procedure?

Yes. You can stop the procedure at any time by pressing a red stop button located on either side of the device or by pressing the help button located in front of you.

What happens if Aletta® cannot find a suitable vein?

If Aletta does not identify a suitable vein, it will not attempt a venipuncture, and the procedure will stop. The phlebotomy staff overseeing the procedure may recommend scanning your other arm with Aletta or determine the appropriate next steps.

I'm difficult to puncture. Can I use Aletta®?

Aletta may be an option for patients who have experienced difficult blood draws or required multiple attempts in the past. In peer-reviewed published clinical studies, Aletta has demonstrated 94.5% first-stick success overall, with a 92.7% success in patients with difficult venous access after a suitable vein was identified. Aletta uses multimodal imaging to identify and select a suitable vein for blood collection.

Can patients that use blood thinners use Aletta®?

Patients taking blood thinners may use Aletta. After the blood draw, standard post-venipuncture care is provided, including the application of a bandage and pressure to the puncture site, similar to a manual blood draw.

Can Aletta® perform a venipuncture in either the left or right arm?

Yes. Aletta can perform a venipuncture in either arm.

Can Aletta® collect multiple blood tubes during one blood draw?

Yes. Aletta can automatically collect and handle up to ten blood collection tubes during a single procedure based on your laboratory orders.
