Bilirubin Linearity Sets

Hey Jerek,
Great to hear from you! I hope pumpkin spice season is treating you well. I think the best next step from here is to hop on a call with one of our product design engineers Nicole Miller so we can go through design, packaging etc and ensure we get all the details right to quote this.
Do you have some time tomorrow afternoon or next week we can connect to dive in? You can book a time that fits your schedule here. Please book a time after 11am EST so my west coast counterpart can attend.
Thank you,
Andrew Hartmann

Subject: Bilirubin Linearity Sets
Hi Andrew,
Has been a long time since we spoke last but wanted to reach out about UTAK manufacturing urine bilirubin linearity sets for us.
Our urinalysis panel has taken off since we discussed this, and I need to get a bilirubin linearity set to market for regular use for our customers.
Required needs:
1. Bilirubin in urine (donor and synthetic options)
2. 5 Levels (mg/dL)
o 0.5
o 1.0
o 5.0
o 10.0
o 30.0
3. Approximate stability (we can do our own testing as well to compare to yours)
a. Frozen
b. Time after thawing
4. 1 mL volume per set
I have attached out previous email chain from late 2024.
If the linearity sets looks good on our end, then we would like to try having UTAK make our calibrators and controls as well.
Thanks,
