Where do I find these numbers?
These 9 values come from a standard blood test your doctor orders during a routine checkup or annual physical. The tests are called a CBC (Complete Blood Count), CMP (Comprehensive Metabolic Panel), and hs-CRP (C-Reactive Protein). Your results may have been emailed to you, mailed to your home, or posted to an online patient portal (like MyChart or Quest MyQuest).
How to enter your results below:
โข Date of Birth โ Your birthday
โข Date of Blood Test โ The date your blood was drawn at the lab
โข Albumin, Creatinine, Glucose โ Found on your CMP (Comprehensive Metabolic Panel) results
โข C-Reactive Protein (CRP) โ Found on your hs-CRP test results. Note: this test is often NOT included in routine bloodwork โ you may need to request it separately or order it through the ULTA Labs link above
โข Lymphocyte %, MCV, RDW, White Blood Cells โ Found on your CBC with Differential results
โข Alkaline Phosphatase โ Found on your CMP results
Simply match each number from your lab report to the corresponding field below. Enter the number exactly as it appears on your results โ the units are already set for you. Don't have bloodwork? Use the ULTA Labs link above to order the required nine tests โ no doctor visit needed.* *State restrictions: Direct-to-consumer lab ordering through ULTA Labs is not available to residents of New York, New Jersey, Rhode Island, or Hawaii due to state laws that require a healthcare provider to order lab tests.
If you live in one of these states, here's what to do:
โ Ask your primary care doctor to order a CBC with Differential, a Comprehensive Metabolic Panel (CMP), and a high-sensitivity C-Reactive Protein (hs-CRP) test at your next visit. These are routine, commonly covered tests.
โก If you don't have a primary care doctor, visit an urgent care clinic or walk-in lab and request these three panels. You can also ask during any annual physical or wellness visit.
โข You can print or screenshot this page to show your doctor exactly which 9 biomarkers you need.
โฃ Once you have your results, return here and enter the values below to calculate your biological age.
