Organ-age scores with supporting laboratory measurements.
What’s included in Organ Age Panel
HDL Cholesterol (HDL-C)
The amount of cholesterol carried inside HDL particles in the blood.

A blood chemistry result used to estimate bicarbonate when assessing the body's acid-base balance.
Glucose
The amount of glucose, the body's main circulating sugar and an energy source, in blood.
Fasting
Potassium
An electrolyte needed for normal nerve signals, muscle contraction and heart function.
Sodium
A major electrolyte that helps regulate fluid balance and supports nerve and muscle function.

The combined direct and indirect forms of bilirubin, a waste product from red-cell breakdown.
Creatinine
A waste product from normal muscle activity that the kidneys mainly remove from blood.
Cystatin C
A blood marker used to estimate how well the kidneys filter blood.
Estimated Glomerular Filtration Rate (eGFR)Calc
An estimate of kidney filtration calculated from blood markers such as creatinine or cystatin C.
Creatinine-based
Estimated Glomerular Filtration Rate (eGFR)Calc
An estimate of kidney filtration calculated from blood markers such as creatinine or cystatin C.
Cystatin C-based
BUN/Creatinine RatioCalc
A calculated comparison of blood urea nitrogen with creatinine from the same collection.
Blood Urea Nitrogen (BUN)
Nitrogen from urea in blood, a waste product formed when the body breaks down protein.

White blood cells involved in allergic reactions and inflammatory signaling.
Percentage
Basophils
White blood cells involved in allergic reactions and inflammatory signaling.
Absolute count
Eosinophils
A type of white blood cell, reported as a count or percentage of white cells.
Percentage
Eosinophils
A type of white blood cell, reported as a count or percentage of white cells.
Absolute count
Red Cell Distribution Width (RDW)
How much red blood cells vary in size, rather than their average size.
Hematocrit (Hct)
The share of your blood volume occupied by red blood cells.
Hemoglobin (Hgb)
The iron-containing protein in red blood cells that carries oxygen around the body.
Lymphocytes
A group of white blood cells involved in the body's immune responses.
Percentage
Lymphocytes
A group of white blood cells involved in the body's immune responses.
Absolute count
Mean Corpuscular Hemoglobin (MCH)Calc
Calculated average amount of hemoglobin, the oxygen-carrying protein, in each red blood cell.
Mean Corpuscular Hemoglobin Concentration (MCHC)Calc
The calculated average concentration of hemoglobin within packed red blood cells.
Mean Corpuscular Volume (MCV)
The average size of your red blood cells, reported as their volume.
Monocytes
White blood cells that help remove damaged cells and microbes and can develop into tissue immune cells.
Percentage
Monocytes
White blood cells that help remove damaged cells and microbes and can develop into tissue immune cells.
Absolute count
Neutrophils
White blood cells that play a central role in the body's early immune responses.
Percentage
Neutrophils
White blood cells that play a central role in the body's early immune responses.
Absolute count
Mean Platelet Volume (MPV)
The average size of circulating platelets, distinct from how many platelets are present.
Platelet Count
The number of platelets in a given volume of circulating blood.
Red Blood Cell Count (RBC)
The number of mature red blood cells in a given volume of blood.
White Blood Cell Count (WBC)
The total number of white blood cells in a given volume of blood.
Albumin/Globulin Ratio (A/G)Calc
A calculated comparison of albumin with globulins, two groups of proteins in the blood.
Albumin
A liver-made blood protein that helps retain fluid and transport other substances.
GlobulinCalc
Calculated amount of non-albumin blood proteins, found by subtracting albumin from total protein.
Total Protein
The combined concentration of albumin and globulins, the main groups of blood proteins.

Reviews
What people praise
Detailed results with useful explanations
Members appreciate the breadth of lab testing and explanations of what the numbers mean, helping them identify questions or changes they want to discuss further.
Past results in one place
Reviewers value combining earlier lab work with new results, making it easier to see trends and ask questions without searching through separate reports or accounts.
Guidance to revisit between tests
Members appreciate personalized explanations and reminders in the app, giving them a place to ask questions and prepare for conversations with their own doctor between testing rounds.
What people complain about
Getting help with a specific question
Some members describe unanswered requests when they need clarification about a result, an included test or a charge, making the promised support feel less accessible than expected.
Automated help can feel limiting
Some reviewers find the automated guidance repetitive or difficult to navigate, especially when they need to explain a changing situation or reach a person about a specific problem.
Billing disputes take persistence
Customers describe difficulty resolving a disputed charge or obtaining a clear cancellation response, sometimes turning to their card provider after repeated messages fail to settle the issue.
Stories
Danielle H.
Finding a thyroid issue behind familiar symptoms
At 41, Danielle thought her palpitations, concentration problems and poor recovery might be perimenopause. Superpower bloodwork led to follow-up for Hashimoto’s disease and hypothyroidism; she reported that treatment resolved her symptoms and helped her feel like herself again.
superpower.comKoby C.
Taking the next step on persistent high LDL
Koby had struggled to bring down LDL cholesterol despite diet and exercise, with early heart attacks in his family. A Superpower panel prompted him to pursue medication, and he reported a large drop in his lipid results without side effects.
superpower.comRaquel S.
Connecting fatigue and thinning hair with low ferritin
Raquel had accepted constant tiredness as part of raising two young children. After a suggestion to investigate her thinning hair, Superpower testing revealed low ferritin; she reported better energy and new hair growth after starting supplements.
