What the panel measures
Liver and kidney markers come from one tube and usually arrive as part of a comprehensive metabolic panel. Each number reflects a different job, and several can move for reasons that have nothing to do with disease.
| Marker | What it reflects | Common reasons it shifts without disease |
|---|---|---|
| ALT and AST | Enzymes released when liver cells are stressed; AST also comes from muscle | Hard or unfamiliar weight training |
| ALP | Liver and bile ducts, and also bone | Bone growth or healing |
| GGT | Liver and bile ducts | Regular alcohol, some medicines |
| Bilirubin | How the liver clears a breakdown product of red cells | Gilbert’s syndrome, fasting |
| Albumin and total protein | The liver’s protein production | Hydration |
| Creatinine and eGFR | How well the kidneys filter | Muscle mass, a large meat meal |
| BUN | A waste product filtered by the kidneys | Dehydration, high protein intake |
MedlinePlus explains that an eGFR between 60 and 90 can suggest early kidney disease and one between 15 and 60 may mean kidney disease, and that muscle mass affects the creatinine used to calculate it. Our guides to ALT and AST liver enzymes and the eGFR and creatinine test explain both in more depth.
One detail surprises many men. The American College of Gastroenterology guideline puts a truly healthy ALT at 29 to 33 IU/L for men and says higher levels should be assessed, which is lower than the upper limit printed on many lab reports. Reference ranges differ by laboratory, so your provider reads your number against both.
Reading the pattern, not one number
Providers rarely judge a liver panel on a single value. The ACG guideline describes two broad patterns. When AST and ALT rise much more than ALP, the stress is mainly on liver cells, which points toward causes such as fatty liver, alcohol, medicines, supplements or viral hepatitis. When ALP rises out of proportion, the problem is more likely in the bile ducts, which leads to a different set of tests.
Bilirubin adds another layer, since the guideline notes that a raised conjugated (direct) bilirubin implies liver disease or a blocked bile duct, while the unconjugated form is often benign. On the kidney side, a falling eGFR means more when it is confirmed on a second draw and when the urine shows protein. Context from your medicines, training and drinking habits turns those patterns into a plan.
Why men on testosterone, GLP-1s, supplements or alcohol should check
Testosterone. A baseline before treatment makes any later change easier to interpret. Men weighing oral options can read our answer on whether oral testosterone is bad for the liver.
GLP-1 medicines. The MedlinePlus semaglutide page asks you to tell your doctor about kidney disease before starting, warns that being unable to keep fluids down can cause dehydration, and lists decreased urination among the serious side effects to report right away. Weight loss can also improve a fatty liver, as our answer on semaglutide for fatty liver explains.
Supplement stacks. Some herbal and bodybuilding products have been linked to liver injury, and you cannot tell which from the label. Our answer on whether supplements can damage your liver lists the usual suspects.
Regular alcohol. Drinking shows up in GGT and the liver enzymes, and it is a common driver of fatty liver. Our condition page on fatty liver disease in men covers what helps, and the GGT blood test page explains that marker.
When an abnormal result needs a repeat draw
Many abnormal results are real but temporary. MedlinePlus notes that if you have been ill recently, some abnormal liver results may not last, and your provider may repeat the tests later. Training matters too: in a study of healthy men, one hour of weightlifting raised AST and ALT for at least seven days.
| Situation | Usual next step |
|---|---|
| Mild ALT or AST rise after a hard training week | Repeat after a week or more without heavy lifting; see high liver enzymes after lifting |
| Abnormal results during or just after an illness | Repeat once you have recovered |
| High creatinine in a muscular man | Add cystatin C; see the cystatin C test |
| Isolated high bilirubin with normal enzymes | Often Gilbert’s syndrome; see high bilirubin and Gilbert’s |
| Enzymes still raised on repeat, or very high at first | Further workup, which the ACG guideline says includes checks for viral hepatitis, fatty liver, iron overload and a review of medicines |
Some symptoms cannot wait for a repeat draw. Yellowing of the eyes or skin, severe abdominal pain, confusion or making very little urine needs same-day medical care or an emergency department, not a lab appointment.
How the draw works at Ultimate Male
Liver and kidney function are part of the clinic’s Targeted Preventative Health Panel and are included in the 40+ marker comprehensive panel. Whether they can be ordered as a stand-alone set, and the price, are details to confirm on the free call before booking.
Draws happen on site at San Gabriel and Downey, and results usually come back within 24 to 48 hours. Fast as instructed, skip unusually hard or new lifting for about a week beforehand, drink water normally and bring a list of every medicine and supplement you take. A PA-C or MD reviews the results with you and explains whether anything needs repeating, changing or a closer look.
Paying for liver and kidney testing
Ultimate Male is direct-pay and does not bill insurance. Lab testing and the clinical review are FSA and HSA eligible, with an itemized receipt you can also use for out-of-network claims, and prices are quoted before you book.
