Answer · Blood Testing

What happens if my blood work comes back abnormal?

Short answer

An out-of-range result is a reason to look closer, not proof that something is wrong. Your provider first decides whether the value is truly abnormal or a one-off, which often means repeating the test under better conditions. You then review the results together and decide whether the finding can be managed at the clinic or needs a specialist or your primary care doctor.

Does one abnormal result mean something is wrong?

Not necessarily. Reference ranges are built from test results in large groups of healthy people, and MedlinePlus notes that it is common for healthy people to sometimes land outside them. The same source lists everyday reasons a result can drift: what you ate or drank, medicines and supplements, hard exercise before the test, and not following preparation instructions such as fasting.

Exercise is a classic example for men who lift. In a study of healthy men, one hour of weightlifting raised the liver enzymes AST and ALT for at least seven days, enough to look like liver trouble on paper. Larger panels add a statistical wrinkle too: the more markers you run, the more likely one lands just outside its range by chance.

When is a result repeated, and how?

A repeat test is common and is often the most useful next step. MedlinePlus says that if a provider thinks a result may be inaccurate, or a result is inconclusive, you will probably be tested again. Some diagnoses also require it by design: the American Urological Association says low testosterone should be diagnosed only after two total testosterone measurements on separate occasions, both in the early morning.

Result A common reason to repeat first What changes on the repeat
Low testosterone Afternoon draw, poor sleep, recent illness Early-morning, fasting draw on a normal week
Raised ALT or AST Hard training in the days before No heavy lifting for about a week beforehand
High CRP or hs-CRP A recent cold, infection or injury Retest once you have fully recovered
High glucose Not fasting A true overnight fast, water only
Borderline anything Normal day-to-day variation Same lab, same time of day, same preparation

Inflammation markers are a good illustration. MedlinePlus explains that CRP rises with bacterial and viral infections and falls as healing happens, so one high reading during a cold says little about long-term heart risk. When a repeat is needed, your provider tells you what to change and what to keep the same. Our answer on working out before a blood test covers the lifting rule in more detail.

What happens at the review visit?

Your results are reviewed one-on-one with a PA-C or MD, who reads them as a pattern alongside your symptoms, history and medicines. A single flag looks very different depending on what sits next to it: a high hematocrit in a man who snores and wakes unrefreshed points somewhere different from the same number in a man who just returned from a ski week at altitude.

Expect to leave with each out-of-range value explained in plain language and a decision for each one: watch it, retest it, change something, treat it or refer it. Our guide on how to read a men’s health lab report shows how the sections of a report fit together.

When is it treated at the clinic, and when do you see a specialist?

The deciding question is whether the finding falls within the services the clinic provides. Which results stay in the clinic and which go to a specialist is a clinical judgment made at your review, not a fixed rule, but the patterns are fairly consistent.

  • Often managed in the clinic. Confirmed low testosterone, a weight-related rise in blood sugar or triglycerides, and nutrient gaps such as low vitamin D or B12 can lead to a discussion of options on the menu, such as testosterone therapy, medical weight loss or nutrient support.
  • Often referred. A raised PSA usually means a urology evaluation; our page on high PSA before TRT explains why. Persistent abnormal kidney function, unexplained anemia, or a pattern suggesting a thyroid, pituitary or liver condition typically goes to your primary care doctor or the right specialist.
  • Shared. Heart-risk findings like a high Lp(a) or ApoB are often best handled together with your primary care doctor, who can coordinate cholesterol treatment.

When a referral is made, you leave with a copy of the results and a clear explanation of why. Our guide to coordinating care with your primary care doctor covers how that hand-off works.

When is an abnormal result urgent?

Rarely, a lab value is dangerous enough that it needs attention the same day, and labs alert the ordering provider when that happens. Separately from any lab result, symptoms always come first.

Do not wait for a lab review if you have symptoms. Chest pain, shortness of breath, signs of a stroke such as face drooping, arm weakness or slurred speech, or fainting need 911 or the nearest emergency room.

How Ultimate Male handles the next steps

At Ultimate Male, blood is drawn on site the same day at San Gabriel or Downey, results usually come back within 24 to 48 hours, and every panel includes a review with a PA-C or MD. If a repeat is needed, we tell you when and how to prepare. If treatment is appropriate, we explain the options and what monitoring involves. If the finding is outside our scope, we say so plainly and point you to the right next stop.

Our answer on how long blood test results take explains turnaround by test type, and our preventative blood testing page lists the panels. Questions about a report you already have? Bring it to the free 10-minute call at 626-319-5261.

Still unsure? Take the free assessment

Will I be told about an abnormal result before my review visit?
Ask how results are communicated when you have your blood drawn. A result that needs prompt attention should not wait for a routine appointment, and you can always call the clinic if you see something on your report that worries you.
Should I change my diet or supplements before the repeat test?
Only if your provider suggests it. Changing several things at once can make the repeat result harder to interpret, so ask what to keep the same and what to adjust.
Can I get a copy of my results for my own doctor?
Yes. Ask for a copy of the full report, including reference ranges, so your primary care doctor or specialist sees exactly what was measured.
