What Blood Tests Can (and Can't) Tell You About Your Health

Blood tests are powerful but not all-knowing. They can detect many conditions, but they have limits. Here's a quick look at what they can and can't reveal.

What they CAN detectWhat they CANNOT detect
Infections (e.g., bacterial, viral)All cancers (some markers exist, but not definitive)
Anemia, blood disordersNeurological conditions (e.g., Alzheimer's)
Organ function (liver, kidney, thyroid)Autoimmune diseases (often require additional tests)
Cholesterol, blood sugar, heart riskMental health conditions (e.g., depression)
Nutritional deficiencies (iron, vitamin D)Structural issues (e.g., joint damage)

No single blood test checks everything. A comprehensive metabolic panel (CMP) and complete blood count (CBC) are common starting points, but your doctor may order specific tests based on symptoms.

Frequently asked questions

Which is the best diagnostic centre?

The best center depends on your needs. For routine blood work, Quest Diagnostics and LabCorp are both reliable and have multiple Roseville locations. For imaging, Dignity Health Advanced Imaging is a top choice. Compare services, convenience, and insurance acceptance to decide.

Who is bigger, LabCorp or Quest?

Quest Diagnostics is larger in revenue and employee count, but LabCorp is also a major national lab. Both operate extensively in Roseville and offer similar services. Your choice may come down to location and insurance network.

What does 'healthcare diagnostics' mean?

Healthcare diagnostics refers to tests and procedures used to identify diseases or conditions. This includes blood tests, imaging (X-ray, MRI), and other lab analyses that help doctors make treatment decisions.

Is there a blood test that can check for everything?

No single blood test can check for everything. A comprehensive metabolic panel (CMP) and complete blood count (CBC) cover many basics, but specific conditions require targeted tests. Your doctor will order based on symptoms and risk factors.

What illnesses don't show up on a blood test?

Blood tests can't detect all conditions. For example, many cancers, neurological disorders like Alzheimer's, and mental health conditions often require imaging or other evaluations. Blood tests are a tool, not a complete picture.
