Mostly false and dangerously oversimplified. An abnormal blood-test value is usually a clue, not a diagnosis. Doctors interpret it using the degree of abnormality, symptoms, medications, hydration, fasting status, other lab values, and whether it persists on repeat testing.
Examples:
* High WBC: can occur with infection, but also inflammation, allergies, steroids, physical stress, tissue injury, smoking, or blood disorders. Low WBC does not automatically mean an immune disorder.
* Low RBC, hemoglobin, or hematocrit: may suggest anemia, but anemia itself has many possible causes. High values may result from dehydration, altitude, smoking, lung disease, or polycythemia.
* High platelets: commonly occur after infection, inflammation, iron deficiency, surgery, or blood loss—not necessarily a bone-marrow disorder. Low platelets can have many causes and do not automatically establish a bleeding disorder.
* High glucose: one reading does not automatically diagnose diabetes. Diagnosis generally depends on the test used, its level, fasting status, and often confirmation.
* High creatinine: can reflect impaired kidney filtration, but may also be influenced by muscle mass, dehydration, medications, supplements, and recent strenuous exercise. Kidney assessment normally includes eGFR and urine albumin, not creatinine alone.
* AST and ALP: are not specific to the liver. AST can rise from muscle injury or exercise; ALP can come from the liver or bones.
* Bilirubin, albumin, total protein, calcium, sodium, and potassium: each has numerous possible causes. The image’s one-value/one-disease claims are incorrect.
* High CRP: does indicate that inflammation is occurring, but it cannot tell you the cause or location; infection, injury, and many chronic illnesses can raise it.
The image also contains garbled or duplicated lines, such as “BUN tine,” “If your creatinine is,” and “If your sodium is fs high,” which further undermines its reliability.
A better rule is: an abnormal result means “investigate in context,” not “you have this disease.” CBC and metabolic panels are screening tools that help narrow possibilities rather than independently establish most diagnoses.
