There is no universal parasite test. Diagnosis may use stool studies, antigen or PCR tests, blood smears, serology, imaging or tissue examination depending on the suspected organism.

Evidence-based articles on health, disease, diagnosis, treatment, prevention, and medical questions.
Parasitic infections require organism-specific thinking. Symptoms are often nonspecific, and testing and treatment depend on exposure, geography and the suspected parasite.
In the late 18th century, a remarkable British scholar and physician named George Staunton embarked on an…
Near-infrared light can penetrate scalp and skull, but fNIRS does not prove that ordinary sunlight delivers a therapeutic dose to the brain. Here is what penetration and photobiomodulation studies actually show.
Edema is swelling caused by excess fluid in the tissues; it is not a general explanation for…
Manual diaphragm therapy may change mobility or discomfort in some people, but many systemic claims in the original article were hypotheses, not established physiology. Here is a safer evidence-based version.
ME/CFS is a complex multisystem illness. This evidence summary covers post-exertional malaise, pacing, symptom management and current CDC/NICE guidance.
Ryke Geerd Hamer argued that specific psychological conflicts cause specific diseases and that resolving the conflict drives healing. The hypothesis is testable, but current evidence does not validate his Five Biological Laws.
An evidence summary of kidney replacement therapy in severe acute kidney injury, including timing, intensity and modality. These ICU decisions require nephrology and critical-care teams.
Most cracked heels come from dry thickened skin plus pressure, but diabetes, eczema, psoriasis and other conditions can contribute. Here is how to treat heel fissures safely and when to seek care.
Dry cupping creates suction on intact skin. It may temporarily change local sensation and blood flow, but evidence for meaningful pain relief is uncertain and detox or fat-removal claims are unsupported.
Seven common misconceptions about bipolar disorder, including mania, depression, long-term management and why ordinary mood changes are not the same as a psychiatric diagnosis.
NSAIDs can relieve pain and inflammation but carry real cardiovascular, gastrointestinal and kidney risks. Here is what FDA warnings mean, who should be cautious, and why acetaminophen is different.
Healthy ear canals usually do not need internal cleaning. Learn when earwax needs treatment, why cotton swabs and ear candles can cause harm, and when a blocked ear is not wax.
UV light can change the volatile chemicals released by human skin. An in-vivo study found increased acetaldehyde and propanal after UV exposure, consistent with lipid peroxidation.
Cholesterol is essential to human biology, but apoB-containing particles, especially LDL, have a causal role in atherosclerosis. Dietary cholesterol is only one part of the picture, and lowering LDL reduces cardiovascular events and can produce modest plaque regression.
Fluoride toothpaste reduces tooth decay and is generally safe when used as directed. The main practical concern is repeated swallowing by young children, which can increase fluorosis risk. Claims that ordinary toothpaste routinely causes thyroid or melatonin problems are not established.
Does resveratrol slow aging or explain the French paradox? Human trials show some modest metabolic effects, but no evidence that resveratrol extends human lifespan.
TMD and tinnitus often occur together, but association does not prove the jaw caused the ringing. Learn when somatic tinnitus is plausible and whether treating TMD can help.
Voice can be trained, but the old version of this article mixed useful practice ideas with claims…
