AI-powered blood test detects liver cancer across distinct populations

Researchers at the Johns Hopkins Kimmel Cancer Center validated an artificial intelligence (AI)-powered blood test that accurately detected liver cancer in people from two geographically and biologically distinct populations and also uncovered the underlying biological signals that make the test effective.

New home test uses thigh length to detect type 2 diabetes or prediabetes

A new home test can detect type 2 diabetes or prediabetes with high accuracy. The test has been developed using artificial intelligence and large amounts of health data – and surprisingly, one of the steps involves measuring the length of your thigh.

New blood test could save millions through early tuberculosis detection

A new study presented today at ADLM 2026 in Anaheim, California found that a simple blood test could accurately identify tuberculosis (TB) - a leading cause of death worldwide - among patients with varying degrees of exposure to the disease.

Blood tests improve Alzheimer's detection in Down syndrome patients

New blood tests that detect early changes associated with Alzheimer's disease are making diagnosis easier and accessible to more patients, since they are less invasive than the brain scans or spinal taps typically used for a definitive diagnosis.

Chemotherapy leaves early genomic fingerprints in childhood tumors

Nearly half of childhood tumors treated with common types of chemotherapy showed detectable DNA changes linked to treatment within 18 months, according to a new international study led by The Hospital for Sick Children (SickKids).

Handheld breathalyzer enables precise monitoring of fat metabolism

Researchers from ETH Zurich have developed a portable measuring device that detects the metabolic marker acetone in breath almost as accurately as a mass spectrometer.

New ctDNA blood test improves personalized prostate cancer treatment

A noninvasive DNA blood test can identify metastatic castration-resistant prostate cancer (mCRPC) patients who are most likely to benefit from 223Ra radiopharmaceutical therapy and monitor their progress throughout treatment, according to new research published in the July issue of The Journal of Nuclear Medicine.

Study sheds light on the prognostic value of blood test for predicting cognitive impairment risk

A blood test for the biomarker phosphorylated tau 217 (p-tau217) recently received federal clearance, but questions have emerged around the extent to which such tests can accurately predict whether a cognitively healthy individual will go on to develop cognitive impairment-a key symptom of Alzheimer's disease.

Ultrasensitive biosensor detects early-stage liver fibrosis using small amount of blood

A research team led by Professor Jinsung Park of the Department of Biomechatronic Engineering at Sungkyunkwan University(SKKU), working jointly with Professor Pil-Soo Sung of the College of Medicine at the Catholic University of Korea and Professor Si-Hyun Bae, President of Eunpyeong St. Mary's Hospital, has developed an ultrasensitive electrochemical biosensor capable of accurately detecting "early-stage liver fibrosis"—a condition in which the liver progressively hardens—using only a small amount of blood.

Beckman Coulter Diagnostics expands Alzheimer’s portfolio with CE-marked p-Tau217 blood test and new high-specificity research assay

Beckman Coulter Diagnostics, a global leader in clinical diagnostics and a Danaher company, today announced it received CE Mark under IVDR for its Access p-Tau217 assay, a blood test designed to support clinical evaluation of amyloid pathology in patients with signs and symptoms of cognitive decline.

Blood hormone signature could transform endometriosis diagnosis

People with endometriosis have a distinct pattern of hormones which could be identified by a blood test, with the potential to revolutionise diagnosis of the condition, research suggests.

Advancing Motor Neuron Disease Diagnosis with Non-Invasive Ultrasound and AI

Research led by Professor Hodson-Tole combines ultrasound and AI to improve motor neuron disease diagnosis, reducing reliance on invasive procedures.

Blood test may predict which colorectal cancer patients benefit from chemotherapy

A blood test may help identify which patients with colorectal cancer that has spread to the liver are most likely to benefit from chemotherapy after surgery, according to research presented today at the ESMO Gastrointestinal Cancers Congress 2026.

Alzheimer’s disease biomarkers predict rapid cognitive decline in very old adults

Cognitive decline in very old adults has been considered for decades to be an almost inevitable consequence of aging.

Blood biomarker may predict Alzheimer's progression differently in men

A blood test does not lie, exactly. It reports a number. The question raised by a new mini-review in Brain Medicine, which gathers and weighs a decade of scattered findings, is whether clinicians have been reading the same number in two different ways without realizing it.

Highly-sensitive blood test detects hidden traces of pancreatic cancer

Northwestern Medicine scientists have demonstrated that a highly sensitive blood test can detect traces of pancreatic cancer missed by standard testing, potentially helping physicians identify patients whose disease is more likely to return even when scans appear reassuring.

Simple blood test could identify the most effective obesity drug

Fasting blood tests measuring GLP-1 and GIP levels may predict obesity treatment response to semaglutide and tirzepatide, enhancing personalized therapy.

Scientists find a universal gut microbiome pattern linked to colorectal cancer

Researchers analyzed 6,779 stool microbiome profiles and 906 tissue samples to identify a colorectal cancer microbial signature that remained consistent across age groups, populations, and sequencing methods. The signature aligned with tumor-resident microbes, showed weaker detection for adenomas, and was inversely associated with dietary fiber intake.

Maternal blood test reveals prenatal methylation clues linked to autism risk

Researchers found that maternal plasma cell-free DNA methylation patterns in late pregnancy were associated with later autism diagnosis and maternal obesity in a high-likelihood ASD cohort. The findings suggest cfDNA may offer a minimally invasive way to study prenatal epigenetic changes linked to neurodevelopmental risk, but larger validation studies are needed.
