Tiny, personal blood testing laboratory gets under your skin

Tiny, personal blood testing laboratory gets under your skin | Longevity science | Scoop.it

Blood tests usually involve drawing some blood out of the body. Now scientists from the Ecole Polytechnique Fédérale de Lausanne (EPFL) have developed an implant that allows blood to be analyzed from within the body, with results then transmitted wirelessly to a computer.

 

While still at the experimental stage, the device could make it easier for health care providers to monitor the chronically ill and provide more personalized treatment to cancer patients.

Veebot’s Needle Wielding Robot to Automate Blood Draws

Veebot’s Needle Wielding Robot to Automate Blood Draws | Longevity science | Scoop.it

Taking blood is a fine art. Even the most experienced practioner may require more than one stab to find a vein—seems only natural to wonder, might a robot do the job better? Mountain View’s Veebot thinks so. Veebot wants to take the art out of needlework with their robotic venipuncture machine.

Inexpensive card-sized device runs 50 blood tests in seconds

Inexpensive card-sized device runs 50 blood tests in seconds | Longevity science | Scoop.it

Ordinarily, when medical clinicians are conducting blood tests, it’s a somewhat elaborate affair. A full vial of blood must be drawn, individual portions of which are then loaded into large, expensive machines such as mass spectrometers. The results are usually quite accurate, but they’re not instantaneous, and require the services of trained personnel in a well-equipped lab.

Potential for blood test to detect lung cancer in early stages

Potential for blood test to detect lung cancer in early stages | Longevity science | Scoop.it

While the overall lung cancer five-year survival rate in the U.S. is 15 percent, the odds of survival increase significantly with early detection. However, the expense or invasiveness of current screening methods and the lack of symptoms at early stages of the disease means most people aren’t diagnosed until the cancer is well advanced.

 

Findings by researchers at the University of York could pave the way for a simple blood test that would detect the disease even in its early stages.

Rapid point-of-care testing for multiple diseases from a drop of blood | KurzweilAI

Rapid point-of-care testing for multiple diseases from a drop of blood | KurzweilAI | Longevity science | Scoop.it

A diagnostic system using DNA powder and gold nanoparticles being developed by scientists at the University of Toronto’s Institute of Biomaterials and Biomedical Engineering could provide rapid point-of-care diagnosis of the world’s leading infectious diseases in the near future.

 

BBME PhD student Kyryl Zagorovsky has developed a rapid diagnostic biosensor that will allow technicians to test for multiple diseases at the same time with one small sample, and with high accuracy and sensitivity. The biosensor relies upon gold nanoparticles, which change color.

Berkeley develops quick blood test to ID people exposed to ionizing radiation

Berkeley develops quick blood test to ID people exposed to ionizing radiation | Longevity science | Scoop.it

As early treatment is the key to maximizing the odds of surviving a large dose of radiation, sorting out the radiological exposure of the victims is a high priority. Unfortunately, at present no quick medical screen exists to identify people exposed to dangerous levels of radiation. While there are early changes in white cell populations, these also can result from an infection due to an injury or chemical exposure.

 

Medical researchers at the US Lawrence Berkeley National Laboratory have now developed a simple blood test to determine the exposure of a patient to ionizing radiation, that can be carried out in the field with a hand-held analyzer.

Cheap, Paper-Based Blood Test Costs Only Pennies, No Lab Equipment Needed

Cheap, Paper-Based Blood Test Costs Only Pennies, No Lab Equipment Needed | Longevity science | Scoop.it

An inexpensive diagnostic test made from paper has been developed that can assess liver health in only 15 minutes and for only pennies a test.

 

The test uses a single drop of blood from a fingerprick to measure the presence of liver enzymes, and doesn’t require the presence of a laboratory, instrumentation, or syringes. If liver enzymes are present in the blood, wells within the paper will show a color change, which can be color matched to a scale to determine approximate degree of concentration.
