Getting under your skin for better health
Researchers say interstitial fluid could replace blood to monitor health and wellness
Newswise — The next frontier of continuous health monitoring could be skin deep.
Biomedical engineers at the University of Cincinnati say interstitial fluid, the watery fluid found between and around cells, tissues or organs in the body, could provide an excellent medium for early disease diagnosis or long-term health monitoring.
A prototype of a device that can measure interstitial fluid uses microneedles.
« Getting under your skin for better health
In a paper published in the journal Nature Biomedical Engineering, they outlined the potential advantages and technological challenges of using interstitial fluid.
“Why we see it as a valuable diagnostic fluid is continuous access. With blood, you can’t easily take continuous readings,” said UC doctoral graduate Mark Friedel, co-lead author of the study.
“Can you imagine going about your day with a needle stuck in your vein all day? So we need other tools.”
Researchers are looking for alternatives to monitor a person’s health and wellness. Sweat is a good medium for measuring certain things like stress or anxiety because it contains hormones such as cortisol. But the body is stingy with other chemicals that are not so easily released in sweat, Friedel said.
“Sweat glands are big filters that don’t allow everything to pass through,” he said. “So more than half of the things we want to monitor have no access to sweat at all.”
Blood is the gold standard for health monitoring. But people also have liters of interstitial fluid that make up as much as 15% of their body weight.
“The key feature of blood that makes it so advantageous is we understand blood really well,” Friedel said. “If you have something in your blood, we know what will happen to your heart or your liver,” he said.
Researchers said interstitial fluid contains many of the same chemicals in the same proportions as blood, offering a potential alternative to costly and time-consuming lab work.
The study outlined the various ways doctors can sample interstitial fluid, from applying suction to the skin to deploying microdialysis.
“As biomedical engineers, one of our greatest goals is to help people better manage their health by making diagnostics more accessible,” said co-lead author Ian Thompson at Stanford University.
“A big barrier to this accessibility is that most current diagnostics rely on blood sampling, which can be painful and requires trained personnel to perform. Thus, in recent years there has been growing interest in using interstitial fluid just under the skin as a diagnostic sample that is more accessible and less painful to extract.”
In UC College of Engineering and Applied Science professor Jason Heikenfeld’s Novel Devices Lab, students are developing sensors to measure hormones and other chemicals in interstitial fluid. They use microneedles less than 1 millimeter in length that pierce the skin through a tiny patch.
“If you had a splinter, it probably went deeper into your skin than our microneedles,” Friedel said. “They’re generally painless. I don’t feel it most of the time. The most uncomfortable part is removing the tape that holds the device down.”
But even if you don’t know it’s there, your body does, Friedel said. And this minute reaction can affect the test results.
“There’s a Schrödinger’s observer effect with interstitial fluid. Any time you try to collect and measure it, you inherently change the fluid itself,” Friedel said. “If you stick a needle in your skin, your body becomes inflamed and then your [sample] levels change. For continuous biomonitoring, we want to know those concentrations as they are when you’re not being poked with a tiny needle.
“That’s why it’s such a challenging fluid that hasn’t been used outside of diabetes monitoring.”
Still, researchers say, interstitial fluid holds enormous promise for monitoring health through wearable technology. This could help doctors track the efficacy of drugs to ensure proper dosage or provide early diagnosis of illness by monitoring the immune system.
But Friedel said there is still a lot to learn.
“We’re trying to unlock the box and read the instructions inside to understand what’s in interstitial fluid and what the potentials are for exploiting it,” he said.
Friedel and Thompson worked with co-author Heikenfeld, UC’s James L. Winkle College of Pharmacy, the Sandia National Laboratories in New Mexico and Southeast Missouri State University.
The study was funded through grants from the National Science Foundation, the U.S. Air Force Office of Scientific Research and the U.S. Office of Naval Research.

(Family Features) While many Americans agree Conventional CPR (cardiopulmonary resuscitation) or Hands-Only CPR (HOCPR) significantly improve a person’s chance of survival from cardiac arrest, less than half are confident they can perform either Conventional CPR or HOCPR in an emergency.
Learning CPR
Black or Hispanic adults who experience cardiac arrest outside a hospital setting are substantially less likely to receive lifesaving care from a bystander. In spite of these survey results, the American Heart Association is working to change this by empowering members of these communities to learn lifesaving CPR, and a growing segment of respondents are willing to act in an emergency.
The American Heart Association’s 2023 survey also revealed that as a result of the organization’s efforts to change attitudes about performing CPR, which can lead to lifesaving results, more than half of African Americans said they would be willing to perform CPR in an emergency compared to 37% two years ago. Additionally, Hispanic and Latino respondents are more confident in their abilities to perform CPR.
Committed to turning a nation of bystanders into lifesavers, the American Heart Association’s multiyear initiative, Nation of Lifesavers, helps teens and adults learn how to perform CPR and use an automated external defibrillator (AED); share that knowledge with friends and family; and engage employers, policymakers, philanthropists and others to create support for a nation of lifesavers.
“Each of us has the power in our own hands to respond to a sudden cardiac arrest,” said Anezi Uzendu, M.D., American Heart Association expert volunteer. “We simply need to know what to do and have the confidence to act.”
The long-term goal: to ensure that in the face of a cardiac emergency, anyone, anywhere is prepared and empowered to perform CPR and become a vital link in the chain of survival, aiming to double the survival rate of cardiac arrest victims by 2030. It takes just 90 seconds to learn how to save a life using HOCPR, which can be equally as effective as traditional CPR in the first few minutes of cardiac arrest.
Nationally supported by the Elevance Health Foundation, the American Heart Association’s HOCPR campaign is focused on chest compression-only CPR. If a teen or adult suddenly collapses due to a cardiac event, you can take two steps to save a life: immediately call emergency services and use these tips to begin performing HOCPR.
- Position yourself directly over the victim.
- Put the heel of one hand in the center of the chest and put your other hand on top of the first.
- Push hard and fast in the center of the chest at a rate of 100-120 beats per minute, which is about the same tempo as the song “Stayin’ Alive” by the Bee Gees, and at a depth of approximately 2 inches.
- Continue compressions and use an AED, if available, until emergency help arrives.

How APOL1-mediated kidney disease can impact you, your kidneys and your family
(Family Features) A genetic condition that can cause kidney failure, APOL1-mediated kidney disease (AMKD) represents a group of kidney diseases associated with mutations (changes or variants) in the apolipoprotein L1 (APOL1) genes.
Typically, the APOL1 genes – of which every person has two, one from each parent – create proteins that play a role in immunity. However, some people are born with mutations in one or both genes, and having mutations in both can increase the risk of developing kidney disease and even kidney failure.
In honor of National AMKD Awareness Day on April 30, consider this information from the experts at the American Kidney Fund to better understand the disease and become APOL1 aware.
Understanding Risk Factors
Research shows Black people with kidney disease are more likely to develop kidney failure than any other racial or ethnic group. The reasons for these health disparities include social determinants of health, a higher burden of diabetes and high blood pressure in the Black community, barriers to health care access and genetics.
The APOL1 gene mutations evolved over the past 3,000-10,000 years in people who lived in western and central Africa and are associated with increased protection from a parasite carried by the tse tse fly that causes African sleeping sickness. While protecting from one disease, the mutation – if inherited in both APOL1 genes – is more likely to lead to kidney disease in those of certain African descent, including people who identify as Black, African American, Afro-Caribbean or Latina or Latino.
In fact, an estimated 13% of Black Americans have two APOL1 gene mutations, according to the American Kidney Fund. While not everyone who has two APOL1 mutations will get kidney disease, there is a 1 in 5 chance they will go on to develop AMKD.
Identifying Symptoms
If you have kidney damage, symptoms may not occur until your kidneys are close to failing. As kidney damage worsens, one or more of these symptoms may occur:
- Protein in urine
- Swelling in legs or weight gain
- Feeling weak or tired
- High blood pressure
Should these symptoms occur and you have a family history of kidney disease, talk to a doctor about getting tested for kidney disease, as testing is the only way to determine kidney function. AMKD can cause damage to parts of the kidney that filter blood or, in some cases, cause cells in the kidneys to die, which can lead to damage and scarring that may eventually lead to kidney failure.
Getting a Diagnosis
The only way to know if you have APOL1 gene mutations is to do genetic testing via a blood or saliva sample. Genetic testing may be considered if you have kidney disease and don’t know the cause or if you’re considering donating a kidney. Testing may also be considered if a family member is a carrier for the mutation. If you have questions about genetic testing, discuss your options with a doctor or ask for a referral to a genetic counselor.
Taking Steps to Prevent Kidney Disease
There are currently no treatments available for AMKD. However, there are steps you can take to protect your kidneys and promote general health. Work with your doctor to create a plan to prevent or delay the progression of kidney disease, which may include:
- Doctor visits to check how your kidneys are working through urine and blood tests
- Checking for and managing diabetes and high blood pressure
- A healthy eating plan, which may involve limiting things like sodium (salt)
- Taking prescription medications as directed
- Being active at least 30 minutes each day of the week
- Quitting smoking or using tobacco
If you have the APOL1 gene mutations, you may be able to take part in clinical trials. Trials could provide an opportunity for researchers to develop and test safe treatments for AMKD. Also speak with family members about having genetic testing done if you have the mutation as they may also have it.
