‘I have a blood test coming up — how should I prepare?’: Ask a doctor

It’s common for doctors to recommend getting bloodwork following a medical appointment or routine check-up.

Blood tests can identify deficiencies in vitamins or minerals, immune system problems, or signs of infection, as well as whether organs like the liver, heart or kidneys are functioning correctly, according to the University of Pittsburgh Medical Center.

Fox News Digital spoke with a doctor about how to be prepared for your next blood test.

Reasons for blood tests

Doctors may order blood tests for three main reasons: screening, diagnostics or monitoring.

Screenings are unrelated to symptoms and are based on age, risk factors or the last time you were checked, according to Brintha Vasagar, MD, a family physician with Bayhealth Family Medicine in Dover, Delaware. 

These tests can screen for things like cholesterol, glucose, HIV or hepatitis C.

Tests for diagnosis are based on the symptoms you have communicated to your physician, said Vasagar.

“We carefully choose bloodwork to help rule in or rule out diseases that might be causing those symptoms,” she told Fox News Digital.

Doctors may order blood tests for three main reasons: screening, diagnostics or monitoring. 

Blood tests for monitoring could be performed if you already have a diagnosis and your physician wants to make sure the treatments are working and to check for any negative side effects, Vasagar said. 

These tests will help your physician make recommendations for changing medicines or lifestyle habits.

What to expect from a blood draw

A technician will take you to a private area and confirm your name and date of birth, Vasagar shared.

After seating you in a chair, the technician will place a tight band around your upper arm to help your veins become more accessible. 

Next, the technician will clean the area and insert a small needle to collect vials of blood, the doctor said.

“Some blood tests require different types of testing, which is why we sometimes need several vials of blood,” she said. 

“When they have what they need, they will remove the needle and hold pressure to help your blood clot.”

The technician will label each vial of blood with your identifying information and ask you to verify that it is correct, Vasagar added.

What to do before your blood test

If you have any fear or anxiety about getting blood work, experts recommend discussing your concerns with your health care provider ahead of time. 

“They see many people who are anxious about needles and blood, and they can help you calm down,” noted the University of Pittsburgh Medical Center. 

“Some people like to schedule for first thing in the morning so that their fasting time takes place overnight and is less impactful to their daily routine.”

“I usually prepare patients with what we expect the results to be, and when they can expect to meet with me again or receive a call to discuss results,” said Vasagar.

“I also tell patients that they will always receive communication about those results, even if they are normal, so if they have not heard anything, they should call.”

You can carry on with your normal routine the day before a blood test. However, if your doctor has asked you to fast, you should avoid eating or drinking anything other than plain water for eight to 12 hours before your blood test, said Vasagar.

“Some people like to schedule for first thing in the morning so that their fasting time takes place overnight and is less impactful to their daily routine,” she said.

Fasting is only required for specific blood tests, so it’s important to check with your doctor.

If fasting isn’t required, it’s a good idea to eat and drink before getting your blood drawn to prevent lightheadedness, according to Vasagar. 

“If you start feeling dizzy, tell your technician so they can help you lie down and get you a snack and water,” the doctor said.

More smart planning tips

Blood will be drawn from your arm, so dress in a way that allows the technician to access your arm. 

“Layering is a great way to stay warm while allowing for easy bloodwork,” Vasagar suggested.

Grieving mom hospitalized with rare ‘broken heart syndrome’ after veteran son’s suicide

NEWYou can now listen to Fox News articles!

A distraught mother who thought she was having a heart attack was instead hospitalized with broken heart syndrome — otherwise known as takotsubo syndrome (TTS) — less than a year after her veteran son tragically took his own life.

Dawn Turner, 57, of the U.K., lost her son in August of last year. 

Just last month, the mom of three awoke with “unbearable” chest pains, she said — and called an ambulance, worried she was going into cardiac arrest. But when she arrived at the hospital, doctors told her she was suffering from the effects of grief caused by a broken heart, as news agency SWNS reported.

TTS is a temporary, reversible heart condition often triggered by extreme emotional or physical stress, such as grief, fear or severe illness, according to experts.

Symptoms usually mimic a heart attack, with sudden and severe chest pain and shortness of breath the most common — and it primarily affects women over the age of 50.

Turner, of Eckington in Worcester, said, “I was [sitting] downstairs earlier that night and thought I had a bit of indigestion. I went to bed and just couldn’t get comfortable — I was breaking out in a sweat and had heart palpitations.

“Then, around midnight, I had pain down my arm and in my jaw. I was still putting it down to indigestion… My partner Paul asked me if I was all right, and I said, ‘I think I’m having a heart attack.’”

She said she couldn’t catch her breath — “and my heart felt as though it was missing a beat and then [started] thudding again. For those moments, I truly believed I was having a heart attack.”

“Your heart is all over the place — there’s an extra beat,” Turner was told. 

She said her partner called emergency services, and an ambulance arrived within five minutes.

“They came in and linked me up to an ECG. They said, ‘Your heart is all over the place — there’s an extra beat, and it’s all over the place,’” she said, as SWNS reported.

In emergency care, Turner was also given blood tests.

She added, “They came back and said I didn’t have the enzymes produced from a heart attack in my blood. But they said there [was] something going on.”

After undergoing more tests and seeing a cardiologist, Turner was told she had takotsubo syndrome.

“I told [the doctor] that my heart feels broken. I told her about [my son] Rob, and she said it’s exactly that. She said it’s a real thing, and that I’d been under so much stress. The body can only take so much, and the grief and the stress can be quite physical.”

Turner’s son committed suicide in August 2025 after struggling to get help with his mental health.

He spent 10 years in the Royal Horse Artillery after joining in 2006, when he worked as an artilleryman.

Turner’s son did two tours of duty in Afghanistan, she said. After he returned to civilian life, he began suffering from a number of health conditions. She’s shown above with a flower-draped memorial to her son. (SWNS)

He did two tours of duty in Afghanistan, she said, and returned to civilian life in 2016 before suffering several worsening health conditions.

Turner, who is also the CEO of a veterans charity called Stepway, “When he left the army, he got married, and they settled down in London. He walked straight into a job as a delivery driver. But then his health took a downward spiral, and he started having digestive troubles.”

YOUR HEART MAY BE OLDER THAN YOU THINK — AND THE NUMBER COULD PREDICT DISEASE RISK

He was eventually told he had PTSD — but those symptoms may be similar to those of mild traumatic brain injury, Turner said.

“He was deaf in one ear from using the guns,” she said. “He realized he was putting so much pressure on his marriage, so he moved back up with me. He started to build himself up — then COVID hit.”

Turner said there were unfortunate delays as her son tried to get access to various services and facilities.

“When people lose loved ones, you’re obviously distraught, but you eventually find closure,” she said, per SWNS. “I found peace when I lost my sister in 2015. But with Rob, I can’t find closure because there’s no justice there.”

“I had never really understood that a person could become so overwhelmed by stress and grief that it physically affects the heart,” said the grieving mom. “Broken heart syndrome can look and feel like a heart attack.” (iStock)

Turner is now on the mend and hopes to be fully recovered in a couple of weeks, SWNS reported.

“Until that moment, I had never really understood that a person could become so overwhelmed by stress and grief that it physically affects the heart,” she shared. “Broken heart syndrome can look and feel like a heart attack. It was a warning sign for me, and for anyone. It can change the shape of one of your heart chambers … it can cause some serious damage.”

She added, “The cardiologist told me that thankfully, my heart itself is healthy and there was no damage, but that it will take around two weeks to a month for my heart to reboot itself.”

“Maybe the extra [heart]beat is for Rob. You are carrying on living for him,” her partner told her. 

Turner was told she needed to rest, seek counseling and make lifestyle changes to reduce stress.

“Things have settled down, and I’m taking things easy — I’m pacing myself now, and I feel a lot better. Paul said, ‘Maybe the extra beat is for Rob. You are carrying on living for him.’”

Turner said, “That broke me and healed me a little bit all at once.”

Fox News Digital previously reported that broken heart syndrome, which causes the heart to temporarily weaken, has been linked to the brain’s reaction to stress, as studies have found.

Caused by intense emotional events, TTS is a rare, temporary condition that weakens the left ventricle and disrupts its normal pumping function.

The syndrome causes the heart’s main pumping chamber to change shape and get larger. The heart muscle becomes weaker, and its pumping action loses strength.

Common eating habit may trigger premature immune system aging, study finds

Common eating habit may trigger premature immune system aging, study finds

NEWYou can now listen to Fox News articles!

Eating too much salt has long been linked to high blood pressure, but new research suggests it could trick the immune system into prematurely aging the blood vessels.

A preclinical study recently published in the Journal of the American Heart Association has identified a biological chain reaction that links a salty diet to cardiovascular decay.

Scientists at the University of South Alabama observed that mice on a high-salt diet experienced rapid deterioration in their blood vessel function.

HIGH SALT INTAKE LINKED TO FASTER MEMORY DECLINE IN ONE GROUP, STUDY FINDS

After just four weeks of high sodium intake, the small arteries responsible for regulating blood flow lost their ability to relax, according to a press release.

The team found that the cells lining these vessels had entered a state of cellular senescence, a form of premature cellular aging in which cells stop dividing and release a mix of inflammatory signals that can damage surrounding tissue.

The researchers tried to replicate this damage by exposing blood vessel cells directly to salt in a laboratory dish, but the cells showed no harmful effects.

This suggests that salt isn’t directly causing damage to the vascular lining but that the real culprit may be the body’s own defense mechanism, the researchers noted.

Excess salt may trigger the immune system to release a molecule called interleukin-16 (IL-16), which acts as a messenger that instructs blood vessel cells to grow old before their time, according to the study.

Once these cells age, they fail to produce nitric oxide, the essential gas that tells arteries to dilate and stay flexible.

To test whether this process could be reversed, the team turned to a class of experimental drugs known as senolytics.

Using a cancer medication called navitoclax, which selectively clears out aged and dysfunctional cells, the researchers were able to restore nearly normal blood vessel function in the salt-fed mice, the release stated.

By removing the decaying cells created by the high-salt diet, the drug allowed the remaining healthy tissue to maintain its elasticity and respond correctly to blood flow demands.

The study did have some limitations. The transition from mouse models to human treatment remains a significant hurdle, the team cautioned.

Senolytic drugs like navitoclax are still being studied for safety, and the team emphasized that previous trials have shown mixed results regarding their impact on artery plaque.

Additionally, the researchers have not yet confirmed whether the same IL-16 pathway is the primary driver of vascular aging in humans.
