Do you know who can donate blood to you or who can you donate blood to? Blood donation may not be complex, but it does need to be compatible with yours and vice-versa. The blood types are determined by the presence or absence of certain antigens - substance that can trigger immune response if they are foreign to the body.

There are four major blood groups which are determined by the presence or absence of two antigens, A and B, on the surface of red blood cells. There is also a protein called the Rh factor, which can either be present (+) or absent (-), which creates A+, A-, B+, B-, O+. O-, AB+, AB- blood types.

Group A blood type has only A antigens on red blood cells and B antibody in the plasma. B has only B antigen on red cells and A antibody in the plasma. AB has both A and antigens on red cells, but neither A nor B antibody is present in the plasma. O has neither A nor B antigens on red cells, but both A and B antibody are present in the plasma.

Blood Type And Who Can You Donate To?

Your blood type determines who can you donate to. This is because there are very specific ways in which blood types must be matched for safe transfusion. The right blood transfusion could actually save you, while the wrong one could be lethal. Also, Rh-negative blood is given to Rh-negative patients and Rh-positive or Rh-negative blood can only be given to Rh-positive patients.

If you are O blood type, you can donate to O, A, B, and AB, if you are A blood type, you can donate to A and AB, if you are B blood type, you can donate to B and AB, however if you are AB, you can only donate to AB.

Who Can You Receive Blood From?

If you are O blood type, you can only receive from O. If you are A, you can receive from type A and O. If you are blood type B, you can receive from type B and O. If you are AB, you are lucky, you can receive blood from O, A, B, and AB.

There are more than 600 other known antigens, the presence or absence of which creates "rare blood types". Certain types are unique to specific ethnic or racial groups, this is why an African-American blood donation can be the best hope for the needs of patients with sickle cell disease, as per the Red Cross Organization.

Universal Blood Donor

Type O is one in high demand, as it can donate blood to anyone. O negative blood type is the universal blood type, which can donate to everyone, especially during the emergency transfusions and for immune deficient infants.

Who Have These Blood Types In US?

In the US, 37% Caucasian, 47% African-American, 39% Asians, and 53% Latino-American are O-positive. However, only 8% of Caucasian, 4% of African-American, 1% Asian, and 4% Latino=Americans are O-negative.

A+: 33% Caucasian, 34% African-American, 27% Asian, 29% Latino-American

A-: 7% Caucasian, 2% African-American, .5% Asian, 2% Latino-American

B+: 9% Caucasian, 18% African-American, 25% Asian, 9% Latino-American

B-: 2% Caucasian, 2% African-American, .4% Asian, 1% Latino-American

AB+:3% Caucasian, 4% African-American, 7% Asian, 2% Latino-American

Continuing the legacy of football legend Joe Thompson, his wife Chantelle revealed she is pregnant with his baby after IVF treatment using frozen embryos.

Joe Thompson died in 2025 after developing cancer for a third time - beating the illness twice.

But after the former Manchester United star was diagnosed with Hodgkin Lymphoma for a third time, which had spread to his lungs, he died aged 36.

"It just means absolutely everything. I know it's never going to replace Joe obviously. Joe's Joe. But to be able to bring his baby into the world again is beautiful," Chantelle said.

She said Joe had two visions of their family with a baby boy before he died, and he even gave her the name for the baby boy he predicted, and she got pregnant on her first attempt of IVF after he had died.

How Egg Freezing Works

Egg freezing, also known as oocyte cryopreservation, is an option that has gained significant traction in recent years. It offers women the ability to pause their biological clock and preserve the possibility of having children in the future.

Egg freezing takes a woman's unfertilized eggs from her ovaries and stores them at sub-zero temperatures to be utilized later. It is made to enable women to keep their fertility intact, especially if they are not yet ready to have a baby.

Dr. Pavithra M, Obstetrician, Gynecologist, and Infertility Specialist, told HealthandMe that the workup begins with hormone workup and evaluation of various parameters, such as age, body mass index (BMI), and ovarian reserve.

"On the second day of the menstrual cycle, baseline ultrasound scanning is performed to assess the number of follicles; thereafter, various tests of blood are conducted to assess hormone levels. If a woman's parameters are all normal, then she is administered hormonal injections for about 10-12 days."

It causes ovarian hyperstimulation and multiple mature eggs, monitored through ultrasound scans. A trigger shot is administered once the follicles have reached optimal size to help with final egg maturation. It takes 34-35 hours from the trigger shot, wherein eggs are retrieved by minimally invasive procedures under general anesthesia.

"Using a transvaginal ultrasound probe with a needle, each follicle is punctured, and the follicular fluid is aspirated. The retrieved eggs are then screened for quality before undergoing vitrification—a rapid freezing technique that minimizes ice crystal formation and cellular damage," Dr. Pavithra added. The eggs are then stored in liquid nitrogen tanks for long-term preservation.

While egg freezing is possible at various stages of life, experts recommend doing it at an optimal age -- in the late 20s or early 30s when the eggs are of higher quality-- for better outcomes.

Annabelle Gurwitch, an American author, actress, and television host, has opened up about her lung cancer diagnosis in her new memoir.

In her sixth book, ‘The End of My Life Is Killing Me’, Annabelle Gurwitch offers a satirical take on her journey with stage 4 lung cancer. The best-selling author found out about her cancer status in 2020, when she went for a COVID-19 test.

In the book, Annabelle Gurwitch writes about her life as a "cancer slacker", her divorce, treatment with a targeted therapy that turns off the gene that has gone rogue, radiation, and chemotherapy, all with a humorous take.

Lung Cancer: A Stealthy Disease, Says Annabelle Gurwitch

Notably, the American actress had no symptoms and was not a smoker. She went to get her “persistent little cough” tested for COVID, when a doctor told her that there was something suspicious on her lungs.

Soon after, an X-ray and a biopsy confirmed her diagnosis of stage 4 cancer.

Annabelle Gurwitch called lung cancer a “stealthy disease" as, other than her little cough, she exercised every day and felt like she was in really good health.

“You know, you can be asymptomatic with Stage 4 lung cancer because lung cancer is a really stealthy disease, and this is why it's such a big killer, still the No. 1 cause of cancer deaths, because some lung cancers, like the one I have, are not recognized by the immune system," Annabelle Gurwitch told NPR.

"So my body didn't know that it was - anything was happening, which is, I mean, I was going to regular doctor's appointments. And this is why it's often diagnosed at a late stage, and such a big killer because it's not diagnosed at an earlier stage,” she added.

Can Non-Smokers Get Lung Cancer?

Contrary to long-held assumptions, a significant proportion of lung cancer cases now occur in people with no history of smoking. The American Cancer Society reports that approximately 10-20 percent of lung cancers in the U.S are found in non-smokers, often attributed to genetic mutations like EGFR, environmental exposures, or radon gas.

These cases are more common in women, younger adults, and individuals of East Asian descent, but they can affect anyone.

Early Signs and Symptoms to Look Out For

Lung cancer symptoms can mimic less serious conditions, which is why they’re often dismissed or misdiagnosed. If you experience the following symptoms persistently, don’t ignore them—regardless of your age or smoking history:

• Chest pain or discomfort
• Unexplained shortness of breath
• Persistent cough or wheezing
• Shoulder, back, or rib pain
• Fatigue or sudden weight loss
• Blood in sputum (though not always present).

A visit to the emergency ward (ER) of a hospital can definitely feel scary, and you want every reason to avoid ending up there as a patient. From broken bones to life-threatening emergencies, it’s a place filled with urgency, uncertainty, and intense emotions. Imagine what doctors and other health workers face every day.

However, while many cases are unavoidable, there are several that can be completely prevented, said doctors, while sharing a few. These include:

• Symptoms ignored for long

However, ignoring symptoms like a persistent stomachache or a nagging cough can allow a condition to worsen over time, eventually leading to an emergency.

“People say, ‘It’s pretty mild. I’m not worried about it,’” Dr. Evelyn Huang, an emergency-room physician with Orlando Health, was quoted as saying to Time.

“Days become weeks, weeks become months, and months can even become years, and by the time they're seeing me, these things have progressed so far that they’re now something dangerous.”

Seeking timely medical advice and not delaying checkups can help prevent complications and avoid unnecessary ER visits, the expert said.

• Drowning

Dr. Cheyenne Falat, assistant medical director of the adult emergency department at University of Maryland Medical Center stated that every time a patient comes ER with a drowning case, he hears the same story.

“I would have been watching them, but I thought the babysitter was watching them. I thought my spouse was watching them. I thought their grandparents were watching them.”

The doctor recommended instead starting swimming lessons as early as possible. She also urged for fences with childproof gates near pools.

• Falling

• Frostbite and hypothermia

People often don’t realize how quickly conditions can turn.

“They think, ‘I won’t be at risk for hypothermia because it's a little warmer during the day,’” said Falat. “Then they sweat,” which can leave their clothing damp and their bodies more vulnerable once temperatures drop.

Heat-related illnesses include mild dehydration to heat exhaustion and, in the most extreme cases, heat stroke, which can be deadly.

• Choking during sex

Recently, for example, he treated a young woman who came to the ER with neck pain, a hoarse voice, and bruising; she assured Yoo that she had wanted her partner to choke her. “I’m not judging anyone who enjoys this, but it's way more dangerous than people think,” he said.

• Party drug

A harmless party drug -- gamma-hydroxybutyric acid, or GHB -- can also turn life-threatening. It is a clear, odorless substance sometimes called “liquid ecstasy.”

While in small amounts, it can make people feel relaxed or euphoric, but when taken in overdose, it can lead to unconscious and breathing difficulties. “It’s one of the most awful sights,” Yoo said , adding that in severe cases, some patients need to be put on a ventilator to survive.
