Typically, a diagnosis of alopecia areata can be made based on the pattern of hair loss and the patient's medical history. In some cases, a biopsy is needed to confirm the diagnosis. “When we do a biopsy, we're looking for immune cells around the base of the hair follicle in order to make the diagnosis,” says Dr. King.
Can a Blood Test Detect Alopecia? Yes, a blood test can diagnose alopecia. Your doctor may order several blood works to determine the cause of the hair loss along with a scalp biopsy.

Your doctor scrapes samples from the skin or from a few hairs plucked from the scalp to examine the hair roots under a microscope. This can help determine whether an infection is causing hair loss.
Alopecia areata is an inflammatory, non-scarring hair loss associated with autoimmune conditions. It is more commonly seen with thyroid disorders and vitiligo, but alopecia areata has also been linked to diabetes, psoriasis, rheumatoid arthritis, and systemic lupus erythematosus.
Alopecia areata is an autoimmune disease, where a person's immune system attacks the body, in this case, the hair follicles. When this happens, the person's hair begins to fall out, often in clumps the size and shape of a quarter. The extent of the hair loss varies; in some cases, it is only in a few spots.
Causes of Alopecia Areata
In alopecia areata, the immune system mistakenly attacks hair follicles, causing inflammation. Researchers do not fully understand what causes the immune attack on hair follicles, but they believe that both genetic and environmental (non-genetic) factors play a role.
Alopecia areata is a disease that causes the hair to fall out in small patches. When the immune system attacks the hair follicles, the results are hair loss. Some blood tests used to test for alopecia is the ANA test, Anemia #1 Baseline Blood Test Panel, and the CRP.
The first sign of alopecia areata is often a round or oval bald patch on the scalp.
Dermatologist examining a patient with hair loss
To provide you with the right treatment, it's essential to know what's causing your hair loss. Dermatologists have expertise in diagnosing hair loss and counseling their patients on what may help them regrow their hair.
Though the symptoms of alopecia areata typically do not cause physical pain, many people with the condition say that it causes emotional, or psychological, pain. This type of pain is as serious (and can feel the same) as physical pain and can lead to feelings of sadness, depression and anxiety.
If your daily hair fall is more than the usual 80-100 strands of hair, you might be suffering from stress-related hair loss. If you notice bald patches on your scalp, it may be a sign of Alopecia Areata. If you have had the urge to pull out your hair, it may be stress-induced Trichotillomania.
One of the early symptoms of alopecia could be changes to your nail beds. If you notice pitting, small craters, or white patches on your nails, this could be a warning sign.
Baricitinib helps regrow hair by preventing the body's immune system from attacking hair follicles.
It cannot be cured; however, it's possible to regrow hair. For some people, regrowth will happen without any help. Because alopecia areata cannot be cured, people who have regrowth can have more hair loss later.
It is more commonly seen with thyroid disorders and vitiligo, but alopecia areata has also been linked to diabetes, psoriasis, rheumatoid arthritis, and systemic lupus erythematosus. Indeed, individuals with alopecia areata have an increased risk of developing systemic lupus erythematosus.
Female-pattern baldness is a pattern of hair loss (alopecia) caused by hormones, aging and genetics. Unlike male-pattern baldness, female-pattern baldness is an over-all thinning which maintains the normal hairline.
How Long does Hair Loss Last? In half of patients with alopecia areata, individual episodes of hair loss last less than one year, and hair grows back without treatment. These patients may experience recurrent episodes of hair loss that spontaneously regrow or respond quickly to treatments.
Sometimes one or more bald patches develop a few weeks after the first one. Sometimes the first bald patch is regrowing hair whilst a new bald patch is developing. It can then appear as if small bald patches rotate around different areas of the scalp over time.
Everyone is born with hundreds of thousands of hair on the head. The hair cycle consists of three phases: the growth phase, which is called anagen, the resting phase, which is called catagen, and the shedding phase, which is the telogen phase.
Alopecia is the medical term for hair loss, and it can be caused by genetics, hormonal imbalances, lifestyle factors such as how you wear your hair, medical treatments like radiation or chemotherapy, or even a very stressful event.
Scalp biopsies can be used to make or confirm a diagnosis of alopecia. Scalp biopsy is considered mandatory in all cases of scarring alopecia.
Calcipotriol, a vitamin D analog, has been reported to be topically used in treating alopecia areata with promising results. Combination therapy of vitamin D analogs with corticosteroids might also be used in treating alopecia areata.
Frontal fibrosing alopecia
It can come on suddenly or gradually and affect just your scalp or your whole body. Signs and symptoms of hair loss may include: Gradual thinning on top of head. This is the most common type of hair loss, affecting people as they age.
Alopecia areata is sometimes triggered by viral infections such as influenza that causes excess production of interferons (IFN). IFN- γ is one of the key factors that lead to the collapse of immune privilege.
