Rules for preparing and giving blood for hormones

  1. On the eve of blood collection for ELISA tests (hormones, cancer markers, autoimmune antibodies, etc.) it is necessary to exclude physical activity, stressful situations, physiotherapeutic procedures, taking medications (except in cases of medication prescribed by a doctor, when the decision to cancel medication is made by the attending physician), taking oral contraceptives, drinking alcohol and eating fatty foods. Immediately before the study exclude smoking.
  2. Standard blood sampling is performed in the morning, on an empty stomach (at least 8-12 hours after the last meal), in the treatment room, in the patient's position "sitting" or "lying down", in physiological rest, from the ulnar vein in compliance with the rules of asepsis and antisepsis. Before taking blood, the patient should be given a 15-minute rest.
  3. When examining thyroid function during treatment with drugs containing thyroid hormones, the study should be performed 24 hours after the last intake of the drug. For 2-3 days before blood sampling it is necessary to exclude the intake of drugs containing iodine.
  4. When testing for PSA, one week before the analysis, exclude any manipulations with the prostate gland.
  5. When testing for ACTH, renin/angiotensin, it is recommended to take blood from 7 to 9 am. Reference values of these hormones are designed for this time. The patient should be at rest (sitting or lying down) for at least 1 hour before blood collection.
  6. When testing for cortisol and aldosterone, blood should be drawn before 10am.
  7. When examining sex hormones for women of reproductive age, it is necessary to indicate in the direction the time and date of blood collection, day and phase of the menstrual cycle, in case of pregnancy - indicate the term of pregnancy.
  8. Complex tests (several tests in one sample) are more informative.
  9. All blood tests for hormones for greater reliability and the ability to interpret the results are recommended to be carried out not once, but in dynamics. Repeated studies are carried out at the same time of day after 2-3 weeks. Analysis of the results of studies performed in dynamics is more informative both in diagnostic and prognostic terms.
  10. If the study is conducted during the period of drug treatment, it is necessary to indicate in the referral the name of the drug and the time of the last intake.

MYOSITIS: WHAT PATIENTS NEED TO KNOW

Muscle pain and weakness are symptoms that many people attribute to fatigue or a cold. However, they can sometimes be signs of a serious condition—myositis. Understanding this condition will help you see a doctor in time and start the right treatment.

What is myositis?

Myositis is an inflammation of muscle tissue. The term “myositis” encompasses both common inflammation following overexertion or exposure to cold, as well as serious autoimmune diseases: polymyositis, dermatomyositis, and necrotizing autoimmune myopathy.

In autoimmune forms, the immune system mistakenly attacks the body’s own muscles, causing chronic inflammation. Without treatment, this can lead to persistent weakness, muscle atrophy, and serious complications.

How to recognize myositis: main symptoms

Look for the following signs:

•       Muscle weakness—especially in the shoulders, hips, and neck; difficulty getting up from a chair or raising your arms.

•       Muscle pain—may be constant or worsen with movement and palpation.

•       Increased fatigue—even after minimal physical exertion.

•       Muscle atrophy — with a prolonged course of the disease, muscle mass may decrease, and strength and endurance may decline.

•       In dermatomyositis, characteristic skin rashes may appear: redness around the eyes (the “goggle” sign), and rashes on the finger joints.

•       Possible difficulty swallowing or shortness of breath — if the throat muscles and respiratory muscles are affected (this requires immediate medical attention!).

⚠ Important: If you experience severe shortness of breath, difficulty swallowing, or a sudden worsening of your condition, contact a doctor immediately or call an ambulance.

Why does myositis occur?

The causes can vary:

•       Autoimmune processes—the most common cause of chronic myositis.

•       Viral and infectious diseases—the flu, strep throat, and other infections can trigger muscle inflammation.

•       Injuries and excessive physical exertion.

•       Exposure to cold and prolonged exposure to drafts.

•       Taking certain medications (for example, statins—drugs used to lower cholesterol).

•       Concomitant connective tissue diseases (lupus, scleroderma).

•       Cancer — in some cases, myositis may be the first sign of a tumor.

Treatment and rehabilitation

According to the clinical guidelines of the Ministry of Health of Ukraine, treatment is selected based on the form and cause of myositis. Properly prescribed therapy significantly influences the course of the disease and the prognosis.

Drug treatment

•       Corticosteroids (e.g., prednisolone)—the main treatment for autoimmune myositis, reduce inflammation.

•       Immunosuppressants (methotrexate, azathioprine) — prescribed when corticosteroids are not effective enough.

•       Anti-inflammatory drugs — to relieve pain and swelling.

•       Antibiotics — if myositis is caused by a bacterial infection.

Rehabilitation

Rehabilitation is an integral part of treatment and includes:

•       Physical therapy — a personalized exercise program to restore muscle strength.

•       Physical therapy procedures — to improve blood flow and reduce inflammation.

•       Massage — as a supplement to the main treatment.

Important to remember

•       Do not self-medicate—myositis requires an accurate diagnosis and a doctor’s prescription.

•       Seeking timely medical attention and receiving proper treatment significantly improve the prognosis.

•       Follow rehabilitation recommendations—this will speed up recovery.

•       Avoid triggering factors: hypothermia, excessive physical exertion, and stopping medication on your own.

•       Visit your doctor regularly to monitor your condition and adjust your treatment.

Diagnosis and Rehabilitation at Helios

At the Helios Medical Center, we conduct comprehensive diagnostics, monitor the course of the disease, and develop a personalized treatment and rehabilitation program.

An important part of recovery is properly selected physical rehabilitation and therapeutic exercises, which help maintain muscle strength, reduce the risk of atrophy, and improve the patient’s quality of life.

If you experience muscle weakness, pain, or rapid fatigue, it is important to consult a specialist promptly.
