الهيموغلوبين Hemoglobin HB

HB

🎯الغاية من التحليل:
➖تقييم حالة فقر الدم (anemia)،
فقدان الدم (blood loss) ،
➖الجفــاف (hydration )، و
➖زيادة نسبةالكريات الحمراء (polycythemic condition)
➖تقييم مدى الاستجابة للمعالجة ومراقبة تحسن حالة المريض

Why Get Tested:

To evaluate the hemoglobin content of your blood as part of a general health checkup;

To screen for and help diagnose conditions that affect red blood cells (RBCs);

If you have anemia (low hemoglobin) or polycythemia (high hemoglobin), to assess the severity of these conditions and to monitor response to treatment

هو بروتين دموي حامل للأكسجين يتألف من بروتين اسمه الغلوبين و مرتبط بالـ هيم (heme) التي تحوي على الحديد .
كل كرية حمراء تحوي على ما يعادل 300 مليون جزيء من الخضاب💮طريقــة القياس: –

🔵العوامل التي تؤثر على نتيجة التحليل

➖تحلل الدم Hemolysis
➖العينات الدهنية Lipemic ترفع من قيمة الــHb بشكل كاذب
➖ارتفاع الّــWBC أعلى من 30.000 /مم يرفع بشكل كاذب من قيمة الــHb
➖الاستحمام يرفع من قيمة الــHb بشكل مؤقت
➖السكن في المرتفعات العالية يرفع من نسبة الــHb

⬇⬇Low hemoglobin with low RBC count and low hematocrit indicates anemia. Some causes include:

Excessive loss of blood from, for example, severe trauma or chronic bleeding from sites such as the digestive tract (e.g., ulcers, polyps, colon cancer), the bladder or uterus (in women, heavy menstrual bleeding, for example)

Nutritional deficiencies such as iron, folate or B12 deficiency

Damage to the bone marrow from, for example, a toxin, radiation or chemotherapy, infection or drugs

Bone marrow disorders such as aplastic anemia, myelodysplastic syndrome, or cancers such as leukemia, lymphoma, multiple myeloma, or other cancers that spread to the marrow

Kidney failure–severe and chronic kidney diseases lead to decreased production of erythropoietin, a hormone produced by the kidneys that stimulates RBC production by the bone marrow.

Chronic inflammatory diseases or conditions

Decreased hemoglobin production (e.g., thalassemia)

Excessive destruction of red blood cells, for example, hemolytic anemia caused by autoimmunity or defects in the red blood cell itself; the defects could be hemoglobinopathy (e.g., sickle cell anemia), abnormalities in the RBC membrane (e.g., hereditary spherocytosis) or RBC enzyme (e.g., G6PD deficiency).

⬆⬆High hemoglobin with a high RBC count and high hematocrit indicates polycythemia. Some causes include:

Lung (pulmonary) disease–if someone is unable to breathe in and absorb sufficient oxygen, the body tries to compensate by producing more red blood cells.

Congenital heart disease–in some forms, there is an abnormal connection between the two sides of the heart, leading to reduced oxygen levels in the blood. The body tries to compensate by producing more red blood cells.

Kidney tumors that produce excess erythropoietin

Smoking–heavy smokers have higher hemoglobin levels than nonsmokers.

Genetic causes (altered oxygen sensing, abnormality in hemoglobin oxygen release)

Living at high altitudes (a compensation for decreased oxygen in the air)

Dehydration–as the volume of fluid in the blood drops, the hemoglobin artificially rises.

Polycythemia vera–a rare disease in which the body produces excess RBCs inappropriately
