What does a low WBC means?

A low white blood cell count (WBC) can indicate a weakened immune system, which may be caused by conditions like infections, autoimmune disorders, bone marrow disorders, or certain medications. It can make it harder for the body to fight off infections and illnesses. Consulting a healthcare provider is important to determine the underlying cause and appropriate treatment.

Is WBC 4.6-10.2 an abnormality?

A white blood cell count (WBC) of 4.6-10.2 falls within the normal range, although values can slightly vary depending on the laboratory's reference ranges. If there are concerns about specific symptoms or other abnormalities, it's best to consult a healthcare provider for a comprehensive evaluation.

At what intervals is blood blotted during a bleed time test?

Blood is blotted at 30-second intervals during a bleed time test to assess how quickly the blood stops clotting. This helps to evaluate the function of platelets and clotting factors in the blood.

What does mcv on cbc being low mean?

A low mean corpuscular volume (MCV) on a complete blood count (CBC) typically indicates smaller-than-normal red blood cells. This can be seen in conditions such as iron deficiency anemia, thalassemia, or chronic diseases. Further evaluation by a healthcare provider may be necessary to determine the underlying cause.

Is it rare for 3 of 5 kids to have o positive blood type and other 2 kids have a positive blood type with same parents?

No, it is not rare for 3 out of 5 kids to have O positive blood type while the other 2 have A positive blood type. Each parent passes on one blood type allele to their child, so it is possible for variations in blood type within siblings to occur based on the combination of alleles each child inherits.

What causes neutrophilia and lymphocytopenia?

Neutrophilia (elevated neutrophil count) can be caused by bacterial infections, inflammation, stress, or certain medications. Lymphocytopenia (low lymphocyte count) can result from viral infections, autoimmune disorders, chemotherapy, radiation therapy, or prolonged stress. Both conditions may also occur in response to certain medical conditions or diseases.

How does a blood serum enzyme test diagnose myopathy?

A blood serum enzyme test can diagnose myopathy by measuring the levels of enzymes that leak into the bloodstream when muscle cells are damaged. Elevated levels of enzymes such as creatine kinase (CK) can indicate muscle damage, which is common in myopathy. By analyzing these enzyme levels, healthcare providers can assess the severity of muscle damage and monitor response to treatment.

What does low gobulin mean?

Low globulin levels can indicate conditions such as liver or kidney disease, malnutrition, or autoimmune disorders. Globulins are proteins that help support the immune system and regulate blood viscosity, so low levels may compromise immune function and overall health. It is important to consult a healthcare provider for proper diagnosis and management if low globulin levels are detected.

Father Homozygous: 100% chance of O+

Father Heterozygous: 50% O+ 50% O-

What happens if you don't heat fix a smear prior to staining of a bacterial slide?

If a bacterial smear is not heat fixed prior to staining, the bacteria may not adhere well to the slide and can wash away during the staining process. Heat fixing helps to kill the bacteria, firmly attach them to the slide, and improve the uptake of stain, resulting in better staining results. Without heat fixing, the bacteria may not stain properly or may not be visible at all under the microscope.

Why is MCV high?

A high mean corpuscular volume (MCV) can be caused by conditions such as vitamin B12 deficiency, folate deficiency, liver disease, or certain types of anemia, such as macrocytic anemia. It can also be elevated due to alcohol abuse, hypothyroidism, or medication side effects. Further evaluation is needed to determine the exact cause.
