The normal range of RBS (Random Blood Sugar) is typically between 70-140 mg/dL.

• Normal range of RBS is 70-140 mg/dL

• RBS levels above 140 mg/dL may indicate hyperglycemia (high blood sugar)

• RBS levels below 70 mg/dL may indicate hypoglycemia (low blood sugar)

Centrifuges are used in medical laboratories to separate substances of different densities in a sample by spinning it at high speeds.

• Centrifuges are used to separate components of blood, such as red blood cells, white blood cells, and plasma.

• They are also used to separate DNA, RNA, and proteins in research laboratories.

• Centrifuges are essential for processing samples in microbiology, hematology, and biochemistry.

• Different types of centrifuges, such as microcentrifuges and ult...read more

There are four main blood groups: A, B, AB, and O.

• There are four main blood groups in the ABO system: A, B, AB, and O

• Each blood group is determined by the presence or absence of specific antigens on the surface of red blood cells

• Blood type O is considered the universal donor, while AB is considered the universal recipient

HIV infection occurs when the virus enters the body and attacks the immune system.

• HIV enters the body through contact with infected bodily fluids, such as blood, semen, vaginal fluids, or breast milk.

• The virus targets CD4 cells, which are a type of white blood cell that plays a crucial role in the immune system.

• HIV replicates inside CD4 cells, eventually leading to their destruction and weakening the immune system.

• As the immune system becomes compromised, the individual becom...read more

EDTA stands for ethylenediaminetetraacetic acid, a chelating agent commonly used in laboratories to prevent blood clotting by binding to calcium ions.

• EDTA is a chelating agent that binds to metal ions, particularly calcium, to prevent blood clotting.

• It is commonly used in blood collection tubes to preserve blood samples for testing.

• In laboratories, EDTA is used in various tests like complete blood count (CBC) and blood typing.

• It is also used in molecular biology techniques to...read more

FBS stands for Fasting Blood Sugar, which is a test to measure the amount of glucose in the blood after fasting for a certain period of time.

• FBS is commonly used to diagnose diabetes and monitor blood sugar levels.

• The test requires the patient to fast for at least 8 hours before blood is drawn.

• Normal FBS levels are typically between 70-100 mg/dL.

• High FBS levels may indicate diabetes or prediabetes.

• Low FBS levels may indicate hypoglycemia.
