Laboratory Testing

An increase in white blood cells in a human may indicate an infection, inflammation, or a response to stress or injury. It can also be a sign of certain medical conditions, such as leukemia or lymphoma. Consulting a healthcare provider for further evaluation and testing is recommended in such cases.

Yes, of course you grow,exept if you get a sickness that stops your growth.(growth continues naturally)

The Rh marker can be found on the surface of red blood cells. It is a protein located on the cell membrane that determines whether an individual is Rh positive or Rh negative.

Four components that can be derived from a unit of blood are red blood cells, plasma, platelets, and white blood cells. Each of these components serves different functions and can be used in various medical treatments.

NO. If a person is fasting (no food or drink for 8-10 hours) that is really what the doctor is testing. He/She is trying to get true lab results for lipid profiles, glucose, etc. IF a Complete Blood Count has been included in the laboratory exam, then it is a possiblitiy that the White blood count could be elevated (bacterial infection) or low (Viral infection) because of the fever.

Simple - remove the solution!

Most often the solution is evaporated. The solid will frequently form crystals which are recovered. This is how salt and sugar are manufactured. Sometimes the dissolved substance will decompose if heated. Lowering the pressure lowers the boiling point, so a vacuum evaporator can be used.

omg im sooo clever :P :D

1. The nervous system is divided into two main parts: the central nervous system (CNS) and the peripheral nervous system (PNS).
2. The brain uses about 20% of the body's oxygen and blood supply, despite making up only about 2% of the body's weight.
3. Neurons in the nervous system can transmit signals at speeds of up to 120 meters per second.
4. The average adult human brain contains around 86 billion neurons.
5. The spinal cord acts as a relay station for signals between the brain and the rest of the body.
6. The myelin sheath, made of fatty tissue, helps to speed up the transmission of signals along neurons.
7. The enteric nervous system, often called the "second brain," controls the gastrointestinal system independently of the brain.
8. The nervous system controls involuntary functions like heart rate, breathing, and digestion.
9. Neurotransmitters are chemical messengers that transmit signals between neurons.
10. The nervous system is essential for coordinating all bodily functions and responses to the external environment.

Red blood cells of different groups have different molecules on the surface of their cells these are called antigens. People with blood type A will reject B type blood as they have different antigens on the surface of their cells, these differences are detected by antibodies. Blood type O has none of these antigens and so isn't rejected/detected by the antibodies.

A light blue top tube containing 3.2% sodium citrate is typically used to collect blood for PT/INR testing. The sodium citrate acts as an anticoagulant to prevent blood clotting and ensures accurate results. It is important to follow the exact collection procedures specified by the laboratory to avoid any potential issues with the test results.

A whole uncut strawberry will take longer to spoil compared to a cut strawberry. This is because cutting the strawberry exposes more surface area to air and microbes, accelerating the spoilage process.

A blood test for STDs can help diagnose various sexually transmitted infections such as HIV, syphilis, and hepatitis B and C. The specific diagnosis will depend on the type of infection detected in the blood sample.

A CBC (complete blood count) test is used to measure the levels of different components in the blood, including red blood cells, white blood cells, and platelets. It helps healthcare providers diagnose medical conditions such as anemia, infection, and blood disorders.

The test for proteins is called the Biuret test. This test is based on the principle that proteins react with copper sulfate in an alkaline solution to produce a violet color.

Serous tissues secrete a fluid that lubricates to minimize friction from muscle movement. There are many organs in our body that have serous tissues in it like the heart and the stomach, without the secreted fluid these tissues, these organs will be dry.

Elevated mean corpuscular volume (MCV) levels can be caused by conditions such as vitamin B12 or folate deficiency, alcoholism, hypothyroidism, liver disease, and certain types of anemia like megaloblastic anemia. It is important to consult a healthcare provider for proper evaluation and management if MCV levels are elevated.

Stiffness in a finger with normal inflammatory markers and a weak positive antinuclear antibody (ANA) could indicate a potential autoimmune condition like rheumatoid arthritis or lupus. However, further evaluation by a rheumatologist may be needed to determine the exact cause and develop an appropriate treatment plan.

A blood culture test is used to check for bacterial growth in the blood. During this test, a sample of blood is taken and placed in a culture medium to see if any bacteria present in the blood can grow in the lab. It helps diagnose bacterial infections in the bloodstream.

NEUT in a complete blood count with differential refers to neutrophils, which are a type of white blood cell that plays a key role in the body's immune response to infections. Elevated levels of NEUT can indicate an ongoing infection, inflammation, or stress response.

The nuclear membrane in the human body is similar to the skin, as it acts as a protective barrier that controls the passage of substances in and out of the cell nucleus, much like how the skin acts as a barrier for the rest of the body.

The pores in the nuclear envelope provide a passageway for the movement of molecules such as proteins, RNA, and signaling molecules between the nucleus and the cytoplasm. This allows for communication and coordination between the nucleus and the rest of the cell.

CRISPR technology allows scientists to edit genes and potentially manipulate inherited diseases by altering the DNA sequence. This technology enables targeted changes to specific genes that may be causing genetic disorders. Additionally, gene therapy approaches can introduce healthy genes to replace or correct defective ones in affected individuals.

In a flame test lab, various metal ions are tested by placing a small sample of the compound in a flame, which produces a characteristic color. This color is due to the electrons in the metal ion moving to higher energy levels and then back down to their ground state, emitting light of a specific wavelength. By observing the color produced, one can identify the metal ion present in the compound.

The nucleolus is a structure found inside the nucleus of the cell. It plays a crucial role in the production of ribosomes, which are essential for protein synthesis. In the human body, the nucleolus is present in most cells that actively produce proteins.

You should typically fast for 8-12 hours before having bloodwork done. This allows for accurate measurements of blood sugar, cholesterol, and other factors that can be affected by food intake. Be sure to follow any specific fasting instructions provided by your healthcare provider.
