Laboratory Testing

Neutrophils are a type of white blood cell that plays a crucial role in fighting off infections. By counting the number of neutrophils in a person's blood, doctors can assess the body's immune response and determine if there is an ongoing infection. Abnormal neutrophil levels can indicate various conditions, including bacterial infections, inflammation, or stress on the bone marrow.

Light yellow top tube contains the additive sodium polyanethol sulfonate (SPS) or acid citrate dextrose additives. This tube is used for blood bank studies, human leukocyte antigen (HLA) phenotyping, DNA, and paternity testing.

Squeezing the finger too tightly during a skin puncture may dilute the blood with tissue fluid or interstitial fluid. This can affect the accuracy of the test results by altering the concentration of the analytes being measured.

GFR stands for glomerular filtration rate, which measures how well the kidneys are functioning. Creatinine is a waste product produced by muscles that is filtered out of the blood by the kidneys. Elevated creatinine levels in the blood may indicate decreased kidney function.

"Neuts" in a blood test refers to neutrophils, which are a type of white blood cell that helps the body fight off infections. Neutrophils are a crucial part of the immune system's defense against bacteria and other pathogens. Their levels are often reported as a percentage of the total white blood cell count in a complete blood count (CBC) test.

An MCV (mean corpuscular volume) of up to 99.8 fL (femtoliters) indicates the average size of red blood cells is higher than normal. This can be seen in conditions like macrocytic anemia or liver disease. Further evaluation is needed to determine the underlying cause.

An MCV (mean corpuscular volume) value of up to 99.8 femtoliters typically indicates macrocytic anemia, which is characterized by larger-than-normal red blood cells. This can be due to conditions such as vitamin B12 or folate deficiency, certain medications, or underlying health problems affecting the bone marrow. Further evaluation by a healthcare provider is needed to determine the cause and appropriate treatment.

Without the excretory system, waste products like urea, excess salts, and water would build up in our bodies, leading to toxicity and imbalances that could harm our organs and bodily functions. Ultimately, the lack of an excretory system would be fatal due to the accumulation of harmful substances that our bodies need to eliminate.

Schistocytes are fragmented red blood cells that are commonly seen in conditions such as hemolytic anemia, thrombotic microangiopathy, and disseminated intravascular coagulation. These abnormal cell fragments can be caused by mechanical injury as the blood passes through narrowed vessels or damaged endothelium.

Blood cultures are typically drawn in yellow or gold-top tubes, which contain a special additive that prevents clotting and supports bacterial growth for culture testing. It's essential to follow the specific protocol and use the correct color tube to ensure accurate results and prevent contamination.

It is not necessary to use strict or stringent conditions for all blood tests. Some tests may require specific conditions to yield accurate results, while others can be performed under more flexible conditions without compromising accuracy. The stringency of testing conditions depends on the specific requirements of each test and the analyte being measured.

A low mean platelet volume (MPV) in your blood work could indicate a potential decrease in the size of your platelets. This might suggest a condition like immune thrombocytopenia, where platelet destruction is increased or production is decreased. It's important to follow up with your healthcare provider for further evaluation and management.

Yes, a parent with O positive blood and a parent with A positive blood can have children together. The child could inherit either parent's blood type, resulting in the child having either O positive or A positive blood type.

The Morph blood test, also known as a complete blood count (CBC) with differential, is a common blood test that provides important information about the types and numbers of cells in your blood, including red blood cells, white blood cells, and platelets. It helps to diagnose various conditions such as infections, anemia, and leukemias.

The presence of 14-16 pus cells in the urine may indicate an infection in the urinary tract or in the kidneys. Further evaluation by a healthcare provider is necessary to determine the underlying cause and appropriate treatment.

Having difficulty obtaining enough blood during a blood test could be due to factors such as dehydration, low blood pressure, or difficult veins. It is essential to communicate this issue with the healthcare provider performing the test to ensure accurate results and to determine if further action is needed.

I don't think this can happen...Mom is O; Dad is AB, that gives us the cross:

A B

O AO BO

O AO BO

The child of this pairing would have 50% chance being Type A and 50% Chance being Type B...there's no way for an O to occur since it's a double-recessive...

Yes, a baby can be healthy if both parents are O positive. Blood type compatibility does not impact a baby's health unless there are specific genetic conditions or illnesses present in the parents. Regular prenatal care and genetic testing can help ensure a healthy pregnancy and baby.

A high lymphocyte count in a blood test may indicate an infection, immune system disorder, or a reaction to stress. Further evaluations or tests may be necessary to determine the specific cause.

RBS usually stands for Random Blood Sugar, a test conducted to measure the blood glucose level at any time of the day without fasting. It helps in screening for diabetes, monitoring blood sugar levels in diabetic patients, and assessing overall blood sugar control.

A low TSH result in a blood test typically indicates hyperthyroidism, where the thyroid gland is overactive and producing too much thyroid hormone. This can result in symptoms such as weight loss, anxiety, and rapid heart rate. Further evaluation is needed to determine the underlying cause and appropriate treatment.

A high B12 blood result could indicate several things, such as excessive supplementation, liver disease, kidney failure, or certain cancers. It is important to consult with a healthcare provider to determine the underlying cause and appropriate next steps.

It is typically recommended to fast for 8-12 hours before an EUC (electrolyte, urea, and creatinine) blood test to ensure accurate results. However, you should follow your healthcare provider's specific instructions for fasting before the test.

In laboratory test results, the abbreviation "lymphs" typically refers to lymphocytes, a type of white blood cell involved in the immune response. Elevated or decreased levels of lymphocytes can indicate different medical conditions such as infections, autoimmune diseases, or certain types of cancer.
