Values below 60 mL/min/1.73 m² may indicate chronic kidney disease, while values below 15 mL/min/1.73 m² suggest kidney failure. It's important to consider that eGFR can be influenced by factors such as age, sex, and body size. Always consult a healthcare professional for interpretation specific to individual circumstances.

GFR on a blood test stands for Glomerular Filtration Rate. This test is used to used to test how well the kidneys are working. It estimates how much blood passes through the filters in the kidney, called the glomeruli, every minute.

The normal value for GFR is 130-140 ml /min of creatinine(a substance used to check kidney functioning)

The red dot tube is a type of sight or scope with adjustable magnification.

How does a laboratory test get reported as a panel?

A laboratory test is reported as a panel when multiple related tests are grouped together to assess a specific condition or health aspect. This approach allows for a comprehensive evaluation by measuring various biomarkers or parameters simultaneously, often providing a more complete clinical picture. Panels are typically standardized, making it easier for healthcare providers to interpret results and make informed decisions. They can include tests for various diseases, organ functions, or metabolic processes, depending on the panel's purpose.

What does the rdw sd and rdw cv?

Well to all the people who are interested:

These are hematological parameters that indicate an underlying anemic condition.

The normal RBC is spherical and biconcave with a diameter of 6-8 micrometer. any variation in size is termed as anisocytosis and in shape is termed as poilikocytosis. These variations are seen in anemic conditions like iron or folate or Vitamin B12 deficiency or others.

Earlier when blood samples were analyzed manually under microscope the terms aniso and poikilocytosis were used, when such variations were observed, but with the advent of computerized automated blood analysis methods newer terms like RDW, RDW-SD, RDW-CV have come into place, these terms also indicate unusual variations in the size and shape of RBC which are highly indicative of a possible Anemic conditions.

RDW stands for Red Cell Distribution Width

RDW- SD stands for Standard Deviation in RDW

RDW-CV stands for Coefficient Variation of RDW

These are technical terms used in computer interpretation of the given blood samples

If your reports show abnormal values do consult your physician .
