BLOOD UREA , SERUM -CREATIN

Blood urea, also known as blood urea nitrogen (BUN), is a clinical marker used to assess the concentration of urea nitrogen in the blood. Urea is a waste product formed in the liver as a result of the breakdown of proteins. It is then filtered by the kidneys and excreted from the body through urine.

Blood urea levels are often measured as part of routine blood tests to evaluate kidney function and overall metabolic health. Elevated blood urea levels may indicate impaired kidney function, dehydration, certain medications, or other medical conditions affecting protein metabolism.

While blood urea levels provide valuable information, they are typically interpreted in conjunction with other kidney function tests and clinical assessments to gain a comprehensive understanding of a person's health status. Abnormalities in blood urea levels may require further investigation and medical evaluation. It's important to note that normal reference ranges can vary between laboratories, and interpretation should be done in consultation with a healthcare professional.

Sodium (Na):

• Role: Sodium is a key electrolyte that helps regulate fluid balance, blood pressure, and the transmission of nerve signals.
• Function: It is essential for maintaining the balance of fluids inside and outside cells, and it works in conjunction with potassium to regulate water balance and support nerve and muscle function.
• Sources: Common dietary sources of sodium include table salt (sodium chloride), processed foods, and natural sources like vegetables and dairy products.

Potassium (K):

• Role: Potassium is another important electrolyte that helps regulate fluid balance, nerve signals, and muscle contractions.
• Function: It is crucial for maintaining the electrical potential across cell membranes, which is vital for proper nerve and muscle function. Potassium also plays a role in balancing sodium levels.
• Sources: Good dietary sources of potassium include bananas, oranges, potatoes, leafy green vegetables, and various fruits and vegetables.

Chloride (Cl):

• Role: Chloride is an electrolyte that works closely with sodium and potassium to maintain fluid balance and help in the body's acid-base balance.
• Function: It is a component of stomach acid (hydrochloric acid) and plays a role in digestion. Chloride is also important for maintaining the body's overall electrolyte balance.
• Sources: Common dietary sources of chloride include table salt (sodium chloride), seaweed, tomatoes, lettuce, and celery.
