Renal Function Test (RFT)
There are several different tests that can be used to assess renal function. Some common tests include:
Creatinine test: This test measures the level of creatinine in the blood. Creatinine is a waste product that is produced by muscle metabolism and is typically eliminated by the kidneys. Elevated levels of creatinine in the blood may indicate impaired kidney function.
Glomerular filtration rate (GFR) test: The GFR test measures the rate at which the kidneys are able to filter waste products from the blood. This test can be used to estimate the level of kidney function and to detect early stages of kidney disease.
Urine test: A urine test can be used to check for the presence of protein or other substances in the urine that may indicate kidney damage or dysfunction.
Blood pressure test: High blood pressure (hypertension) can be a risk factor for kidney disease. A blood pressure test can be used to check for hypertension and to monitor blood pressure levels in individuals with known kidney disease.
Imaging tests: Imaging tests, such as an ultrasound or CT scan, can be used to visualize the kidneys and check for abnormalities or damage.
Renal function tests are usually ordered by a healthcare provider as part of a routine physical examination or when an individual is experiencing symptoms that may be related to kidney problems, such as fatigue, swelling, or changes in urine output. The results of these tests can help the healthcare provider diagnose and treat any underlying kidney problems, and can also be used to monitor the effectiveness of treatment.
It is important to maintain good kidney health by eating a healthy diet, staying hydrated, and getting regular exercise. If you have a family history of kidney disease or other risk factors for kidney problems, it is especially important to get regular check-ups and follow your healthcare provider's recommendations for maintaining good kidney health.

Rheumatoid Arthritis
Rheumatoid arthritis (RA) is a chronic autoimmune disorder that causes inflammation in the joints and surrounding tissue. It is a symmetrical disorder, meaning it affects the same joints on both sides of the body. The most commonly affected joints are those in the hands, wrists, and feet, although it can also affect the shoulders, elbows, knees, ankles, and hips. RA is a systemic disease, meaning it can affect multiple organs and systems in the body. It is characterized by the presence of inflammation and swelling in the joints, which can lead to joint damage, deformity, and disability. RA is also associated with an increased risk of other health problems, such as cardiovascular disease, lung disease, and osteoporosis. The exact cause of RA is not fully understood, but it is thought to be a combination of genetic and environmental factors. People with a family history of RA are more likely to develop the condition, and certain genetic markers have been identified that may i...
Thrombocytopenia (Low platelet count)
Thrombocytopenia is a condition characterized by a low platelet count in the blood. Platelets, also known as thrombocytes, are small cells that play a crucial role in the blood clotting process. They are produced in the bone marrow and released into the bloodstream, where they help to stop bleeding by forming clots at the site of an injury. There are several potential causes of thrombocytopenia, including: Decreased production of platelets: This can be due to various factors, such as bone marrow disorders, vitamin B12 or folic acid deficiency, and certain medications that affect platelet production. Increased destruction of platelets: Platelets can be destroyed by the immune system in autoimmune diseases, or by certain medications that can cause platelet destruction or dysfunction. Increased platelet consumption: In some cases, increased platelet consumption can lead to thrombocytopenia. This can occur in conditions such as disseminated intravascular coagulation (DIC), a co...
Sick Building Syndrome: The Workplace Epidemic:The Silent Killer in Your Office
Have you ever felt sick while at work or in a public building? You may have experienced Sick Building Syndrome (SBS), a condition that can affect anyone who spends time in an enclosed space. In this article, we'll discuss the causes, symptoms, and prevention of SBS. What is Sick Building Syndrome? Sick Building Syndrome is a condition that occurs when people experience negative health effects due to spending time in a building or enclosed space. The symptoms of SBS can vary, but they often include headache, dizziness, fatigue, nausea, and irritation of the eyes, nose, and throat. SBS can affect people who work in office buildings, schools, hospitals, and other indoor spaces. Causes of Sick Building Syndrome There are many possible causes of Sick Building Syndrome, but some of the most common include poor indoor air quality, inadequate ventilation, and the presence of toxic chemicals or other pollutants in the building. Other factors that can contribute to SBS include high h...
