Platelets are tiny blood cells that help your body form clots to stop bleeding. If you cut yourself, it’s the platelets that rush to the site of the injury and help seal the wound by forming a blood clot.

This test is crucial because having either too many or too few platelets can indicate a range of health issues. 

Low platelet counts (thrombocytopenia) can lead to excessive bleeding and bruising, showing that even minor injuries might cause serious bleeding. 

On the other hand, too many platelets (thrombocytosis) can lead to blood clots in your veins or arteries, which can cause strokes or heart attacks.

Doctors order platelet tests to monitor general health, diagnose diseases, or check the effectiveness of some treatments. It’s commonly performed if you have unexplained bruising or bleeding, are showing signs of an infection, or as part of routine health screenings.

Promyelocytes are immature white blood cells and testing for them is crucial for diagnosing and managing certain blood disorders, especially acute promyelocytic leukemia (APL), a subtype of acute myeloid leukemia (AML). In APL, the bone marrow produces an excessive number of promyelocytes, which can crowd out normal blood cells, leading to serious bleeding and clotting problems.

By identifying and counting promyelocytes in a blood sample or bone marrow biopsy, doctors can confirm a diagnosis of APL. This test is vital because APL requires immediate, specific treatment to prevent life-threatening complications. The presence of promyelocytes can also help monitor the effectiveness of treatment, as decreasing numbers generally indicate a positive response to therapy.

Moreover, since other types of leukemia and blood disorders can also affect white blood cell levels and maturity, distinguishing APL through promyelocyte counts aids in choosing the most effective treatment strategy, enhancing the chances of a successful outcome. Testing for promyelocytes is therefore a key step in the early diagnosis and tailored management of patients suspected of having this aggressive form of leukemia.

The eGFR test, or estimated Glomerular Filtration Rate test, is a crucial laboratory measurement used to assess kidney function. It estimates how well the kidneys are filtering blood and removing waste products. Here's a deeper look into what eGFR signifies and why it is so important:

What is eGFR?

eGFR is calculated from the blood level of creatinine along with other variables such as age, sex, and body size. Creatinine is a waste product produced by muscle metabolism and usually filtered out of the blood by the kidneys.

Why is the eGFR Test Used?

1. Detecting Kidney Disease: eGFR is primarily used to screen for and monitor kidney disease. Healthy kidneys effectively filter blood, but damaged kidneys may not perform as well, leading to a lower eGFR.
2. Monitoring Kidney Disease Progression: For patients already diagnosed with kidney disease, regular eGFR tests help monitor the disease's progression. Changes in eGFR over time can indicate whether the kidney function is stable, improving, or worsening.
3. Guiding Treatment: Kidney function, as measured by eGFR, influences decisions about medication dosages and other treatments. Some drugs are eliminated from the body through the kidneys, and reduced kidney function can affect how drugs are dosed and administered.
4. Evaluating Risk: A low eGFR indicates poor kidney function and can be associated with an increased risk of other complications like cardiovascular disease and high blood pressure.

How is eGFR Calculated?

The eGFR is typically calculated using the creatinine level along with formulas such as the MDRD (Modification of Diet in Renal Disease) study equation or the CKD-EPI (Chronic Kidney Disease Epidemiology Collaboration) equation. These formulas adjust for factors like age, sex, race, and body size to provide a more accurate assessment of kidney function.

Interpretation of eGFR Results

• Normal Range: Generally, a normal eGFR value is above 90 mL/min/1.73m², indicating good kidney function.
• Mild to Moderate Decrease: An eGFR between 60 and 89 might suggest some kidney damage, particularly if other signs of kidney disease are present.
• Moderate to Severe Decrease: An eGFR below 60 may indicate chronic kidney disease.
• Severe Decrease: An eGFR below 30 suggests more serious kidney disease, potentially nearing kidney failure.
• Kidney Failure: An eGFR less than 15 typically indicates kidney failure, necessitating dialysis or transplantation for continued survival.

Regular monitoring of eGFR is essential for patients with known risk factors for kidney disease, such as diabetes and hypertension.

Testosterone is an important sex hormone for both men and women. In men, it is made in the testicles. In women, it is made in small amounts in the ovaries.  

It is important for normal male sexual development. During puberty (in the teen years), testosterone helps boys develop male features like body and facial hair, a deeper voice, and muscle strength. Too much testosterone in men can cause shrinking of the testicles, impotence, an increased risk of heart attack and prostate enlargement with difficulty urinating. Too little can cause fatigue, irritability, depression, erectile dysfunction and reduced muscle mass. 

Combined with oestrogen, testosterone helps with the growth, maintenance, and repair of a woman's reproductive tissues and bone mass. Too much can cause acne, excess hair on the face and body, irregular periods and mood changes. Too little can cause low libido and weight gain. 

The optimal time to take a sample when testing for testosterone is between 7am - 10am.
