Blood Work for PEDs

Cortisol is a steroid hormone produced by the adrenal glands, often referred to as the “stress hormone.” It helps regulate a variety of essential functions, including metabolism, blood sugar levels, and the body’s response to stress. During stressful situations, cortisol levels rise to prepare the body for a “fight-or-flight” response.

While short-term increases in cortisol are normal and beneficial in managing stress, chronic high cortisol levels can lead to negative health effects, such as weight gain, anxiety, sleep disturbances, and weakened immunity. Conversely, low cortisol levels can indicate issues like adrenal insufficiency.

Albumin is a protein produced by the liver that helps maintain blood volume and pressure by preventing fluid from leaking out of blood vessels. It also binds various substances in the blood. Low albumin levels can indicate liver or kidney issues, as well as malnutrition. Monitoring albumin is key for detecting potential health problems.

Total Protein measures the combined amount of two key proteins in the blood: Albumin and Globulin.

• Albumin helps prevent fluid from leaking out of the bloodstream, maintaining blood volume and pressure.
• Globulin is produced by the liver and immune system, playing a crucial role in strengthening the immune system by fighting infections and germs.

Platelet count is a medical test that measures the number of platelets in your blood. Platelets are small cells that play a crucial role in blood clotting, helping to prevent excessive bleeding.

A low platelet count can indicate serious health conditions, such as leukemia, cancer, or other disorders affecting bone marrow production or blood clotting. Regular monitoring of platelet levels is important for early detection of potential health issues.

Total Prostate-Specific Antigen (PSA) is a protein produced by the prostate gland in males. PSA levels are measured in nanograms per milliliter (ng/mL) of blood.

• Normal PSA levels are typically below 4 ng/mL.
• PSA levels between 4 and 10 ng/mL may indicate an increased risk of prostate cancer.
• If PSA levels exceed 10 ng/mL, a biopsy is usually recommended to check for cancer.

Higher PSA levels are more common in older men and those who have undergone urologic procedures. Monitoring PSA levels is important for early detection of prostate issues, including cancer.

A Full Blood Count (FBC) test provides key insights into blood health by measuring several components:

• Haemoglobin: Oxygen-carrying capacity of red blood cells.
• Haematocrit: Volume of red blood cells.
• Red Cell Count, MCV, MCH, MCHC: Assess red blood cell quantity, size, and haemoglobin content.
• RDW: Variability in red blood cell size.
• White Cell Count: Total white blood cells, with a differential count to categorize them.
• Platelet Count and MPV: Measures platelets and their size for clotting.

The FBC helps diagnose conditions like anemia, infections, and bleeding disorders.

Haematocrit measures the proportion of red blood cells in the blood. Typically, it is around 40% for men and 38% for women.

• A high haematocrit suggests a higher than normal level of red blood cells, which can be caused by dehydration or other conditions like lung or heart disease.
• A low haematocrit indicates a lower than normal level of red blood cells, which may be a sign of anaemia or other issues like blood loss or nutritional deficiencies.

Testosterone exists in two forms in the blood: bound to proteins and free (unbound). Free testosterone is the active form that does not require transport proteins to function effectively.

When free testosterone levels are low, it can indicate underlying health issues, such as decreased sex drive, anemia, fatigue, or other hormonal imbalances. Low free testosterone can be a sign of conditions like hypogonadism or testicular dysfunction, and addressing these imbalances is important for maintaining overall health.

Sex Hormone Binding Globulin (SHBG) is a protein produced by the liver that binds to sex hormones like testosterone and oestradiol to regulate their circulation in the bloodstream.

SHBG levels are directly related to hormone levels in both males and females. In men, low SHBG levels can indicate low testosterone, while in women, high SHBG levels may signal excess testosterone or estrogen imbalances. Monitoring SHBG helps identify hormonal imbalances and related health conditions.

Globulin is a group of proteins produced by the liver and the immune system. These proteins play a crucial role in immune defense, helping the body fight infections and germs. Additionally, globulins are vital for blood clotting, helping to prevent excessive bleeding following injury. Overall, globulins contribute to maintaining a healthy immune system and proper blood function.

Mean Platelet Volume (MPV) measures the average size of platelets in the blood. Platelets are essential for blood clotting, helping to prevent excessive bleeding from injuries.

Abnormal MPV levels, either high or low, can indicate underlying health issues. A high MPV may suggest an increased production of large, immature platelets, which could be linked to conditions like bone marrow disorders or inflammatory diseases. A low MPV may indicate reduced platelet production, potentially pointing to bone marrow problems or certain bleeding disorders. Both high and low MPV can be harmful and may require further investigation.

The Oestradiol Blood Test measures the levels of oestradiol, a key estrogen hormone in the body. In women aged 50 and above, who are approaching menopause, oestradiol levels typically decrease, leading to various symptoms such as hot flashes, night sweats, mood swings, infertility issues, and osteoporosis.

Low oestradiol levels can significantly impact both physical and mental well-being. A hormonal imbalance can cause discomfort and health challenges, making it important to monitor and address any changes in hormone levels during this life stage.

Prolactin is a hormone produced by the pituitary gland, often referred to as the lactogenic hormone because it plays a key role in milk production.

Low levels of prolactin are typically not a cause for concern. However, high prolactin levels in both men and non-lactating women can indicate potential issues such as infertility, low sexual drive, and erectile dysfunction in men. Elevated prolactin can also signal underlying conditions, such as pituitary tumors or hormonal imbalances, which may require further medical investigation.

Haemoglobin is the protein in red blood cells responsible for carrying oxygen throughout the body.

• A high haemoglobin level indicates an increased amount of oxygen in the blood, which can be a sign of dehydration or other conditions such as lung or heart disease.
• A low haemoglobin level suggests a reduced oxygen-carrying capacity, often linked to anaemia or other health issues like nutritional deficiencies, blood loss, or chronic diseases.
