Question 1

What affects protein S levels?

Accepted Answer

The following factors can influence protein S levels:
1. Family History: Inherited protein S deficiency is the most common cause of low protein S levels.
2. Liver Function: The liver produces most of the protein S in the body. Liver diseases or impaired liver function can decrease protein S production, leading to low protein S levels. 
3. Vitamin K Deficiency: Protein S requires vitamin K to function properly. Vitamin K deficiency can impair the production and functioning of protein S, resulting in reduced protein S levels.
4. Medications: Certain medicines, such as warfarin (a blood thinner) and hormonal contraceptives, can affect protein S levels. Warfarin inhibits the synthesis of vitamin K-dependent proteins, including protein S, while hormonal contraceptives can increase protein S levels.
5. Pregnancy: Protein S levels naturally decrease during pregnancy due to increased consumption and changes in blood clotting factors.
Inflammatory conditions and autoimmune disorders can impact protein S levels.
6. Other Conditions: Certain medical conditions, including cancer, thrombosis, and infections, can influence protein S levels.

Question 2

What does it mean when your protein S is high?

Accepted Answer

A high protein S level is relatively rare and is usually not a cause for concern. Temporary increases in protein S levels can occur during acute inflammation or in response to certain illnesses. Consult your doctor if your test results are abnormal. They will interpret the results to determine the significance of high protein S levels and will help you with further investigation or treatment if necessary.

Question 3

How do you know if you have protein S deficiency?

Accepted Answer

Protein S deficiency can be inherited or acquired. Symptoms or indications of protein S deficiency may include:
1. History of blood clots: Protein S deficiency increases the risk of abnormal blood clotting, leading to disorders like pulmonary embolism, deep vein thrombosis (DVT), or recurrent miscarriages in women.
2. Family history: Inherited protein S deficiency often runs in families, so a family history of blood clots or known protein S deficiency increases the suspicion of the condition.
3. Frequent or unusual blood clotting: Individuals with protein S deficiency may experience recurrent or unusual blood clotting events, especially at a young age or without apparent risk factors.
4. Pregnancy complications: Women with protein S deficiency may have a higher risk of complications related to the pregnancy, such as recurrent miscarriages, preeclampsia, or fetal growth restriction.

If protein S deficiency is suspected based on clinical symptoms or family history, a healthcare professional may order specific laboratory tests to measure protein S levels. These tests may include total protein S antigen or functional assays to evaluate the activity of protein S.
