Protein S testing: Protein S testing typically is done prior to pregnancy because the testing is unreliable during pregnancy. There is a clotting disorder called Protein S deficiency that can be diagnosed when levels are low in the non pregnant state. Treatment is usually Lovenox (enoxaparin) or Heparin. Discuss your specific case with your obgyn to determine the next steps. ...Read more

With new advance technology. What's the most superior way to detect all ID's and Toxins? Protein? or Antibody or Antigen? This is better then DNA?

No single answer: This varies tremendously depending on the possible infectious agent. The speed of the test, the sensitivity, the specificity and the cost are all factors. Anyone offering a simplistic answer is someone without real-life experience here. ...Read more

What test indicate old or previously treated infectious diseases? Antigen, toxin, protein, anti-body..?

What test indicate old or previously treated infectious diseases? Antigen, toxin, protein, anti-body..?

Extremely complicate: It depends on what disease. Syphilis for example has several tests..Rpr using a reagin looking for an antibody to the spirochete. Clostridium difficile looks for toxin a and b. Hiv western blot looks for HIV envelope proteins. Igm indicated a more recent infection while igg a longer time interval. It is not as simple as it seems defining old vs new..Tb for instance is a good example. ...Read more
