Fibrinogen
Fibrinogen (factor I) is a glycoprotein in vertebrates that helps in the formation of blood clots.
Specimen: Sodium Citrate

Folic Acid
Folic acid or folate is a B vitamin Folate is necessary for fertility in both men and women. It contributes to spermatogenesis. Therefore, it is necessary to receive sufficient amounts through the diet to avoid subfertility. Also, polymorphisms in genes of enzymes involved in folate metabolism could be one reason for fertility complications in some women with unexplained infertility.

Method: CLIA
Loinc: 14928-6
Free T4
Free thyroxine (free T4) tests are used to help evaluate thyroid function and diagnose thyroid diseases, including hyperthyroidism and hypothyroidism.
Specimen: Serum
Reference Values:
Euthyroid: 0.78-2.19 ng/dl
Hypothyroid: <0.78 ng/dl
Hyperthyroid: >2.19 ng/dl
Method: CLIA
Loinc: 3024-7
Fructose Semen
Fructose is produced in the male reproductive tract by the seminal vesicles and is released into the semen during ejaculation. Fructose is the energy source for sperm motility.
Specimen: Semen
Reference Values:Present
Method:
Loinc: 10574-2
FSH
It is synthesized and secreted by gonadotrophs of the anterior pituitary gland. FSH regulates the development, growth, pubertal maturation and reproductive processes of the body.
