Analysis (H)
All our Analysis with the initial letter “H”.
Haptoglobins
Haptoglobin testing is used primarily to help detect and evaluate hemolytic anemia and to distinguish it from anemia due to other causes , however, it cannot be used to diagnose the cause of the hemolysis.
Specimen: 0.2 ml Serum
Reference Values: 30-200 mg/dl
Method: Nephelometry
Loinc: 4542-7
HAV IgG
The HAV IgG test detects the IgG antibodies that develop later in the course of the disease. IgG antibodies remain present for many years, usually for life, providing protection against recurrent infection by the same virus. The IgG test is used to detect past HAV infections and may occasionally be used to determine if an individual has developed immunity from a previous infection, in which case a vaccine is not necessary.
Specimen: Serum
Reference Values: >20 IU/L : Reactive
A positive result indicates an existing or past infection or antibodies after Hepatitis A vaccination.
Method: CLIA
Loinc: 5179-7
HAV IgM
The HAV IgM antibody test detects the first antibody produced by the body when it is exposed to hepatitis A. This test is used to detect early or recent infections and to diagnose the disease in people with symptoms of acute hepatitis.
Specimen: Serum
Reference Values: Negative
Method: CLIA
Loinc: 13950-1

HCG (Total β-HCG)
Human chorionic gonadotropin (hCG) is a hormone produced by the syncytiotrophoblast, a portion of the placenta following implantation. The presence of hCG is detected in pregnancy tests. Some cancerous tumors produce this hormone , therefore, elevated levels measured when the patient is not pregnant can lead to a cancer diagnosis.

HIV 1 & 2 RNA
Each viral particle of HIV-1, the infectious agent of AIDS, contains two copies of the full-length viral genomic RNA. Encapsidating two copies of genomic RNA is one of the characteristics of the retrovirus family. The two RNA molecules are both positive-sense and often identical , furthermore, each RNA encodes the full complement of genetic information required for viral replication. The two strands of RNA are intricately entwined within the core of the mature infectious virus as a ribonuclear complex with the viral proteins, including nucleocapsid.
