SR. NO TEST TEST COMPONENTS Method Specimen/Transport TAT Clinical Applications
1 Donor Specific Antigen (DSA) (Luminex) Antigen-Antibody reaction is determined (positive or negative). Luminex solid phase assay Donor: Sodium Heparin Vacutainer (3ml x 5 vials); Recipient: Plain Vacutainer (3ml x 2 vials) 3 days This test is ordered after a potential donor has been identified. It helps to determine if the recipient has specific antibodies against antigens present on the donor's lymphocytes. Serum from the recipient is mixed with white blood cells (T and B lymphocytes) of the donor. If any reaction is detected (a positive result), it would indicate the incompatibility between two of them. The cross match result should be always interpreted along with the known information about the recipient's HLA antibodies and the donor's HLA typing.
2 LCM-CDC Antigen-Antibody reaction in the format of percentage Manual Donor: Sodium Heparin Vacutainer (3ml x 5 vials); Recipient: Plain Vacutainer (3ml x 2 vials) 3 days This test is ordered after a potential donor has been identified. It helps to determine if the recipient has specific antibodies against antigens present on the donor's lymphocytes. Serum from the recipient is mixed with white blood cells (T and B lymphocytes) of the donor. If any reaction is detected (a positive result), it would indicate the incompatibility between two of them. The cross match result should be always interpreted along with the known information about the recipient's HLA antibodies and the Donor’s HLA Typing

9 Polycystic Kidney Disease Autosomal Dominant Polycystic Kidney Disease - PKD1 and PKD2 genes Autosomal Recessive Polycystic Kidney Disease - PKHD1 Next-Generation Sequencing Preferred sample EDTA Blood (3ml x 3) Amniotic Fluid/ CVS will be accepted based on clinical criteria on special consideration 20 Days This test is used to screen for mutations in the genes responsible for PKD. This test helps in determining the necessity for screening in other family members. In cases of a positive finding in a patient of child bearing age, Preimplantation genetic diagnosis can be performed in most cases to help conceive a child without the pathogenic mutation.
10 Alport Syndrome (COL4A5) Coding region along with certain intronic padding of COL4A3, COL4A4 and COL4A5 genes associated with Alport Syndrome. Next-Generation Sequencing Whole blood 3ml in EDTA vacutainer 20 Days This test is used to screen for mutations in the genes responsible for ALPS. This test helps in determining the necessity for screening in other family members. In cases of a positive finding in a patient of child bearing age, Preimplantation genetic diagnosis can be performed in most cases to help conceive a child without the pathogenic mutation.

Detection of pathogenic mutation in an individual can lead to a diagnosis, possible prognosis, and prospective therapy treatments.
12 Renal Hypouricemia (SLC22A12 & SLC2A9) SLC22A12 and SLC2A9 Gene Sanger Sequencing Whole blood 3ml in EDTA vacutainer 20 Days Detection of pathogenic mutation in an individual can lead to a diagnosis, possible prognosis, and prospective therapy treatments.
