Hematology is the science or study of blood and blood diseases. In the medical field, Hematology includes the treatment of blood disorders and malignancies.

Following tests are conducted under Hematology such as -

• Haemoglobin
• Haemogram/CBC
• Platelet Count
• PBS For Malaria
• Rapid Malaria Test
• ESR
• AEC
• BTICT
• Prothrombin Time
• Blood Group
• Direct Coombs Test

Biochemistry is the application of chemistry to the study of biological processes at the cellular and molecular level. It emerged as a distinct discipline around the beginning of the 20th century when scientists combined chemistry, physiology, and biology to investigate the chemistry of living systems.

Some Tests come under it are -

• Blood Sugar Fasting / PP
• Blood Sugar Random+
• GTT
• Sr. Amylase
• Sr. Lipase
• Sr. Calcium
• Sr. Phosphorus

Renal function tests (RFT) are a group of tests that may be performed together to evaluate kidney (renal) function. The tests measure levels of various substances, including several minerals, electrolytes, proteins, and glucose (sugar), in the blood to determine the current health of the kidneys. 

Some Pathological Investigations are -

• Blood Urea
• Sr. Creatinine
• Sr. Uric Acid
• Proteins
• Sr. Electrolytes (Na/K/CI)

A lipid profile test assesses the level of specific fat molecules called lipids in the blood. 

• Total Cholesterol
• Low Density Lipoprotein (LDL) cholesterol,
• Very Low Density Lipoprotein (VLDL) Cholesterol
• High Density Lipoprotein (HDL) Cholesterol and Triglycerides.

Liver Function Test (LFTs or LFs), also referred to as a hepatic panel, are groups of blood tests that provide information about the state of a patient's liver. 

Some Pathological Investigations under this are -

• Sr. Bilirubin
• SGPT/SGOT
• Sr. AIK Phosphatase

What is a cardiac enzyme marker test? An enzyme marker test is a blood test to measure specific biological markers (biomarkers) in your blood. High (elevated) levels of cardiac enzymes can be a sign of a heart attack or another heart problem. Cardiac enzymes are also called cardiac biomarkers. 

Pathological Investigations such as -

• Sr. LDH
• Sr. CPK MB

Clinical pathology is a medical speciality that is concerned with the diagnosis of disease based on the laboratory analysis of bodily fluids, such as blood, urine, and tissue homogenates or extracts using the tools of chemistry, microbiology, hematology, molecular pathology, and Immunohematology. 

Some Pathological Investigations under this are -

• Urine Routine
• Urine BS / BP
• Urine Pregnancy Test
• Stool Routine
• Stool Occult Blood
• Semen Analysis

Bacteriology is the branch and speciality of biology that studies the morphology, ecology, genetic s and biochemistry of bacteria as well as many other aspects related to them. This subdivision of microbiology involves the identification, classification, and characterization of bacterial species.

Pathological Investigations are-

• Sputum For AFB
• Culture Sensitivity
• (Stool, Urine / Blood / Pus)

A hormonal assay test is performed to give an indication of metabolic processes and conditions, or 'hormone imbalance'.

Pathological Investigations are -

• T3/T4/TSH
• Free T3 / Free T4 / TSH
• FSH/LH/Prolactin
• B HCG

One criterion used in a vitamin assay is increase in body weight in response to different amounts of a specific vitamin in the diet. 

Some of the Pathological Investigations under this are-

• Sr. Vitamin B12
• Sr. Vitamin D 3
• Sr. Folic Acid
• Sr. Iron
• Sr. Ferritin
• Sr. Tibc

Serological tests are diagnostic methods that are used to identify antibodies and antigens in a patient's sample.

Some Pathological Investigations under this are -

• Widal
• HIV
• HBs Ag Australia Ag
• HCV
• VDRL
• RA
• A.S.O
• CRP
• Dengue Ns 1
• Dengue IgG/IgM
• Chikungunya IgG/IgM
